LiTime Batteries Complete Spec Sheet: 12V 100Ah, 200Ah, and Mini Models
LiTime, formerly associated with the Ampere Time brand, produces LiFePO4 batteries aimed at RV, marine, solar, truck, and off-grid applications. This guide compares the LiTime models most likely to be considered for a 12V battery upgrade: the Classic 100Ah Group 31, the 100Ah Group 24 Smart Self-Heating battery, the 100Ah XtraMini, and the 200Ah XtraMini.
The important distinction is that these are not simply different capacities in the same case. They have different BMS ratings, low-temperature behavior, dimensions, Bluetooth features, and installation requirements. Prices and product specifications can change, so confirm the product page and measure your battery compartment before ordering.
LiTime battery lineup at a glance
| Model | Rated energy | Size | Weight | Bluetooth | Self-heating | BMS | Best fit |
|---|---|---|---|---|---|---|---|

The lineup creates an easy trap: "100Ah LiTime" does not identify one specific battery. A Classic Group 31 battery, a Group 24 self-heating battery, and an XtraMini can all be rated at 100Ah while differing substantially in size and features.

The important limitation
The Classic battery's operating-temperature range can be mistaken for a cold-weather charging feature. The product page lists discharge operation down to -4F, but it also states that this model does not have low-temperature charging protection and should only be charged above 32F.
That means the battery may be able to discharge in cold conditions, but the owner must prevent charging while the cells are below freezing. If the battery will be charged outdoors during winter, use a model with a low-temperature cutoff or self-heating system instead.
LiTime 12V 100Ah Group 24 Smart Self-Heating
The LiTime 12V 100Ah Group 24 self-heating model adds Bluetooth monitoring, low-temperature charging protection, and integrated heating to a smaller Group 24 case.

Self-heating is not free energy
The heating element draws power from the battery or charging system. In cold weather, some of the battery's available energy may be used to warm the cells before charging begins.
This is why a self-heating battery should not be evaluated only by its 100Ah rating. The relevant questions are:
- How cold will the battery compartment become?
- Will the battery be connected to shore power, solar, or an alternator while heating?
- Is the charging system large enough to supply both the battery and the heating load?
- Does the installation have enough ventilation and clearance?
For a winter RV or marine installation, the self-heating Group 24 model is more capable than the Classic model. For a warm-weather system, the additional cost and heating hardware may not provide much practical benefit.
LiTime 12V 100Ah XtraMini
The LiTime 12V 100Ah XtraMini is designed for installations where a regular Group 31 or Group 24 battery is too large.
Specifications
| Specification | LiTime 12V 100Ah XtraMini |
|---|---|

The XtraMini's main advantage is not higher capacity. It stores the same rated 1,280Wh as the other 100Ah models while taking up substantially less space.
The tradeoff is that a Group 22NF battery is not a drop-in replacement for every Group 24 or Group 31 compartment. The small case may require a new hold-down, adapter, or different terminal cables.
LiTime 12V 200Ah XtraMini
The LiTime 12V 200Ah XtraMini is the high-capacity model in this comparison. It combines 2,560Wh of rated energy with a 200A BMS in a relatively compact case.
Specifications

Does the 200Ah XtraMini fit a Group 31 battery box?
Do not assume that the answer is yes.
The product is marketed as a Group 31-sized battery, but the listed dimensions are not identical to every standard Group 31 box. In particular, the published height requires attention. LiTime lists the product body at 9.45 inches high on the product page, while a launch announcement describes the overall height as 10.04 inches when terminal height is included. A battery box, tray, lid, hold-down, or seat base that barely clears a standard Group 31 battery may not clear the XtraMini's terminals.
Before buying, measure:
- The usable length and width inside the compartment.
- The height to the lowest obstruction, including the lid.
- Terminal height and cable bend radius.
- Hold-down location.
- Ventilation and service access.
- Whether the tray can support a 44.5-pound battery.
This is one of the most important practical details missing from generic LiTime comparison pages.
LiTime BMS and cold-weather behavior
The models in this lineup do not all have the same BMS.
Classic 100Ah
The Classic Group 31 model uses a 100A BMS but does not list low-temperature charging protection on the current official product page. LiTime advises charging it only when the battery temperature is above 32F/0C.
100Ah Group 24 self-heating
The Group 24 model combines a 100A BMS with low-temperature charging protection and a heating system. Charging stops below approximately 32F and can resume after the cells warm to approximately 41F. The heating system then raises the internal temperature before normal charging.
100Ah XtraMini
The 100Ah XtraMini includes a 100A BMS and automatic low-temperature charge and discharge cutoffs. LiTime lists charging cutoff below 32F, discharge cutoff below -4F, and charging recovery at approximately 41F.
200Ah XtraMini
The 200Ah XtraMini uses a larger 200A BMS. It is intended to support significantly higher continuous loads than the 100Ah versions. However, a 200A BMS does not mean every inverter, cable, fuse, or disconnect in the installation is rated for 200A.
The protection limits are only one part of the system. Size the cables, overcurrent protection, busbars, disconnects, and inverter according to the maximum expected current.
Cost per cycle
Cost-per-cycle calculations are useful, but only when the price and cycle-life assumptions are stated clearly.
The original BatteryTrail content plan requested this planning comparison:
LiTime planning benchmark
- Assumed LiTime price: $251
- Cycle life: 6,000 cycles at 80% DoD
- Calculation: $251 / 6,000 = $0.0418
- Rounded result: approximately $0.042 per cycle
Current product-page examples
Prices change frequently. At the time this guide was researched, LiTime's product pages displayed approximately:
| Model | Example displayed price | Published cycle basis | Approximate cost per published cycle |
|---|---|---|---|
| Classic 100Ah | $335.99 | 6,000 cycles at 80% DoD | $0.056 |
| Group 24 self-heating 100Ah | $409.99 | 6,000 cycles at 80% DoD | $0.068 |
| 200Ah XtraMini | $679.99 | 6,000+ cycles at 100% DoD | About $0.113 |
These are not lifetime guarantees. Cycle life depends on temperature, charge rate, discharge rate, storage conditions, cell balancing, and the manufacturer's test procedure.
The original BatteryTrail brief also requested a Battle Born comparison using a $679 price and 3,000-5,000 cycle range:
- $679 / 3,000 cycles = approximately $0.226 per cycle
- $679 / 5,000 cycles = approximately $0.136 per cycle
The meaningful conclusion is not that LiTime is always cheaper in every situation. It is that LiTime's lower purchase price and published cycle claims can create a strong cost-per-cycle advantage, while premium brands may compete through warranty terms, support, established dealer networks, and installation confidence.
Real-world boondocking runtime
A 12V 100Ah LiTime battery is rated at approximately 1,280Wh:
12.8V x 100Ah = 1,280Wh
At an 80% depth of discharge:
100Ah x 80% = 80Ah usable capacity
80Ah x 12.8V = 1,024Wh usable energy
At a continuous 50W load:
1,024Wh / 50W = 20.48 hours
So a realistic idealized estimate is approximately 20.5 hours, not 25.6 hours, before inverter losses and other system inefficiencies.
The 25.6-hour figure comes from dividing the full rated energy by 50W:
1,280Wh / 50W = 25.6 hours
That assumes 100% of the rated energy is available. It is not an 80% DoD estimate.
For a 12V 200Ah battery:
12.8V x 200Ah = 2,560Wh
200Ah x 80% = 160Ah usable capacity
160Ah x 12.8V = 2,048Wh usable energy
2,048Wh / 50W = 40.96 hours
Actual runtime will be shorter or longer depending on the load profile. A refrigerator, for example, may draw 40W while its compressor is running but cycle on and off. Inverter standby consumption, wiring losses, battery temperature, and high-current loads also reduce usable runtime.
Compatible chargers
LiTime specifies a CC/CV charging profile for these 12V batteries.
The commonly listed profile is:
- Charge voltage: 14.4V +/- 0.2V
- Recommended charge current for 100Ah batteries: 20A
- Recommended charge current for the 200Ah XtraMini: 40A
Compatible charging sources include:
- A 12V LiFePO4 AC-to-DC charger
- A LiFePO4-compatible DC-to-DC charger
- A solar charge controller configured for LiFePO4
- A generator feeding a suitable LiFePO4 charger
- A properly configured alternator charging system
LiTime's product documentation also lists 14.2V-14.6V as a practical recommended charging-voltage range for some 12V charging setups. The charger's actual profile should be checked against the manual for the exact battery variant.
Do not use a lead-acid charger with an equalization mode unless the manufacturer specifically confirms compatibility. Equalization voltages and temperature-compensation behavior can be inappropriate for LiFePO4 batteries.
Which LiTime model should you choose?
Choose the Classic 100Ah Group 31 if:
- You want the simplest lower-cost option.
- Your battery compartment accepts Group 31 dimensions.
- You can prevent charging below freezing.
- You do not need Bluetooth monitoring or self-heating.
Choose the Group 24 Smart Self-Heating model if:
- You operate an RV, boat, or off-grid system in cold weather.
- You need a smaller Group 24 form factor.
- You want Bluetooth monitoring.
- You expect the battery to be charged when temperatures may fall below freezing.
Choose the 100Ah XtraMini if:
- Your installation has limited space.
- You want Bluetooth and low-temperature protection.
- You need a lighter battery.
- Your compartment can accommodate a Group 22NF-sized battery and a custom hold-down.
Choose the 200Ah XtraMini if:
- You need roughly twice the rated energy of a 100Ah battery.
- You have high inverter or motor loads.
- Your installation can support the 200A BMS and associated wiring.
- You have verified height and terminal clearance rather than relying only on the "Group 31" label.
Installation checklist
Before ordering a LiTime battery:
- Match the exact model, not just the amp-hour rating.
- Measure length, width, and height inside the battery compartment.
- Include terminal height in the measurement.
- Check the lid, seat base, hold-down, and cable bend radius.
- Confirm whether the model has low-temperature charging protection.
- Confirm the recommended charging voltage and current.
- Size the fuse and cables for the BMS and expected load.
- Do not mix different LiTime models in the same bank without confirming compatibility.
- Use batteries of the same voltage, capacity, age, and BMS rating when building a bank.
- Do not use these deep-cycle batteries as engine-starting batteries unless the specific product is explicitly designed for starting duty.
Frequently asked questions
Can the Classic LiTime 100Ah battery charge below freezing?
No. The current Classic product page says this model does not have low-temperature charging protection and should only be charged above 32F/0C.
Is the Group 24 self-heating battery the same as the Classic 100Ah?
No. Both are 12.8V 100Ah batteries, but the Group 24 version has a different case, Bluetooth, low-temperature charging protection, and self-heating.
Does the 200Ah XtraMini fit every Group 31 battery box?
No. Verify the exact internal dimensions and terminal clearance. The product page and launch materials present slightly different height measurements depending on whether terminal height is included.
Is the 100Ah XtraMini the same as the 100Ah Group 31?
No. The XtraMini is a separate compact model. It is lighter and smaller, but it uses a Group 22NF-sized case rather than the Classic battery's Group 31 case.
How much usable energy does a 100Ah battery provide?
At 80% DoD and a nominal voltage of 12.8V, the simple estimate is approximately 1,024Wh usable energy. Actual usable energy varies with load, temperature, cutoff settings, and system losses.
Can LiTime batteries be used as starting batteries?
The Classic LiTime 12V 100Ah product page states that the battery is intended for energy storage rather than starting applications. Use a dedicated starting battery unless the exact LiTime model is explicitly rated for engine starting.
Bottom line
LiTime's 12V lineup offers strong value, but "LiTime 100Ah" is not a sufficient specification. The Classic Group 31, Group 24 self-heating, and 100Ah XtraMini models solve different installation problems, while the 200Ah XtraMini adds substantially more capacity and a 200A BMS.
The best buying decision depends on four things:
- How much usable energy you need
- Whether the battery must charge below freezing
- How much physical space is available
- How much current the system must deliver
For warm-weather budget installations, the Classic 100Ah remains the straightforward choice. For cold-weather use, the Group 24 self-heating model is the safer fit. For compact spaces, the 100Ah XtraMini is the smallest option in this comparison. For high-capacity RV systems, the 200Ah XtraMini is compelling - but only after you confirm the actual height and terminal clearance in your battery compartment.
