Epoch Batteries and LiTime both sell drop-in 12V LiFePO4 batteries for RVs, boats and off-grid systems, but they compete in different ways. Epoch, which describes itself as veteran-owned and designed and engineered in the USA, sells three 12V lines. Its Essential Series carries an 11-year warranty, and its Group 24 Eco Series 100Ah was listed at $325 on Epoch’s store on Oct. 17, 2026. LiTime focuses on value: its 12V 300Ah battery was listed at $599.99 on LiTime’s U.S. store the same day, with a 5-year warranty. Below I compare the two brands’ 100Ah, 300Ah and 460Ah batteries spec by spec, with cost-per-kWh and warranty math.

The Short Answer
- Pick Epoch if you want the longest warranty (11 years on Essential, Pro and Elite Series), U.S.-based support, built-in heating and Bluetooth on most 12V models, and Victron communication on select models.
- Pick LiTime if you want the lowest price per kWh, IP65 sealing on models like the 12V 300Ah, higher BMS ratings on the 460Ah, and a wide range of sizes and feature options.

300Ah Comparison
| Spec | Epoch 12V 300Ah Essential | LiTime 12V 300Ah |
|---|---|---|
| Energy | 3.84kWh | 3.84kWh |
| Continuous discharge / charge | 200A / 200A | 200A / 200A (2,560W) |
| Peak | 400A for 3 s | 800A for 1 s |
| Heating / Bluetooth | Yes / Yes | No (low-temp charge protection; LiTime sells separate cold-weather models) |
| Case size | Group 31 | 20.55 x 9.45 x 8.58 in |
| Weight | 58 lb | About 64.15 lb |
| Ingress rating | IP54 | IP65 |
| Series / parallel | 4S / 4P | 4S / 4P |
| Warranty | 11 years | 5 years |
| Price (Oct. 17, 2026) | $1,249 | $599.99 |
The Epoch fits a Group 31 tray, which makes it an easier swap for an existing battery box, and it adds heating and Bluetooth. The LiTime costs less than half as much, has a higher peak rating and IP65 sealing, but it’s longer and doesn’t self-heat.
460Ah Comparison
| Spec | Epoch 12V 460Ah Essential | LiTime 12V 460Ah |
|---|---|---|
| Energy | 5.89kWh | 5,888Wh |
| Continuous discharge | 200A | 250A (3,200W) |
| Peak | 400A for 10 s | 800A for 1 s |
| Heating / Bluetooth | Yes / Yes | See LiTime listing for your variant |
| Case | Group 8D | BCI Group 8D |
| Weight | 84 lb | See LiTime spec sheet |
| Warranty | 11 years | 5 years |
| Price (Oct. 17, 2026) | $1,599 | $1,079.99 |
For large 12V inverters, LiTime’s 250A continuous rating gives more headroom per battery. Epoch notes that its 460Ah suits roughly 2,000-2,500W inverter systems and that you should size continuous loads to the 200A rating.
Worked Example: Cost per kWh and per Warranty Year
| Battery | Price | kWh | $ per kWh | Warranty | $ per warranty year |
|---|---|---|---|---|---|
| Epoch 100Ah Eco | $325 | 1.28 | About $254 | 6 yr | About $54 |
| Epoch 105Ah Essential | $549 | 1.34 | About $410 | 11 yr | About $50 |
| LiTime LiHeat 100Ah G24 | $409.99 | 1.28 | About $320 | 5 yr | About $82 |
| Epoch 300Ah Essential | $1,249 | 3.84 | About $325 | 11 yr | About $114 |
| LiTime 300Ah | $599.99 | 3.84 | About $156 | 5 yr | About $120 |
| Epoch 460Ah Essential | $1,599 | 5.89 | About $271 | 11 yr | About $145 |
| LiTime 460Ah | $1,079.99 | 5.89 | About $183 | 5 yr | About $216 |
Math: price / kWh, and price / warranty years. LiTime wins on upfront cost per kWh at every size, often by a wide margin. Epoch narrows the gap, and sometimes wins, once you spread the price over its longer warranty. The 300Ah pair comes out nearly even per warranty year.
Worked Example: RV Weekend
An RV using 1.5kWh a day (fridge, lights, water pump, fans and device charging) for three days needs 4.5kWh. A single 300Ah from either brand (3.84kWh) needs about 0.7kWh of daily solar to finish the weekend. A single 460Ah (5.89kWh) covers it with about 1.4kWh to spare. If you camp below freezing and charge from solar in the mornings, the Epoch 300Ah’s built-in heating saves you from buying a separate heated model. With LiTime, choose one of its self-heating models for that use.
Features That Separate Them
- Cold-weather charging: Epoch builds heating into its Essential, Pro and Elite 12V lines. LiTime offers self-heating as a separate LiHeat model line, while many standard LiTime models use low-temperature charge protection instead.
- Monitoring: both brands have Bluetooth apps on their Bluetooth models. Epoch’s Elite Series adds Epoch Cloud for remote monitoring, and LiTime’s Smart ComFlex adds Victron communication. See our LiTime battery monitor app setup guide.
- Sealing: most Epoch 12V batteries are IP54, splash and dust resistant. The Pro and Elite lines are IP67, and LiTime’s 300Ah is IP65.
- Support: Epoch offers U.S.-based support and a “check my fit” service. LiTime runs local U.S. warehouses with free shipping and a 30-day price guarantee.
Charging Notes for Either Brand
Both brands use 12.8V nominal LiFePO4 packs, so the same rules apply. Use a lithium (LiFePO4) charge profile, turn off lead-acid equalization and desulfation modes, and keep charge current within the battery’s rating. Epoch lists 50A as the recommended charge current for its 100Ah and 105Ah Group 24 models (100A max) and a 14.6V BMS high-voltage cutoff on the Eco 100Ah. For a 300Ah bank, both brands allow up to 200A, but a 0.5C rate (150A) or less is gentler on the cells and easier on your wiring. Epoch also publishes an 11.2V inverter/load cutoff for its 300Ah, which is a good low-voltage setting to copy into your inverter.
How to Choose in Four Steps
- Work out the size you need. Add up daily watt-hours, then pick a capacity with at least a day of reserve.
- Check the current. Divide your inverter’s watts by about 11V to estimate DC amps. Above 200A per battery, the LiTime 460Ah’s 250A rating, or two batteries in parallel, makes sense.
- Decide on cold-weather charging. If you’ll charge below freezing, choose a heated model: Epoch Essential, Pro or Elite, or LiTime LiHeat.
- Weigh warranty against price. Use the cost-per-warranty-year table above to see which matters more for your budget.
FAQ
Is Epoch better than LiTime?
Neither is better across the board. Epoch leads on warranty length, built-in heating and support. LiTime leads on price per kWh and has higher BMS ratings on some sizes.
Which has the longer warranty?
Epoch: 11 years on Essential, Pro and Elite Series, and 6 years on Eco. LiTime offers 5 years.
Do Epoch batteries have self-heating?
Yes, on its Essential (heated models), Pro and Elite 12V lines. The Eco Series has no internal heating and blocks charging below 32°F.
Can I parallel these batteries?
Both brands support up to 4S4P on most models, and Epoch’s Eco 100Ah allows up to 16 in parallel. Don’t mix brands or capacities in one bank.
Do they work with Victron systems?
Both can be charged by Victron chargers using a LiFePO4 profile. For closed-loop communication, Epoch’s Elite Series offers Victron VE.Can, and LiTime’s Smart ComFlex lists Victron communication.
Which is better for boats?
Look for higher ingress ratings. Epoch’s Pro and Elite lines are IP67 and LiTime’s 300Ah is IP65, while most Epoch Essential models are IP54. Both brands also sell dedicated marine and trolling-motor models.
Which is lighter?
At 300Ah, the Epoch is lighter: 58 lb versus about 64.15 lb for the LiTime. At 100Ah, they’re close, at 21-22.7 lb.

Bottom Line
Both brands make strong LiFePO4 batteries, and the right choice depends on what you value most. Choose Epoch for an 11-year warranty, built-in heating and Bluetooth, and U.S.-based support. Choose LiTime for the most kWh per dollar, IP65 options and higher BMS ratings on large batteries. Check the current LiTime 12V 100Ah self-heating price on Amazon, and compare with Epoch’s store pricing before you buy.
