Review: New battery, not old stock! - After a full initial charge, I discharged the battery down to 10.5 V, and it rebounded quickly to 11 V. So far, I’m very happy with the performance. This test was done at a 2-amp discharge rate, and the voltage stayed extremely steady right up until cutoff. A heavier load test is coming next. Before running a higher-current test on the 20 Ah battery, I also tested the 100 Ah battery I purchased—and the results were excellent. I had to be gentle with my tester to pull enough current over a reasonable time span, but I managed to measure 99.12 Ah over approximately 9 hours and 57 minutes, at an estimated 8–10 amp draw. These were the very first charge and discharge tests, completed within days of receiving the batteries. I plan to continue testing and will update this review if anything changes. As of now, $120 for 100 Ah and $46 for 20 Ah feels like a very solid value. Update (2-7-26): After a few months of light, occasional use, both batteries are still performing great. I recently purchased a BT90 Pro battery tester with lithium testing capability. After partially discharging the 100 Ah battery and letting it sit unused for a couple of months, the tester still reported it as being in excellent, full-charge condition. Out of curiosity, I also tested the battery’s 100-amp maximum discharge rating using a Harbor Freight CEN-TECH 100-amp load tester. It successfully delivered 100 amps for 9 seconds without the voltage dropping below 12.6 V. The battery stayed cool throughout the test, and the BMS did not trip. Everything continues to work exactly as expected. I’ll keep testing and updating if anything changes.
Review: Great product - Works great haven't had any problems out of this battery. Have been going o 6 months now problems

## Features

- [Grade A+ Cells & Advanced BMS with Low-Temp Protection] 12V 100Ah LiFePO4 battery uses advanced Grade A+ cells that are UL tested, ensuring a 10-year lifespan and over 5,000 cycles. Built-in premium 100A BMS, there are 6 layers of safety protection, including low temp protection (Charge cut-off: 23℉~41℉, Discharge cut-off: -13℉~5℉ ), high temp, over-charge, over-discharge, over-current, and short circuit protection.
- [Series and Parallel Connection] Whether creating a 48V lithium ion battery bank or a 12V 400Ah power system, our Dr.Prepare LiFePO4 batteries are both supported. You can even wire up to 16 batteries in series and parallel to build a powerful home battery bank system with a power of 20.48 kWh.
- [Improved active bms protection] optimized circuit can handle cell balancing, over-current cutoff, over-charge cutoff, over-discharge cutoff, high and low temperature cutoff, and short circuit protection for increased performance and longer lifetime.
- [3,000 Lifespan, 10-Year Lifetime] Up to 80% capacity for 3,000 cycles in recommended conditions, while the typical sealed lead-acid batteries have only 500 cycles. Provides roughly a 10-year lifetime of daily use.
- [2-3 Times More Power] Dr.Prepare 2 Pack of 12V LiFePO4 batteries provide a maximum of 1,280 Wh power output, which is 2 to 3 times more powerful than typical SLA batteries of the same size. 100A max continuous discharge current powers most electrical devices, such as Off-Grid, RV, Solar Power, Boats, Inflatable Boat, Marine, Camper, Trolling Motor, Home Energy Storage, Scooter, Kayak, Canoe etc..
- [Kind Reminder] It's an energy storage battery, not a car battery, starting battery or golf cart battery. We suggest 2 batteries are required for a 24V trolling motor or a 62-86lb thrust trolling motor. CAUTION: An over-current protection device (circuit breaker or fuse) is required. Per Coast Guard regulations, each ungrounded conductor must be protected by a manual, trip-free breaker or fuse. 60A circuit breaker sold separately in the Dr.Prepare Store.
- [About Recharging] Use a 12V (14.6V) 5A/10A/20A/50A charger specifically designed for LiFePO4 batteries or a solar panel with controller to recharge DR.PREPARE 12V 100Ah LiFePO4 Battery. Kindly note that Do not use other brand general-purpose chargers to avoid potential damage. Dr.Prepare's compatible charger is available in our store. Lead acid battery charger CAN'T recharge DR.PREPARE LiFePO4 Battery. Each battery must be fully charged separately by a 12V LiFePO4 charger before in series.

## Questions & Answers

**Q: Does this 12V 100Ah battery offer low-temperature protection?**
A: Yes, it does. When the temp reaches 23℉~41℉, this lithium battery will stop being charged, and when the temp reaches -13℉~5℉, the battery will stop discharging. Ideal for harsh and rugged environments. It also has high temperature protection.

**Q: What are the charging voltage and charging current for this battery?**
A: The max. charging voltage is 14.6V and the max. charging current is 50A. For optimal charging performance, we highly recommend adjusting the voltage to 14.2V-14.6V and using a 20A charger.

**Q: Does this battery have low voltage cut-off protection?**
A: Yes, it does. When the discharge voltage is lower than 11.1V, the battery will shut off automatically.

**Q: Can I use my lead acid battery charger to charge the lithium battery?**
A: We recommend using a lithium battery compatible AC to DC charger to charge LiFePO4 batteries, or else cause unreversible lifespan damage to the batteries. You can also charge these batteries using compatible solar charge controllers and solar panels.
