## Features

- [ Coulomb Tech Meter] In 2025, updated with advanced coulomb technology, this meter maintains ≤5% error accuracy. Its digital screen displays the discharging current and voltage in the discharge state, the remaining capacity and voltage in standby mode, and the charging current and voltage in the charging state. Unlike voltage-based meters (which show only battery bars with 30-40% inaccuracy, and only shows battery voltage with level bars.), DR.PREPARE meter provides exact numerical data.
- [Grade A+ LiFePO4 Cells & Low Temp Cut-Off Protection] The advanced Grade A+ cells inside are UL tested, ensuring a 10-year lifespan. When the temp reaches 23℉~41℉, this lithium batteries will stop being charged, and when the temp reaches -13℉~5℉, this LiFePO4 battery will stop discharging. Low temperature cut-off protection can keep lithium batteries healthy.
- [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. Dr.Prepare battery provide every customer with 10-YEAR product support. If you have any question, please contact us directly. Dr.Prepare customer service team will provide professional knowledge and service to solve your problem!
- [5,000 Cycles, 10-Year Lifetime] DR. PREPARE LiFePO4 battery has 5,000 cycles at 60% deep discharge and 3,000 cycles at 80% deep discharge, providing about a 10-year lifetime, while only 500 cycles for the sealed lead-acid batteries. The 12V rechargeable LiFePO4 battery provides a maximum of 1,280Wh power output, which is 2 to 3 times more powerful than SLA batteries of the same size. Continuous discharge current can power most electrical devices, such as RV, boats marine, off grid, fish finders, solar power, electric chair wheel, camping, cmaper home alarm system, scooters.
- [2-3 Times More Power] Dr.Prepare 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. Monitor the remaining power capacity via the built-in LED display.
- [Warm Tips] It's an energy storage battery, not a car battery, starting or golf cart battery. We suggest using one battery with a 12V 36~55 lbs thrust trolling motor, and 2 batteries are required for a 24V 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for UPS batteries
*by D***. on July 21, 2025*

These worked perfectly to replace the batteries in an old APC UPS I had kicking around. It's back to full functionality and weighs less too. Have saved a bunch of money bringing my old UPSs back to live vice buying new ones.

### ⭐⭐⭐⭐⭐ Works very well
*by R***P on July 24, 2025*

Very good customer serviceVery fast shippingUsed the battery for half a day on a 27lbs thrust trolling motor and only used 10%I would say this is a great battery even though this is the first one I ever owned

### ⭐⭐⭐⭐ Perfect fit and 30% lighter
*by K***S on February 5, 2024*

Decided to convert from SLA to LFP (LiFePO4 Lithium) batteries for my UPSes. These batteries fit perfectly.I charged each with my Lithium charger and installed them, plugged into grid power, check voltage and frequency, 122 volts @ 60 hertz, hooked up to a load source and powered up at 64 watts. Pulled plug from grid and it kept running as expected. I did notice the voltage dropped from 122 to 112 volts but frequency stayed at 60 hertz, showed it would run another 55 minutes with that draw.Very much lighter as it has 2 batteries and each is half the weight of the original, so I reduced by about 4-6 pounds.
