DR.PREPARE 2 Pack of 12V 100Ah LiFePO4 Lithium Battery, 1280Wh Deep Cycle Lithium Iron Phosphate Battery with 100A BMS, Low & High Temp Protection, for RV, Solar Power, Off-Grid, Home Energy Storage

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.

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

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.

Great batteries for the money. Ran my trolling motor no problem

I purchased 2 batteries from this company. Within 10 cycles, one of them quit working. The voltage is 11.6v. It will not take a charge. I have tried force mode, battery repair and even contacted the manufacturer of my charger. It will not charge. My charger works just fine on the second battery.I contacted customer service for the battery manufacturer. They are not in the US so it takes a day to get a response. Once they responded, they asked for voltages. I sent the information they asked for. The next night they replied saying now they need a video of me hooking up the charger and taking voltages. The next night they replied with I didnt tighten the terminals with a wrench and requested another video. So I sent it. The next night they are saying they want the charger out put voltage. I told them that the charger does not start charging unless a battery is detected. The next night they said they need a video of the charger not charging.I am done with this. If you want a marginal battery and a bunch of headaches with the warranty people get this battery. If you dont want all of the BS, get a different brand.

I absolutely love my batteries, I use them for a 24v 70# trolling motor and it is amazing how long they last compared to my group 34's. After owning them for about a year, I did have an issue with one battery. It lost continuity, but the company was awesome to work with and they replaced it under warranty. Will definitely do business again.

I charged them fully and they’ve been working for months. Perhaps I’ll come and edit next time. I have to charge them again.

I put it in a UPS. Charged very fast. Very light compared to the old lead acid batteries.
