DC HOUSE 12V 6Ah Mini Lithium LiFePO4 Deep Cycle Battery, 4000+ Cycles Lithium Iron Phosphate Rechargeable Battery for Lighting, UPS, Power Wheels, Fish Finder, RV, Ride-on Toy, Camping, Built-in BMS

I used two of these to replace the lead-acid batteries in a ceiling track hoist for a disabled person. The old batteries were about four years old, and the typical "alarm system" lead-acid type. These LiFePO4 batteries have the built in charge controller, so I knew it would just be a straight across swap. My hope was to have more battery capacity than the old ones so we could go longer between charges. The experience of changing battery tech was more than expected. These things have about four times the life of the old style battery. They hold voltage high during the discharge cycle, so the power level of the motor remains consistent throughout the use cycle. That means the motor is performing near peak power until right before a charge is needed. Since these batteries weigh less than the old ones, the lift is easier to pull along the track when unloaded. All good stuff. The only concern that I've got is that the charge percentage displayed by the lift's electronics is calibrated for the lead-acid discharge curve. These will read at a high level (80%-100% charge) until they're ready to die. Once you see a 70% on the screen, you've only got a few more seconds of power before it absolutely needs to charge. That's not going to cost this a star, as it's a function of the changing the battery tech that the electronics weren't built to understand.

This is a great replacement for my Craftsman garage door opener that had an old lead acid battery that was 14 years old. I had to modify one of the terminals to make it fit the connector I had, but no big deal. It charged right up and has worked perfectly ever since. It weighs a fraction of the lead acid battery and has about double the energy density.

I bought 10 of these for an engineering project. So far they're used daily, charged weekly, and appear to be a great value!

Worked great. Used to repower a 12v dirt bike for a 5 year old. Holds a charge long enough to ride for 45 minutes or so. Recharges well.

Works great.. got the for a 24 electric scooter that was only 6 months old and the 12v6ah gel battery's would only hold a charge for about 200ft going slow.. new lifepo4 mini 12v6ah can put 4 in place 6ah gel and the chair is still at a full charge after riding for about 1 mile around and the weight of the chair is easier to pickup and put back in house.. will buy more for my other chair..

It seems like these batteries are a crap shoot if you get ones that work. Bought 2 last year and they are great. Bought two this year and not so good. Came fully charged, used once, and now they will not take a charge.

I use the battery to power my Xiegu G90 ham radio and it worked fine for that. I haven’t run the battery down yet but so far it has healed up great.

Use to run a small little fan to cool receiver when play loud music. Sony receiver would go into protect mode to help from over heating. Battery runs fan for ever.

This battery is compact so it fits in my float tube pouch. I was fishing for a day and it held it's charge, going down very slowly. Perfect for a fish finder

Excellent battery. Light weight easy to charge with a lifepo4 hobby charger ( I charge at 3 amps). Rated capacity tested at 100% .

too early to rate performance. it's a summer item for me with a solar grid

Fits perfectly in Cyberpower 650va ups. plugged in and worked instantly. Dimensions given were accurate.

They fit perfectly in my Emerson UPS, and have been functioning great so far. My UPS requires 4 in series (48V), which has always made replacement expensive. These didn't cost too much more than lead acid, and they're so much lighter. Hopefully they last a long time!
