I’m extremely impressed with this 12V LiFePO4 battery. It’s lightweight, compact, and delivers reliable power far beyond what my old lead acid batteries could handle. The long cycle life and built in safety protections give real peace of mind, Easy to recharge and dependable.

This is NOT a good battery. I have used it 5 or 6 times now, and the voltage will drop unexpectedly at random times below 9 volts. I haven't put a meter on it when it drops, but my ham radio transceiver shows a low voltage, and a light comes on when voltage drops below 9 volts, and the signal sent from the transceiver is distorted. A minute or 2 later voltage is ok again, then it does the same thing again randomly. This is after having the battery fully charged and only using it under load for a short period of time. I have owned other brands of these type batteries that have lasted hundreds of charging cycles with no problems, but this one is not good at all. Don't waste your money on it!

Works great! Using it in the toy car for the kids

I've never used lithium in my UPSs. So, honestly I'm a little nervous. I mean you always see incidences of lithium batteries bursting into flame. That would be bad enough when you're at home, perhaps even worse while you're away or asleep. So, I am testing sparingly. They seem to be of fine quality. They are light, but that is the nature of a different type of battery. They function as a battery. Easy to install as any battery would be. So, if they hold up I suppose they are a good value. Time will tell.

Ordered two 12V 8AH batteries. I fully charged both batteries and used them in my daughters power wheels. Went to recharge both batteries and only one will charge. I have tried to contact the manufacture but I am unable to reach them due to the product being fulfilled by amazon. I am really disappointed in the quality of these batteries. I now have only one working battery and questioning how long this one will last. Would like a way to contact the manufacture on how to replace the defective battery.

I tried this in my APC Back-UPS ES 725 (model BE725BB) but it failed the power-on test. I suspect that most of these lithium batteries will be the same so be sure to watch some of the many videos on YouTube explaining the use of these as replacements for SLA batteries in a UPS. There are other brands of these batteries on Amazon that have been proven to work with APC units (ask Rufus) although none specifically with my model that I can find. I will stick with a SLA battery for now and maybe by the time it dies, the lithium UPS story will have improved.

Handy to have for various project like setting up solar lighting, etc. Lightweight and compact so very versatile in its uses

I installed the battery in a 12v kids ride on car. It works ok for first two months. Now it only works for half hour after I unplug it from charger. If I don’t keep it charging. The battery will drain in one day. I don’t really recommend it.
