Upgraded Rechargeable 6V 6Ah LiFePO4 Battery with USB Charge Design, 6 Volt Lithium Battery 2000+ Cycles with BMS (F1 Terminals) for Deer Feeder 1 Pack

I bought these as a replacement battery for my kid's mini motorcycle, and so far they’ve been excellent. They hold a strong charge and run much longer than the original lead-acid battery I replaced. I charged one up the first time and it's still charged, and that was like 2 months ago! He rides the thing multiple times a week! The build feels solid, and I’m impressed by the upgrade in both performance and weight savings. The USB-C charging is super convenient too, because I lost the actual charger for my kid's mini motorcycle. A very worthwhile investment if you’re replacing older-style batteries.

It is Eazy to use and charge at the same time. This functionality makes these batteries quite useful for solar panels and small tools or speakers with amps. Plus, I think the LiFe type batteries are better than Li ION.

Light weight, just purchased a couple more and comes with charging cords

The order was received the very next day and was put in use immediately. It was ordered for a deer feeder and worked like a charm! The feature I like the most is that they are rechargeable which is great for hunting!

I had a really old emergency radio/flashlight/warning flasher that I bought some time in the 1990s. It still works well, but the lead acid battery needed replacing constantly and the run times would die down as the batteries aged, or if you fully drained it. It's meant for emergencies, but now I can actually use it more often with the lithium battery, and not leave it charging constantly until I need it for an emergency.I did have to drill a little hole on the side of the battery compartment behind the access panel to be able to connect to the lithium batteries' USB charging port. I didn't want to use the simple charger for the lead acid battery, in case this battery gets damaged by that charger. I've already used it for the flashlight and this battery should last much longer than with the lead acid. It's also much lighter.The flashlight was meant to last 7 hours on the 6V incandescent bulb. The fluorescent tubes were meant to last 7 hours or 3.5 hours if both were on. The radio was meant to last 14 hours. I have used it during an emergency and the single fluorescent tube did last 7 hours on a brand new lead acid battery, as advertised. It might last twice as long now. I did switch out the main bulb with an LED, so I wonder how much longer this will last now. It might be 4 times as long. I might test it one day.I like the fact that there shouldn't be any degradation of the battery if it gets fully drained. The run times of lead acid get shorter and shorter after each full drain of the battery. This means I can use it much more often and not worry so much about battery degradation from the sulfation of the lead acid plates.

Very poor quality. From full charge to dead sitting on the shelf. Charged with the supplied cord and with a dedicated lithium charger. Neither made any difference. Still dead a day later.

Excelente

I use these in my spinning wing decoys and have no complaints. They take a bit to charge but that is what it is. Happy with them
