GrenerPower 12.8V100Ah Group 31 Dual Purpose LiFePO4 Battery, Built-in 200A BMS, IP66 Waterproof, and Max. 900A Marine Cranking Starting Lithium Battery, Up to 4P4S for Outboard Motors, Boat, RV, Home

Worked great on my 5hp trawler motor, capacity is enough for an hour of full throttle. It's light enough to easily hit swap with another in the field (I have 2 of these batteries fully charged when I go out, just in case)

I upgraded my power wheelchair from AGM batteries to LiFePO4 and OMG, the difference that it made is unbelievable. Range increased by several miles and performance is vastly improved as well. I have literally tried to run these down, but so far, nope.

Great battery

Initially I didn’t receive a helpful response to replace the battery from Amazon, However the manufacturer learned about my situation and were very interested in learning about how the battery was being used and requested some basic tests to verify its current condition. As a result, they initiated a prepaid return whereupon they would exchange it for a new battery. I can’t say enough for the battery’s manufacturer. They value their reputation and will stand behind their product. I would definitely buy another product from GrenerPower

Works like a million $$. Smaller, lighter and much longer lasting than lead acid. Not cheap on a per battery basis but given the fact that I only needed one vs. 2 lead acid batteries, a great deal.

I Put it in a razor mx650. It works awesome. It barely fits if you cut battery tray out. I paired with a 2000w 48v vevor motor kit Lasts about 4 hours. Recommended charge rate is 5 amp. Takes about 6 hours from fully dead

Used for and emergency communications link. The battery gives no issues it holds it's power well. It is monitored with battery monitoring equipment and it runs quite well.

Good as a backup battery where the 7A capacity is sufficient. Charged right up with my LiFePo4 charger at 2A. A pair in a small UPS would be great.
