Light and handles 5hp load easily
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)

LiFePO4 vs AGM... LiFePO4 wins no doubt
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.

Some Manufacturers actually value their reputation and take pride in their.product and owner base.
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

Lighter, smaller and longer lasting....
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.

It fits in a Razor MX 650. If you cut second battery tray out.
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

Keeps the equipment running
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.

Holds charge well - slow discharge rate
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.
