51.2V25Ah Lithium LiFePO4 Battery, Built-in 50A BMS, Max. Up to 2560W Power, 48V Lithium Battery with 15000 Cycles for Trolling Motor, RV, Solar Power, Scooters, Camping, Lawn Mower.

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 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

Great battery

Works great. Reduced the weight on my boat, too.

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.

I put this baby to the test and it is great. Hooked up to a 24v 1200W inverter: it ran the big kitchen-refrigerator for 6-hours.

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.

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.
