12V 50Ah Lithium Battery, Rechargeable LiFePO4 Battery with Built-in 50A BMS Board, 5000+ Deep Cycles, Perfect for RV, Solar System, Fishing Boat, Camper and Off Grid Applications

Holds its charge, is light,and is reliable. I use it on my 10 foot kayak for range and time on the water.

Great buy. Good quality and last for hours with my 35 lb thrust trolling motor

Worked well for about 1.5 years, then failed. Maybe this would be a good product for another job, but not for a boat electronics power source. The 10-year life it mentions in the description wasn't right on this item. Its showing fully charged but won't support a load. Tried using the customer service to troubleshoot and was directed back to Amazon.

Great little battery right here. We purchased 4 of them just to try them out and they are light weight, come charged, and so far doing what I need them to do. I will be buying lots more of these.

Bought this to replace my original flooded battery that went bad after a year even though it was on a trickle charger. This one was the same price and and advertised as more powerful as well as a much longer life, plus it weighs next to nothing compared to my original. I'm looking forward to putting it to work.

I purchased two 12.8v 50ah batteries for my 24v trolling motor. I have had zero complaints. They have been work horses,and lasted for 3 days of prefishing in high winds on a single charge. The other night i backed the boat in from a long day on the lake and plugged them into charge when I noticed my charger was throwing a code saying it was not charging. I have tried everything to get one of the two batteries to take a charge and it will not. I’ve been trying to find a way to contact the seller with no luck. (Any help would greatly appreciated) this is not a bad review things just happen. I just wish I could have gotten a little more out the one battery.

I love this lightweight battery! I bought it to power my trolling motor and the wench on my truck. Works great.👍 I can even charge it with solar power.

I charged battery when it arrived with the appropriate Lithium charger. It tested a little low. I took it to an Auto store to have them test it on their tester. It read, Failed and showed 256 watt Hours. It is supposed to have 640 Watt Hours. The seller kept telling me to take pictures of battery on charge, pictures of charger, pics of tester, pics of charger on tester. I gave up
