LiTime 51.2V(48V) 60Ah Lithium Golf Cart Battery, Built-in 120A BMS, 15000 Cycles Rechargeable LiFePO4 Battery, Support up to 4kW Motor, Max 6.14kW Continuous Power Output, Perfect for Golf Carts

Used it for a a year and a half, boondocking last winter for 5 months in the SW desert. Worked flawlessly. Using solar for 90% of the charging and generator for the no sun days. Still as good as new. This was the best upgrade on my travel trailer and well worth the money. I will never go back to lead acid now that lithium is priced comparable to standard batteries.

Great batteries! I paralleled three of them for my camper.

I used this battery to replace an Optima AGM battery in my 36-volt trolling motor system that went bad after six years. I am impressed with the light weight - about 1/3 of the Optima. It was MUCH easier to get installed since there is very little room in the battery compartment of my boat (20 ft Triton). The new battery also costs $100 less than the Optima. The battery arrived well packaged in foam. It charged up overnight with my 10 amp boat charger. The only issue so far is the terminals. They use an 8mm bolt to attach the cables; this is difficult to do when reaching back into the battery compartment since I couldn't see the part of the battery where they attach. Total "by feel" job and if I'd dropped the bolt it would have been gone forever. Next time I'll get a couple of 8 mm stud bolts and make post-style terminals. After I had everything installed I ran the boat on the trolling motor wide open (112 lbs thrust) for about a mile with no issues. I'll update this review in a few weeks when I've had a chance to go on a few fishing trips. If it works out I'll replace the other two TM batteries this winter with these LiOn batteries.

Great battery, great price
