A solid battery but make sure you get the correct ah for your application! I bought this battery to power a minn kota ultrex quest trolling motor on a small fiberglass bass boat (18'). I went with 50ah based on multiple reviews and online forms that stated this battery will last all day and at times two days. After using it for the first time i was impressed how long the run time was, but this is not a big enough battery for my application. 50ah is not large enough for fishing windy conditions on bodies of water with current. With moderate use it only lasted about 4 hours, and in some conditions even less. With that said, i plan to purchase a second 50ah battery to run in parallel and i will be sticking with this brand. Also, since this battery is not bluetooth enabled it was impossible for me to monitor the battery level as i used it. I would suggest a bluetooth battery to anyone that plans on running their trolling motor moderately hard so you're not stranded down river or down wind of your boat launch.

I bought three of these LifePO4 36v 50ah batteries to replace my 6 old 6v lead-acid golf cart batteries. I had discussions with the technical support folks about any potential issues with my specific application and we mutually decided that three of these batteries could replace the old 6 batteries. Obviously I had to change the battery wiring from series connections (6S x 6v = 36v) to (3P x 36v = 36v 150ah). The battery was delivered extremely quickly, arrived perfectly packed in two sturdy cardboard boxes and the battery surrounded by a custom foam liner inside the inner box. The tech docs include all necessary charging and usage info, as well as warranty, etc in a very nice plastic file. All in all, I was very surprised and impressed by the obvious quality of the battery, and pre and after sales support. I have only recently installed the batteries so cannot comment yet on their performance or longevity but I am extremely hopeful that based on everything that I've seen and experienced thus far, everything will work 100% as expected! HIGHLY RECOMMENDED!

The battery was delivered and only had 2v and would not take a charge. The charge was attempted with a rated charger. Even at the lower charge for shipping ith shouldn't be this low. The battery had either a bad cell or BMS. I requested an exchange which was denied. I had to go through Amazon just to return the battery at no cost to me. Then the seller would not sell another battery at the original price. I would stay away from this seller.

Excellent battery that works really well with my RC mower project! Nominal voltage is around 40v so it can be a replacement to the 40v power tool batteries. The terminal lugs are also high quality.

Omg this thing is amazing, power for days, shipping fast, amazing packaging to protect the battery and the stickers etc might seem extra and who wants a battery sticker right?? Me because it's the little things in life that make a purchase experience great. And this was way more worth the exact same price 10mAH 36v replacement for my ebike was and now instead of 40 to 60 miles on lowest pedal assist to make batteries last longer. I can go over 100 miles using throttle only with zero pedaling before the first bar of battery leaves the screen!! Now it's a hunting ebike with game trailer, kayak trailer, and compound bow and fishing rod holder!!
