I messed up and ordered the 200ah battery. It took me a day to come to the conclusion that I really needed the one with Bluetooth. It’s going in a boat where, after thinking about it, it would be much easier to have Bluetooth in the battery than mount an external monitor to keep track of the SOC.I canceled my order on Amazon and they said they would try. Litime ships the batteries from their warehouses so they would have to stop it. The next day it was still in limbo so I contacted Litime and asked them to cancel the order. They said that it had already shipped but they would try and get FedEx to ship it back to them. If that didn’t work I could refuse the order when it showed up and if that didn’t work out they would send me a return label. Turns out FedEx returned it to them before it left Texas.So, even though it was my mistake that I made a rash order and purchased the wrong battery they had my back the whole time. I can’t thank them enough.On to the battery.I have 4 Litime 100ah minis in my cab over camper and another 4 100ah minis in an enclosed trailer. Never a problem and they perform to spec. I have a friend that is convinced that there has to be something amiss, that such a small battery can’t really be 100ah but I’ve tested them and drew 100amps (all 4 batteries are in parallel for 400ah) from them for a little over 3.5 hours and the SOC at the end was about 10%. Didn’t want to draw them down any lower, they had lived up to their promise.Now, on to the 200ah Bluetooth battery. Haven’t had it long so all I can say is the Bluetooth function was worth the additional $. No external hardware needed to determine the SOC so it was well worth it. Given the customer service I’ve experienced I’m confident that if I do have a problem Litime will handle the issue.Couldn’t be happier with all 9 batteries I’ve purchased from them.

Battery was lost in shipping but seller was proactive and notified me and worked out expedited shipping for replacement. Battery so far has been great.

This battery is great. It works seamlessly with my 2 50amp solar panels on my camper, even charging in the partial shade. I was able to camp completely off grid without a generator and the only thing I couldn't use was my coffee maker. I did not use the AC or microwave because I was camping at a high altitude, therefore not that hot, and I cooked outdoors. I love the wireless connection to my phone and could check my battery charging and battery life at any time I was close to the camper.

Quick shipping, arrived in good condition…App setup and charging……Very happy 😊 so far.****** note in order to connect to bluetooth it need to be charging/discharging *********

Battery is supposed to arrive at 50% charge and get charged fully before use. The battery that was shipped to me was at 1 volt and the charger wouldn't even recognize it even in "wakeup" mode. Tried contacting seller here but the limited dialog of the automated system simply falls back on "sorry, no returns". I guess I have a $450 paper weight.

Good guality and price. Works as advertised

Great upgrade from two lead acid batteries!

Packaged well and arrived on time. Great communication from the seller on order status, shipping, and a wonderful follow up message to make sure it was received and as expected. I wish all sellers were this concerned about their customer!!
