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.

I bought the 100 ah mini. This arrived with a 14% charge for shipping safety. It took about 3 hrs to charge to 100% the first time with the LiTime charger. I have used it twice now with my MinnKota Powerdrive for my Autopilot 120 kayak. Each outing was about 2.5 hours with constant use. About 10% of the time was full power, with the remaining time divided between slow trolling and spot lock. The battery never went below 96%!!! Recharging to 100% took about 10-15 minutes.

Amazingly nice product, batteries hooked up perfectly, app installed in seconds and battery status is great. The app allows you to create an item, such as "boat" and link the batteries together to show the 36v that my boat uses. Very nice all around. Batteries are very light compared to older batteries. Purchased minn kota 3-port lithium charger, all working together terrific. Batteries arrived in good shape and very quickly. Highly recommend this battery.

We mostly Boondock camp in our RV, struggled keeping our single interstate battery charged. We would have to run our generator so we would have power and the battery would not charge with the solar panel. Bought two of these, camped for 10days and the batteries never dropped below the fully charged mark. Solar panel keep them charged and only ran the generator when we needed to make coffee and use the microwave.

Purchased these to operate the 24 volt trolling motor on my boat. Basically half the weight of the old batteries. I have a very snug compartment that the batteries install into, and these fit perfectly (replaced lead acid group 27s). Used them for the first time on a week long fishing trip to Canada and they performed flawlessly! Only minor complaint is if you don't have cellular data signal, you apparently can't pull up the System View of the batteries on the Bluetooth app, but you can still see the charge of the individual batteries. Aside from that, so far I am extremely happy with them! Very timely shipping and easy to install!

EDIT: Added more context, support was helpful but not understanding to the problem they introduced. They offered a full refund to return. Read updates below, I opted to keep. As others have mentioned, the BMS does weird things. Charging will hold at ~13.5 V and then suddenly disconnect causing a charger fault. Reading voltage will show ~12.8 V at all times after charging and after placing a small load. Subsequent charging causes same issue. Using a smart charger with LiFe profile, when BMS disconnects the charger shows a fault. The 100Ah Mini, *OLD* 100Ah Standard and 100Ah self-heating never did this. Only the TM has ever done this. Have used other manufacturer batteries all without issue prior. UPDATE 3: Charging with a load is key to preventing the charging circuit from disconnecting. THe new BMS protection will introduce a voltage drop, which some chargers see as a fault. It is done at the BMS when the battery is at ~14.4V. Having a small load on the battery will allow the charger to detect ~14.4V and stop the charge. Without the load the circuit will completely disconnect and even caused large spikes as the charger attempted to ramp voltage. So standard bench charging or no-load charging (likely with some uses) is not without issues. This applies to ALL LiTime models going forward. UPDATE 2: Having a lot of remote/off-grid experience, I have been trying to provide more details to LiTime. Only response has been that it is expected. Unacceptable response. This also includes the newest "Standard" 100Ah, same problem. Will not charge to 14.2/14.4V without BMS disconnecting. UPDATE: LiTime has offered refund, so will update from there. Have attempted a few more cycles to just see if this is a balancing issue and it doesnt seem to have changed, disconnects the circuit during charge, reconnect shows lower voltage. Solar charge will not be happy with that.

Replaced an 88 a/hr group 28 battering powering boat electronics. Lasts over a long weekend of fishing easily vs sweating whether you’ll last the day. LiTime batteries are well worth the money.

I needed a replacement battery for my Goal Zero 1250 power station. This one works perfectly. I also use Li Time batteries on my travel trailer. They work great!
