I recently went camping offgrid in California. I utilized this standalone 12v 100Ah to power my diesel generator, running it all night long and enabling the inside of my tent to be 72F while outside it was 23F. I also powered some lights while I camped, using this battery. It shocked me how long it lasted, given the draw of power from the diesel heater all night long. Would absolutely buy again, given its portability and performance.

Bought 2 (4 packs) for a total of 32.15 KWh storage for an off-grid 15 kW DC solar paneled, 48 volt storage riverfront get-a-way. Always charge batteries individually to 100% SOC before connecting in series/parallel configurations.
Make sure charger (in my case is part of inverter) is set at a maximum voltage level lower than will let any single battery in the series string (4 in my case for 48v) cut off the charge voltage MOSFET. In my case I found this to be 54.9 volts or 13.725 for each of 4 batteries in series.
Very satisfied with purchase value and especially the Bluetooth monitoring of each battery.

Delivered on time. Tested a few times with a 12 volt trolling motor I borrowed. Worked very well. I haven't tried it on my 36 volt TM but I'm sure they will be fine.
