Worked fine as and kept charge 99%Great for back up items in storms.

I got this battery as an upgrade for my tent trailer. I initially installed it and I had all kinds of weird problems like low voltage and even a positive ground at one location? I wrote a strongly worded email to the company thinking the battery had caused it since everything worked before I installed it. I phoned an electrician friend and he told me it was likely a poor connection of bad ground wire. After a spirited and vocal field testing session...he was right! The battery was fine! I even took to my father's shop, where he has an actual battery load tester. To both of our surprises, it provides a FULL 100 amps under load and tested over 100 amp hours of capacity. Way above what I expected of such a budget battery. So that night I checked my email and found the manufacturer had immediately responded and was willing to bend over backwards with help and apologies! Offering to replace it, offer tech advice and make it right however they could?!?!? I then ate a full serving of crow and emailed then back with my findings. They were kind and wished me well, never being anything other than great! Needless to say, I've ordered 5 more for another project and they're working great too!!!

I used it over a week, made 3 large pots of rice on a 1000w invertor. Then used it to top up power on my lead acid batteries on my travel trailer over a week long trip. Lightweight.

Great alternative to lead acid.

This was my first time delving into lithium batteries and I’m glad I landed with these batteries. They were shipped promptly and received timely. The packaging was well done with no damage observed at all. These batteries were installed in my travel trailer. I was a little concerned about the on board charger doing the job but it charged them right up to 100%. I disconnected the trailer from shore power and ran several interior 12v lights for 2 days. It was still showing full on the display. Next I extended and retracted the power leveling jacks along with the front power jack and slide out. Everything acted as though it was still connected to shore power. It’s only been a few weeks but I’m impressed.

I would like to let you know that these will not work with all RV systems. My slide out only works on battery power and even with using a trickle charge battery charger. And then using landline power my slide out still will not work because the batteries do not comply with my camper or RV. I would advise never buying this for your RV. This is a poor description and an invalid product for RV camper trailers.

Lightweight, easy to install. I've been through several charge/discharge cycles, and it provides the stated energy output and voltage.

I sent these batteries to help people with no electricity. So far they work great. Recommended.
