It arrived with an 87% charge, which was nice as I only had to charge it 1 hour.Added Armstrong power connectors to make it easier to charge/discharge as it needs to be portable for my application.I have not had a chance to test the battery yet, but the first time I picked it up, the handle broke 😩*** Upadate 12/05/24 *** still satisfiedI have done a quick test on this battery and I'm impressed, I get a calculated 285 Ah (extrapolated) of usable capacity - have to wait and see long term, but initially except for the broken handle (which is a problem for me) this battery is fantastic.*** update 12/11/24Battery was under 50% charge, inverter shutdown (load 310 watts). Grabbed alternate inverter, also would not power on. Indoor charger (75F) - will not charge (says it's disconnected). All cables are tight.I REALLY want this battery to work, I am in a remote location and need it badly. I was so excited to get this monster, but it's not working out well - zero full discharge uses.Per the manufacturer, I have over-discharged this battery and it does not seem to be recoverable (I did try with an expensive intelligent charger). I thought this is why it has a BMS, to prevent this (?).So why 5 stars? Because the Cairhornce gave me a full refund, despite the run around to try and rejuvenate the battery. This manufacturer came to this conclusion quickly and sent me a refund and that's how you can tell if you should do business with someone, not when things are good, but when things are bad.

so you think you pay almost $1,000 for the lithium ion battery and it should be a good thing right? so the thing is pretty useless, I got a solar setup I got a trickle charger I got an inverter a 3000 watt inverter you can't run anything off of it more than 3 minutes it starts beeping it's going dead I mean how long you got to charge this thing I've had it how many days now and it's useless it it's useless it is like am I supposed to have bought 10 of these things or something? I mean I have an air fryer it will work you run it for like 30 seconds I mean come on it's a 3000 watt inverter too so don't go blaming my inverter!!!!!

Received battery in good condition . Package arrived in great shape. Checked battery charge, it was at 80%. I hooked it up to charge and it took 7.5 hours to bring to 100%. I bought this battery to pair with a 3500 watt converter and run my slide in camper while off grid camping . The only complaint I have so far is that the battery doesn’t come with any paperwork. No warranty card or specs on BMS sz or temp range. I’m in the Houston area so high temperature might be an issue but I will cross that bridge when I get there.
