They were mounted in a battery box, slightly compressed and terminals were vertical. Leak was from the bottom of the cell, no where near vent. I bought them from a "reputable" referral from this forum. I'm going to reach out to them to see how they handle situation.

I just discovered a leaking cell today. Lishen Cells, 300AH and installed for two weeks in the 5th wheel RV. Rig was stationary during this time and no visible short or damage other than now having delamination of the blue shrink wrap due to being wet. Batteries were 4s for a single 12v battery...

I originally asked them about running 3 separate batteries each with individual bms running in parallel. I did not ask about your 3 separate pack set up although I have seen some use a common bus bar but seemed like additionalw wiringand failure points. Daly rep said no BMS in parallel at all...

I would check voltage at the fan see what you're getting there. Sounds like a PCM alarm for low/high voltage. Alternator might be throwing the high voltage alarm from the alternator.

Have a 400 amp alternator that will be wired back so technically not the 7-pin, but you get the drift. Genset is going to be my primary way to recharge off grid. I really don't think I'll be going full solar other than plug in panel. With 60 gallons of fuel on board and really only running the...

I've looked at going 48v, but the problem is I have the house power that runs off 12v, plug in solar panel that is 12v, 12v supply from 7-pin, generator on board that in I'm already trying to figure out how to with with, etc. I think if I were starting starting from scratch I'd be 100% 48v.

Also, what are the pros/cons of Option "a" of 4s3p with 3 separate BMS OR Option "b" of 3p4s with a single BMS

Thank you for the welcome. There's a LOT on this forum and have been reading for weeks. I wouldn't say life or death, but it's a 12v system in a place now and I cannot rewire (anything touched past distro panel voids warranty and on a $140k rig, warranty is pretty important. Basically it will...

Hello all, I am new to the world of DIY Lithium and I just ordered : 12 pcs - 3.2v @ 300AH LiFePO4 cells I plan to run a 4s3p configuration for my 5th Wheel Toy Hauler. I'll be running (2) 3kw Victron Multi-plus off this battery bank with estimated peak amps @ 500A. I had originally planned...
