Where did you source your battery?OverTheTopCargoTrailer wrote:John
Lithium are so simple , a kindergarten kid can program them.
Now the Blue 100 ah CLAB or CALB? cells are about 3+ years old and out of production. I got many of them and they still work great. 12 cells = a 300 ah battery , about same as 600 ah flooded.
I set my charge controller / charger at 13.9v max the inverter LBCO at 12.5 volts. Most of the time batteries are at 13.2v....
Your system matches up to a 300+ solar panel.
Batteries don't charge well below 40F , keep them between 40F and 85F for longest life.
To start with charge all your 12 cells inline together at 3.35v max over 1-7 days allowing them to equalize.
In an rv configuration they won't need BMS ......I would recommend don't charge with more than 40 amps , or discharge over 30 amps for longer duration. 100 amps for 1 -3 minute micro is ok.

Charge controller set at 13.9 when charging. Inverter set at 12.5v LBCO-
low battery cut out. NO BCM required.
No temperature protection?
Temperature protection for what ????
No detecting bad cells or just unbalanced issues?
Told you RV use no problem. Max 40 amp discharge, 30 amp charge.
We're talking thousands here, and I'm very forgetful and careless, will be away at work with kids running the show...
12 cells used $50 =$600
And at 300-500 AH, obviously can scale up C rates (and costs) proportionally.
Yes if one cell goes bad it can be replaced. Or 4 cells added for extra 100 ah. BUT THEN REBLANCE RECOMMENDED.
