Have this bank positive terminal to alternator b+ and inverter +, / with ground to inverter -.
No getting the 13.8 or better charge.
Odb2 shows 13.8 as electrical system volts, but not getting to lithium bank.
Can someone tell me what's up?
Was I supposed to ground lithium to alternator frame?

So what does this power? just like lights? Does it get inverted to AC so you can run a griddle or something?
I'm fascinated to learn more.
I work in electrical utility sub stations, and I've been working on projects recently replacing the back up battery systems in some stations. I'm fascinated now with all things battery. Battery back up , battery storage. Solar to battery, you name it battery related I wanna know about it.
Pack will be connected to 4Kw max inverter to run cooking appliances in campervan. Also to backup power portable power cell, and sla battery charger.
I expect under 2.3Kw usage at any given time, so about 55-65% DOD means above 5000 recharge to full cap.
I'm so excited, I will be getting another as soon as I can.
