Says 15v, but below says over 14v will blow it up. It cannot do 6s (x) 8A balance current. nope. Can only 33w per. So ther...

Re: 'on board' 1.5kW charger. Which alibaba supplier?

Last rv I worked on had 220v appliances.

Shore power was 220v or 110.

We installed ( 2 @7kw) 14 kw of inverters and 30 kwh of brand new lifepo (at 6800$. ).... @48v.

It still doesn't keep up with the AC for more than a day. Lol.

If it uses current sensors, route wire (2 gauges thinner than the existing wire) in parallel with the existing wire. I did the shunt mod to one of my controllers (40 amp -> 70 amp) and it has run cool and fine for over a year. If it does, then it's time for a new controller. Could you explain the m...
