Hi Mike I have another query on your Lead Carbon and LifePo4 setup.

It seems that you have both banks connected in parallel until the voltage falls to 22 volts, then the Lead Carbon is the only battery running the system.

I have read a bit about charging LIFE P04 batteries and I know that my MPPT regulators have different settings for charging different battery types.

So will the charger voltages that my regulators are set for ( 28.8 volts) damage or undercharge the Lithium batteries.

thanks
Pete
