Adding more batteries
Good Afternoon all! Fully charged my 2 x 6v batteries in my class A work well and provide me 208AH (104 usable). I have 300 watts of solar that works great in the summer to keep me going however in...

Hi,
For a conventional lead acid flooded cell current acceptance at 85% state of charge may be about 12.5 amps per 100 amp-hours of storage. Increasing the voltage at that point simply causes the cells to gas. The only time we want high voltage is if we are trying to equalize the cells in a bank.
The boondocker may be limited by the OEM wire size. I'd never dream of trying to send 60 amps down the #8 wire that came in the RV. When I used to do double conversion, the most I saw was about 32 amps from a 40 amp PD converter with the wizard set to boost.
For your situation:
1 conductors per phase utilizing a #4 Copper conductor will limit the voltage drop to 2.36% or less when supplying 60.0 amps for 10 feet on a 14.6 volt system. (That's .34 volts)
or
1 conductors per phase utilizing a #2/0 Copper conductor will limit the voltage drop to 0.90% or less when supplying 60.0 amps for 10 feet on a 14.6 volt system. (that's .146 volts).

Can someone break down for me bulk charging.... If my battery is at 50%.. should a 60-amp converter kick in and charge at 60amps?
What about at 70% charge & 80% charge?
