My rig (30 FW) did not have the lipo option at the time so my project for this fall/winter was to add lipo and extra solar.
Ended up with 3 BB 100ah lipo batts and added 2 renogy 175w solar panels for 550w total (the rule of thumb for solar and lipo is 200w per 100ah batt) in a series/parallel 24vdc arrangement for the panels.
I also removed the PWM solar controller and installed a Victron MPPT so I could run the 24v S/P solar in and 12vdc out to the batts. Rerouted the batt cables for the Victron shunt. Put the Victron headend into the spot on the pillar I removed the PWM solar controller. And the BIM 225 for the LiBIM 225 for chassis charging.
And on the 7th day rested.. working on this stuff, roof, batt compartment and under the rig does take a toll on these retired bones.
