I’m part upgrading a 12 year old Sprinter LWB camper. I’ll retain the main management/wiring system. This provides shore charging of house or starter batteries but not both together. Additionally a PV panel charges through a single output PWM to the house bank. I want my starter battery to charge when off grid. A simple fix would be a trickle charge from a 12V stand by charger wired between house and starter battery.
However, I’ll be replacing the FLA house batteries with LifePO4. I’m told that a charger like this will only work FLA to FLA. Example: Votronic 12V StandBy charger. I could fit a dual output solar controller, but prefer Victron build and 5 year warranty. Victron solar controllers don’t have dual output.
As mentioned, I won’t be stripping out an old van and intend selective upgrades as follows:
Victron Superpack 12.8V LifePO4 100Ah x 3
PV panels: 100watt x 3
Victron BlueSolar MPPT 100V/30A
Sterling B2B Pro Batt Ultra 12V DC/DC 60amp
Victron BMV-700
What is the best way to charge my FLA starter battery? With that sorted, I think I’m ready for ordering the bits and having it wired up. I’m no expert, so if anyone sees errors or improvements please let me know.
