I have an Autotrail Motorhome with a Sargent Electrical unit that used to provide split charging for my Leisure and Starter batteries.
Last year I had installed the following system:
200amh LifePo4 Victron battery
Multiplus 3kva inverter charger
Victron BMS
Victron BMV712
Victron 200watt Solar Panel AND a SmartSolar 75/15 MPPT Charge Controller
Victron SmartSolar 75/10 MPPT for the original 100watt solar panel (removed the PWM charge controller and bypassed the Sargent Unit)
Battery Protect on the "output" side of the battery / system
Battery Protect between a Sterling Power DC-DC battery charger and Lithium battery
(Sterling charger runs of the starter battery / Alternator while the engine is running)
MY QUESTION IS:
Can I introduce a "Split Charger" between the once of my MPPT Charge Controllers and my starter battery using the cables already in place (or new cables)?
Which Victron unit would I need? (Cyrix...?)
Thanks in advance
Steve
