Hi, I have a Ford E-350 camper cutaway with stock 130 amp alternator and 2 - 6V 220ah AGM batteries plus separator. If my engine battery goes dead I have switch I can hold and use the house batteries to jump start the engine battery.
I would like to be able to charge the house batteries much more quickly with the vehicle turned on but stationary, at idle in "Park". Of the three options below, would any or all work and what would be easiest solution? Would a high idle kit be necessary.
How do you account for batteries limiting charging capacity and getting them to take charges quicker?
I think my options are:
1. Second Alternator - I know ER and Provan Tiger use dual alternators to do this, but how is this setup, are both Alternators going to the house batteries or just one? Would second 130Amp work or higher end more Amp with better control charger built-in?
2. Upgrade to 200-300 amp single alternator - again would amps received by house batteries be limited, if so can this be mitigated?
3. B2B Charger - how realistic and easy, would I lose ability to start engine battery with house battery.
Thanks
