On this wire, you’ll need to install a momentary push-button switch attached with two spade connectors. From these studs, you’ll run a wire to both your house battery bank (Batt Coach) and your Starting Battery (Batt Chassis). You’ll need a 5/16” lug to connect these wires to the Li-BIM.
They both charge and maintain similar voltage. After replacing the coach batteries with lithium, the coach and chassis will charge and maintain voltage at different rates. The BIM should be replaced with a lithium-compatible battery isolation manager to properly charge both sets of batteries and not overwork the RVs alternator.
The last part of my upgrade was to install a lithium-compatible BIM or Battery isolation manager. A BIM is a device that allows both the RV's coach batteries and chassis battery to stay charged. It does this by monitoring the voltage of both sets of batteries and allowing charging power to the specific battery as needed.
This is typically between two banks (the chassis and coach), of lead-acid batteries. They both charge and maintain similar voltage. After replacing the coach batteries with lithium, the coach and chassis will charge and maintain voltage at different rates.
When attached to shore (120v) power, if it senses the chassis battery is low it will allow the RVs charger/converter to charge the chassis battery. In turn, when the RV is running and it senses the coach batteries are low it will allow the alternator to charge the coach batteries.
