LiFePo battery upgrade question
I ordered a 200AH LifePo battery to replace my two 100AH lead acid batteries and also a compatabile converter which takes care of charging the battery with shore or generator power but what about char...

If I can mount it in a plastic box safely I can keep the wires really short, 12-18", as the starter and house batteries are located very close to each other under the hood. Renogy recommendso 6ga from the starter battery up to 8' and a 60a fuse, and 8ga and a 50a fuse to the house battery.
If there is room--use a plastic battery box to hold the renogy. Make sure there is plenty of ventilation. dc to DC are not wonderfully efficient so the unit may need to dissipate over 250 watts of heat.
One minor concern. Is the starter battery flooded? If so the renogy should not be in the same compartment (corrosion will eat the renogy up). If the starter is AGM, then that's ok for the renogy to be in the same compartment.
I use auto reset circuit breakers rather than fuses.
I have dual 50amp charging paths (an attempt to improve charging before dc to DC devices were available). I've seen 70 amps--back in the old days when I had flooded house batteries (975 amp hours). I would use my inverter while running down the road and turn on the water heater. I used a duty cycle of 20 minutes on and 40 minutes off. I have manual control over the isolation solenoids.
