Question:
Redarc In-Vehicle BCDC Battery Charger - Dual Input - DC to DC - 12V/24V - 25 Amp Item # 331-BCDC1225D I have a 2007 Dodge 2500. Is the 25 amp suitable for 100-200 ah battery or should I get the larger size to charge faster? Also is the larger 40 or 50 amp charger safe for my alternator?

Helpful Expert Reply:
The Redarc In-Vehicle BCDC Battery Charger - Dual Input part # 331-BCDC1225D will work fine to replenish the 200 amp hour battery but I do recommend to the use the Redarc In-Vehicle BCDC Battery Charger part # 331-BCDC1240D to replinesh the battery faster. The Redarc 40 amp charger is designed for battery banks 200 ah and higher and has a 600 watt power output. All of the Redarc chargers are safe for your system, the setup includes an effective battery isolation to prevent any feedback.
You will need part # 331-FK60 which are 60 amp fuses to protect both the starter battery and the auxiliary battery. I have attached a wiring diagram for your reference.
