Will the Redarc In-Vehicle BCDC Battery Charger Work w/ My Tundra's 130 Amp Alternator?

Question:

Instructions state to connect input to vehicle battery and not the alternator. My concern is that when 40amps is being pulled directly from the battery, can the vehicles charging current keep up? Just because there is a 130amp alternator does not mean that its all available at the battery terminals. Thanks 2010 Tundra with a travel trailer

The 130 amp alternator in your 2014 Toyota Tundra is definitely high enough for the Redarc In-Vehicle BCDC Battery Charger - Dual Input - DC to DC - 12V/24V - 40 Amp item # 331-BCDC1240D. I reached out to my contact at Redarc and he said that almost half of your alternator power will be able to switch over to their charger systems.

You are going to need a fuse kit. I recommend the 60-Amp MIDI Fuse Kit for Redarc In-Vehicle 40-Amp BCDC Battery Charger item # 331-FK60.
