[QUOTE="blisters, post: 250755, member: 4992"] Normally switch/relays will break the existing battery connection before connecting the other battery so there is a momentary loss of connectivity to both batteries in this case. I am not sure how the redarc would react in that situation if it is charging (it might actually handle it ok). If the ignition is off then it won't matter. Look for a SPDT relay for this purpose with the charger positive wire to the pole and the normally closed relay tab to your 80a battery positive and the normally open tab to your 120a battery positive. Bolt the charger ground wire to the chassis. Flick a nice led illuminated switch to engage the relay to disconnect the 80a and charge your 120a. The relay coil and switch should be wired from your ignition. Jon [/QUOTE]
