Hey guys, long story short I did two lithium conversions this year. One for my car which is an animal and one for my friends 2014 E4 which he managed to kill…(please dont ask). I need to get him up and running and I’m thinking about going back to flooded batteries but adding a 7th battery.

Plan is to run 7 Trojan 1275’s with and replace his delta q with this model and profile 13.

I’m just a little confused with how to set this charger up with the PSDM J4 and the cars interlock. Any help would be great before I start ordering parts. Thanks!
