chuck has a really nice setup with his battleborns.

what he is saying is this.......if you have low starting batteries and use the merge function with LiOn batteries on the coach side AND immediately try and start your engine, the high current draw of the engine starter will make it highly likely you are going to blow the big fuses you have at your batteries or at your fuse block on the big battery cables. this is because the LiOn batteries will throw more current at it immediately than conventional batteries will.

i have used the merge function with my agm batteries many times with no issues.

those big round fuses on your batteries are typically 600a (at least that is what is on mine)
