A lot of it depends on how it is currently wired. If you don't already have some outlets wired to the inverter it is usually easier to to get whole van on the inverter.

Normally, you would just...

Interesting way of doing it. Two separate chargers gives you a lot more options than using one and charging both batteries of it at the same time. I think a multibank charger would also work, but...

That is exactly why you need a current limiting B to B charger. If you didn't have the current limiting the acceptance of the AGM would be too high and draw too much current. It would be too much...

I think it will also give higher than 13.8v out if you set it that way, as they show 14.4v absorption, so near perfect if it does.

30 amp should be fine as it is current limiting so it can't hurt itself. The smaller size also allows you to select a lower amount of end amps to stop the charging.

It appears that the Kisae does...

Tiny little lithium battery showed up today. 3ah. It doesn't appear to have high acceptance of the larger lithium LiFePo4 that we are used to as it would not accept even 5 amps from the bench...

Sounds good to me. With the large lithium capacity than I am testing you will some extra options available, I think.

You could stop the AGM charging sooner in the recharge (lower SOC) as you will...

You would be able to charge each battery separately or together and also run off either battery when not charging, plus off of both.
