Just out of curiosity, how does this resolve his problem.
There is a problem in Victim’s D4 and that needs to be addressed first.
My money is on a software issue with the D4’s BMS.
The SSB batteries are in use in hundreds of Traxide systems with very few problems occurring.
There are around 5,000 D3s, D4s, RRSs and L322s fitted with Traxide isolators, both here and around the world, and there are no such problems showing up.
So just spending heaps of money on a DC/DC device and a lithium battery could well be a very expensive fix that doesn’t fix anything and may well make the problem worse, particularly in relation to the cranking battery.
The problem needs to be sorted first, and if Victim still wants to charge to a lithium setup, so be it!
