I am gradually inching my way up there. The alternator
puts out 100A at idle (200A alternator) and cruising RPM
it can charge up to about 170A now with the ground wire going to the lithium bank. Alas, the last tiny bit of current
eludes me since I can't connect the positive sense directly to the lithium bank (as things go nuts when the bank is disconnected). Nevertheless, I think that the alternator
is unlikely to supply more than 160A once it has reached operating temperature so I think this will be just fine.
Oh, I should also mention that the lithium bank was at 85% SOC so at a lower SOC, when I actually need to charge the bank, things should be even better.
