2004 Cat C7 Charging LifePo4 battery bank
I am upgrading my battery bank to a hell of a lot of capacity (Around 1200 amps). I know that if this was a gasser, the alternator will die young if it has to charge the bank. How good is the alternat...

Map40,
I wish I could help more, but I am currently still in the research phase for a client. There are available DC-DC chargers that both create the correct final voltage for charging LiFePo4 batteries and limit the charge current drawn from the source. It is a single unit. There also should be a BMS Battery Management System with the Li unit to keep it from hurting itself or others. As said, this is a study in process on my part.

Thanks for the reply Matt. I got that part covered. The batteries are managed by their own BMS which can charge them dirvectly from the alternator feed. All of that works and so far I have 340 amps installed and they work great. My concern is: Will the alternator take the workload? The old Lead acid setup was 300 amps to recharge in the worst case, but when you talk about 1200 amps, the alternator will NEVER rest. Wil it last?
