Depending on your battery size, you probably can not charge the battery at more than 40 amps for more than a few minutes.
You don't say the SOC of the bank when starting the 40a charge.
You're right about that - I've never been below 60% and am almost always > 80% (will probably change once it starts getting cold).
Is that all test data on your graph, or is that curve a published curve? Very helpful.
Actuals using 35a Vector portable chargers (two for the 70, 35 +20 for the 55)
these are programmed to trip at 14v so the amps taper but the voltage keeps rising to 14.6v with that 14v trip point, the SOC will be a little lower than with a charger you set to reach 14.6 and then it holds, but not much different.
Here is a comparison of the Vector profile with a PowerMax modified set to reach and stay at 14.6 to see the difference in outcome. Vector trips at 68% vs 72% but still gets there.
