<snip>Most cycles to at least80%. DoD with well over 100 cycles to 3.0VPC /0%
<snip>Bulk charging is approx .38C (98% by alternator (rarely even turned solar on)
Pack still delivers slightly ovr400Ah 406.2 Ah on last capacity test
400 ah * .38 c = 152 amps
400 ah * .8 dod = 320 amps
If I understand correctly the bulk phase will be ~2 hours at ~150 amps.
What is the ambient temperature range that your cells live in?
Do you have any data on the cell temperature change during charge?
Also, have you measured alternator ripple?
