OC,
You raised (3) questions from recharging in-the-field.
1) What temp do let them cool back down to or how long do you wait before re-charging packs in-the-field?
1a) Do you still use the 120F rule when re-charging?
2) What charge rate do you use?
3) Probably insignificant, if you use 5-6A for the re-charge, is there a significant loss in drive duration? From like 7min down to 6 min?

Thanks
