I know my 1C charge rate is 5.4amps and will take 1hr to charge or can charge at less amps and will take longer to charge...........
Correct on all the above

Common practice is to balanace charge each time because LiPo chargers can do that. Have mine hooked up each time but I do stop the charge when I see the charge amps start to drop away if the volatages are very close. I don't think the xtra time finishing the balance off gives any real advange unless the cells were miles apart in

3v is safe but higher is safer.

Your A.I. Brushless Pro has the following for voltage cut-off

AutoCell System: Ready for the next battery technology – LiPo batteries!
LRP’s exclusive and smart AutoCell System ensures that LiPo batteries can be used safely without accidentially deep-discharging of the cells. The motor function will be shut-off and the LED will flash if the system recognises very low battery voltage.


If you feel the car slowing just stop and go pick it up.

8.4v is the MAX voltage cut off for LiPo. At 12th Scale UK nationals I know they do a volatage check and anyone over the max charge voltage isn't allowed to race. They have to drop the voltage by discharging the battery a little before it can be used.
