it's been years since I've done that in RC department.
Ok first of all you gotta remember I haven't had anthing to do with RC batteries since back in the day when a 1700mah pack was massive.
As I will be racing in 540 stock class I'm limited to 1500mah unmatched packs so to this end I purchased 7 Duratrak "shark" battery packs and even though cheap I think it's still a good idea to treat them right so have started to cycle them.
So the question is, is the following battery "behaviour" normal for the first one I've done....
Trickle charged for 17 hours resulting in a voltage reading of 8.46
Then pushed fast charge (4 amp setting) and the voltage shot up to 11 volts for a few seconds and then dropped to 10.5v
22 minutes later the fast charge switched off when the reading had dropped to 9.46v
At which time the reading then went back to the original 8.46 that it had been on when the battery had only been trickled for 17 hours.
The only thing any of this has in common from what I can remember of 1200 mah packs back in the day was that the battery got warm. But having never had a battery of even 1500mah I don't know whats normal for this size nowadays.
