Hi guys!

when i bought my monster, there was 2 battery packs with it, a carson 3000mah, and a standard panasonic something cheap.

The carson battery is new, but it has never been charged before, I have a RC-Power BC6 charger(i dunno if im wrong, but this charger have it all, 220 volt powersupply, connection to a car battery if i want to, usb connection so i can watch battery status, charges Lipo, life, nicd, nimh and so on)

I set the charger to 6 volt @ 0.2 amps but when it reaches 500 mah, it tells me its full :S

then i run some cyckles on it, 10 actually, and it didnt help.

whats wrong with my batterypack

BTW: i have ordered a brand new 4600ma 5 cell 6 volt pack, how should i charge it the first few times.

sorry for my bad english, im a dane:balloon:

Try charging it at 3a for 1 hr and see what happens. 0.2a is too low IMO.

Does it charge your other battery packs ok? Do you have another charger you can try or maybe borrow 1 from somewhere?

don't set it to 6 volts. the charger will drop the amps to zero every few minutes and test if its full. its cutting off because it wants to go over 6 volts but the cut of is stopping it.

when my battery is charged it registers over 7.2 volts.

Think you've got it there.
Simple chargers always charge 6V batteries with 7V or 7.5V.

charge voltage should allways be about 10% over that of the battery. can go higher, but you have to be careful that you don't overheat it

keep in mind that when under load the charger will show a voltage higher than what the battery is actually sitting on. if your concerned about the battery set the charger to 7.5 volts and charge. I charged a brand new 4600mah battery last night, had no cut off set but did set it to 0.8 amps rate and the battery took 5400 mah before it said it was full and was around 7.2 volts

my charger goes to 7.7volt sometimes.
