battery charging issues

right, ive now got the whole battery made up so its a 24v 20-cell Nimh pack. However, the constellation's discharge limit is 3 amps but when ive tried to discharge the newly-wired pack for the first time as a 24v pack, its jumping to 5.06 amps and the heat sink is actually getting colder due to the fan kicking in?! any help?! its currently discharging on the Nimh auto mode

The 7.2v pack is no longer charging or discharging (won't move from 8.1v?!) and the 16.8v pack is discharging very very slowly. I guess this means the 7.2v pack is dead and the 16.8v is damaged?

or your charger is nackered. Got another charger to hand or a friend with one nearby?

**Danjr1** · 3rd July 2011, 21:34

Nope. Any other ways of checking?

As a last resort you could send them to someone to check them over for you?

Well I'm guessing if a charger rated up to 3 amps jumped upto 5 amps when discharging, it's probably broken the charger! Can't understand why it would do it though. However, getting some to check the batteries would be cool.
