Imax b6ac

I would like some help configuring my new charger.

I dont know anything about A, mah etc.

I have 2 lots x 5 batteries each hooked up together, in series I have been told, and on the pack it says 10 x SC2500mah 12v

My question is what is the max power I set my charger at to rapid charge my batteries?

The original charger that came with the RC Car says the charger has 800mah on it.

If I set the new charger to 0.8A, will it take the same amount of time to charge? If I then double the A figure, will that then halve the charging time?

Please help thanks

Is it a NiMH pack? Any pictures of the pack, it sounds weird from the description.

Doubling the current will roughly cut the charge time in half, but you have to be careful that you can charge the pack at that current rate. Generally you don't want to exceed 1C. C is the capacity of the pack, in amps. For you, this would mean charging at 2.5a max (2500mah = 2.5a).

SO i can set it up to deliver 2.5 amps and charge it?

Does it (the charger) switch off automatically when it is done?

Yes it is Ni-Mh

How about discharge rates? What figures should I put in for the range of the current charge and range of the final voltage?

WOuld final voltage be 12V as my battery is a 12V?

Yes, and yes to charging.

The charger should automatically handle charging and discharging as long as you give it the rates.

Go as high as the charger will let you, it won't be very high on that charger.

OK so Ive charged my battery with the new charger. After 50mins it says Battery full and the final reading was that the battery had 1152Mah.

I thought my batt was 2500mah? The batt is only like 4 weeks old.

What is happening??

Was it fully discharged before you started? If it was only half discharged, you'll only get half the capacity back in.

It might've been a false peak, I typically run a second charge cycle on nicad or nimh packs to make sure they're fully charged.

I went to discharge the battery and it shut down after 4hrs and the display read 1300mah. why did it shut down before it reached 2500mah?

I believe so.

I had set the battery to discharge and when it finished, it had a figure of 1300mah
