only thing more to say on top of the spot on advice given is give some consideration to getting the 10 s if you can afford it as machasm said ,this charger will see you for right for the future larger heli batteries.

Out of interest...how do you know when the battery is down to 20%?

The cellpro chargers tell you. But the best way to ensure you are not discharging to lower than the 20% is do the following:

CALC Pack capacity 2100 - 20% = 1680ma

1. From full charge fly your pack for a period of time you KNOW will not over discharge it, say 4 mins.
2. Charge the pack and note how many milliamps you put back in. You would be looking at 1680ma or less. Any more and you have used too much out of your pack and could damage it if you use too much more.
3. Each cycle extend your flight time until you reach approx 1600ma and thats your flight time for the pack.

If you do this you will ensure that maximum life and performance out of your pack. Remember always use your timer on the TX
