deltamike said:Hi Mikey,
Bit of a puzzler but easily solved with trial and error.
First of all, something is not right. (Genius - aren't I) :lol:
Charge the 4000 and then take a voltage reading. Straight after a charge it should read about 12.75v. After two days or so it should read about 12.60v and if both are drastically lower then the battery or the charger is knackered. (Technical phrase)
Also, I would try a flight with a 2200. Take a voltage reading before flight one, and time the duration - then charge the SAME battery - let it rest till the same voltage reading is obtained (Might take a day or so) - and test the duration again and fly in exactly the same conditions. If you do this and the duration is shorter than flight one, then your charger is at fault and not charging the battery up enough. You can probably discount a faulty battery.
The flying conditions MUST be calm to do the above tests and do not change any settings between the two flights.
Speaking of chargers, the Core UAC-50 is brilliant. It tells you if a cell is knackered - what the voltages are - balances the voltages - and many other things. It also charges Ni-Cads and others. It may be pricey but it WILL keep your batteries in peak condition.
Try the above and report back.
