How to charge Turnigy AA LSD 2200mah Low Self Discharge Cells


Here i took pics of batteries, wall charger and Transmitter battery Holder.
The specs of cells are AA
There are 8 cells all are 1.2 V
5 cells are 2000 mah and 3 are 2500 mah

The pics of cell are





The Pics of Wall charger are





The Transmitter i am using is
Hobby King 2.4Ghz 6Ch Tx & Rx V2 (Mode 2) http://www.hobbyking.com/hobbyking/s...idProduct=9042
The pic of battery holder of transmitter is



As you can see the transmitter specs says 1.5 v However i have cells of 1.2 V.
8 cells x 1.5 V = 12 V
8 cells x 1.2 v = 9.6 V

As you can see the wall charger pics. Its output is 12 v which is higher than 9.6 V

If i connect it with transmitter charger port will it dangerous? I dont wana take risk

You shouldnt be mixing and matching different cell types or capacities, grab 8 matched cells and you can charge them

A fully charged AA cell is around 1.45 - 1.5v when full (making the 12v charger ok to use)

It's safer to charge them seperately outside of the TX but plenty do it with no issue, including myself

Cheers

Purchase 8 each AA NiMH cells (batteries) place them i your transmitter and charge them withg a stsndard RC Transmitter / Receiver charger such as comes standard with most RC systems.

The Sanyo Eneloop AA low self discharge batteries are perhaps the best but others will work also. Best to not use ones with greater than 2300 mAh capacity however.

If you are charging AA/AAA on a consistent basis then something like the La Crosse BC-900/BC-700 or the Maha C9000 charger is a great investment. The two main benefits of these chargers is they charge each cell individually and they can cycle the cells. When charging my transmitter batteries each week I set them to discharge first and the automatically charge. This prevents any memory effect that you will see with something like a wall wart charger or the $10 AA/AAA chargers. I personally have 2 of the La Crosse units so I can charge 8 batteries at once.

Now with that said you should always have a wall wart charger in your box so you can easily charge at the field/race track if needed.
