Charging multiple packs at Once!

          First off you have to have a good charger capable of charging the number of cells you want to charge. I use an AstroFlight112D, it will charge from 1-36 cells at a 5amp rate. The following picture is a harness I made from deans connectors so that I could charge 4 packs at the same time. Its very easy to make something like this. The harness is wired in series. Which means that the harness wires go from positive to negative.

          The jumpers are used when I am charging less then 4 packs. The "jumper" takes place of the missing pack.

           We now sell the "Y" harness needed to charge and use 2 packs.

Important things to remember.

Only try to charge packs of the same quality, brand, capacity(mah) and age. For example, don't charge a 3000mah pack with a 3300mah pack. Don't charge a new gp3300mah pack with a gp3300mah pack that's a year old. Don't charge a Gold Peak 3300mah pack with a pack of 3300mah cells from a different company. Also packs should be drained to the same level before charging or this charging method will cause false peaks and the packs wont equally charge.

This method is a quick way to charge all those cells in different packs, but each individual pack should be re-peaked singly to assure maximum performance from your cells.

          Below is the harness that attaches to the motor controller. I epoxy two Deans connectors together. to keep the wire length to a minimum.

Below is a typical way to run two pack in series to a speed controller. If you run the wires in the same way you will double the voltage and the mAh will stay the same.

Just in case you were asking yourself why I used the stock Tamiya style plug with the deans plugs, it because all my packs come with deans and the Cen Boats come with the stock Tamiya style connector. I like to test the boats before I send them to customers.
