Charging / Balancing 2 LiPo batteries in series as 1

[@rabo4ii]

Cabobila, the battery on the negative plugs into regular 3s balancing port (4pins). The battery on the positive goes to the left hand side of 6s ballancing port (6 pins) then charge as 6s battery (for setting up charger refer to manual)

Really good Video. It works perfect. Don't buy a multiple lipo charger !!!!!

Hi RCgloves, I am an novice in this so to charge in series 2x 2.2a 11.1v 3S what would be the configuration? On the negative(black) I should plug it in the normal 3pin and on the positive(red) I should plug it in the left(last 3) pins of the, say, 5 pins socket. Is this correct? Also, how do I progaram the charger? 6 cells 22.2V? Thanks for the video....

so. to connect 2x 4s batteries in series to a balance port i need to connect the one with the negative plug to the normal 4s balance port and the one with the positive plug to the left of the 8s balance port?

amazing...tnx a lot

If you make a mistake with the balance leads what could happen?

Awesome

Hi, let's say that I need to use two batteries together (f.e. one 2s1p and one 3s1p). The question is, can I connect the two batteries balanced wires with only one JST-XH plug ? What I mean is, can I the three wires (from the two cells battery) and the four wires (from the three cells battery) together in one six channel JST-XH plug connect? So it is so much easier ... Thanks

What about 2 batteries with different mah?

[@ChuddleBuggy]

The lower capacity (less mah) battery will overcharge while the higher capacity will under-charge. Assuming both batteries are rated at the same voltage, the lower capacity battery will reach full charge sooner, which then causes it to offer higher resistance to the charging current. Higher resistance will cause the voltage drop across it to go higher as well, thus forcing it to charge higher than intended. Meanwhile, the overall current across both batteries in series will have decreased, thus dropping the voltage across the Higher Capacity battery, consequently delaying it's charge time and decreasing the charging voltage across it at the same time.
