Hi
I'm making a batterypack with 18650 cells. The voltage i need is 11,1 v (12v).
I was hoping that someone with more knolledge than me could take a look att my configuration and tell me if its right.
I have eight 18650 cells 2000 mAh. What capacity will this configuration give me?



Thank you

Welcome to AAC!

4000mAh. Two of the batteries in the group of 4 are extraneous.

 

4Ah @ 11.1V..

I'd invest in a good fire extinguisher if I were you.....................

 

I would say to not have uneven groupings of batteries. If you have 2 in parallel, do not then change to 4!
All groups need to be the same or Ian Field's comment it likely to be correct.

Probably not that dangerous if the TS adds a charge balancer board, but 2P combinations stacked in series with 4P stages; will discharge sooner and the current flow pushed by the other cells will try to reverse charge them. That can't be good!

 

How do you intend to charge them?

How do you intend to avoid over-charging or over-discharging individual cells?

Has the TS wandered off?
