I’m thinking about my battery pack and I’m not quite sure what to do. I want to go with 8S voltage and now thinking about choosing 2 packs of 4S 5Ah 30C in series or better 4 packs of 2S 2,5Ah 30C. The price is the same, but the 4 pack option has a quite better form factor because of the flat shape of the 2S. For charging I’d put 2 2S in series and charge them like a 4S.
Are there any disadvantages of going 4 packs of 2S in series? Actually I’d get 4x 2S with 3,2Ah each for the same price as 2x 4S, so 2,8Ah more. But for me the technical aspects prevail.
Thanks for your help!
