Hi,
If I use 26650 LiPos with protection circuits built in, and charge them all independently, can I connect four of them up together?
The output will be through a buck converter, so it doesn't matter to me whether they are best as 2S2P or 4S (or 4P with a boost).
Am I right in thinking that series is safer then parallel?
Do built in "protection circuits" all do the same thing?
Thanks
Jim
