lithium ion
Background. If li-ion cells are arrayed (series x parallel — S x P or P x S) to form a battery, it is generally recommended to manage parallel stacks of series cells (P x S) independently, such that each individual stack may be managed with an independent BMS, as depicted below.. This is because a typical BMS IC will assume that all parallel …
Charging Li-ion batteries in parallel
The battery itself (3.7V, 650mAh) comes with its own PCB with Schottky diode and current regulators as protection. EDIT: Not a Schottky diode. Current limiter and a Protection IC. By design, they work together just fine. I have more batteries from the same manufacturer and wanted to make higher capacity packs by putting two cells in parallel.
