Planning a battery pack

The original listing describes use in power storage and in multi-cell series or parallel configurations. If you are building a pack, check that the cells, charger and battery-management protection suit the intended voltage and current. Actual runtime, cycle life and discharge capability depend on operating conditions; confirm critical limits with the cell's manufacturer datasheet before designing a high-current pack.
