The scenario
An e-bike builder needs to wire a 6S4P Li-ion pack with a BMS to ensure safe charging and discharging.
What is in this drawing
Read the decisions behind it.
01
Choose series configuration first to achieve required voltage (6S gives ~22.2V nominal)
02
Parallel strings are connected at the ends to combine capacity
03
BMS balancing leads connect to each series junction to monitor and balance cell voltages
When constructing a multi-cell lithium battery pack for any electric vehicle, power tool, or energy storage system requiring precise voltage and capacity targeting.
