BMS 10S 36V 30A

BMS 10S 36V 30A – reliable battery protection and balancing module for 10S (36V nominal voltage) Li-ion/Li-poly packs. Protects against overcharging, over-discharging, short-circuiting, over-current, balances cell voltages and helps to extend battery life.

Main functions

• Protection circuit: overload and over-discharge, short circuit, over-current.
• Balancing: maintains the voltage balance of 10 cell groups (10S) during charging.
• Up to 30 A discharge current*: suitable for most 36 V e-bikes, scooters, DIY projects.
• Temperature and polarity control: standard protection is provided (version dependent).

Compatibility

• Chemistry: Li-ion/Li-poly 10S (10 series bonded groups).
• Nominal voltage: ~36V (fully charged to ~42.0 V).
• Use: e-bike, e-scooter, other 36V projects.

Specifications

• Configuration: 10S (10×3.6 V)
• Nominal voltage: 36 V
• Max. Charging voltage (package) : 42.0 V
• Max. continuous discharge : up to 30 A
• Protection: overload / over discharge / over current
• Balancing: passive (typical), balancing current depends on version

Installation and notes

• Use the correct wiring diagram (B-, P-/C-, balancing wire sequence B1-B10).
• First connect the balancing wires according to the sequence of elements, then the main terminals.
• Avoid short-circuiting and use cables with a sufficient cross-section.
• It is recommended to integrate a fuse and comply with IP and cooling requirements.
