BMS 14S 52V 20A

BMS 14S 52V 20A – Battery Protection and Balancing Module

Reliable 14S (52V) lithium battery protection and balance. This BMS (Battery Management System) is designed for 14S packs (nominal class 52 V ) up to 20 A current. Provides discharge and overcharge protection, balances cell groups for longer battery life and safer operation.

Why choose

• Protection circuit: overload, over-discharge, short-circuit and over-current (optional).
• Balancing: balances groups of 14 elements, reducing voltage differences and imbalances.
• Longevity: more constant temperature and more uniform cells = more cycles.
• Universal application: e-bikes, e-scooters and other 52 V systems.

Compatibility

• Chemistry: lithium/lithium
• Configuration: 14S (Class 52 V)
• Current: up to 20 A DC.

Specifications

• Type: BMS 14S 52V 20A
• Protection: discharge/overload;
• Balancing: passive (typical)
• Installation: into the battery pack according to the diagram (qualified installer recommended)

Benefits in real use

• Safety: reduced risk of thermal damage during incorrect use.
• Capacity maintenance: balanced groups make better use of the full package.
• Reliability: automatic disconnection when limits are exceeded.

FAQ

Will this BMS fit my 52 V (14S) battery?
Yes, if your pack is in 14S configuration and requires up to 20 A of current.

Can it be used with loads greater than 20 A?
No – choose a higher current BMS if the system requires more than 20 A.

Does the BMS balance during loading or also during unloading?
Passive balancing is usually done during loading;
