BMS 13S 48V 60A

Reliable 13S 48V 60A BMS (Battery Management System) for Li-ion / Li-poly battery packs. The system balances cell voltages, provides discharge and overcharge protection, temperature control (if a sensor is used) and protects the battery from damaging modes – for longer life and greater safety.

Customization

• E-bikes, scooters, e-motorcycles, pushchairs
• 13S (48V nominal) Li-ion/LiPo battery packs
• Upgrades and DIY projects requiring up to 60A discharge

Main functions

• Balancing (13S): equalizes the voltages of groups of cells, reducing imbalance
• Protections: overload, over-discharge, short circuit, over-current
• Temperature control (with sensor): overheat/underheat protection
• Stable discharge up to 60A: reliable operation in higher power systems
• Low internal resistance: more efficient energy release, less heat

Specifications

• Chemistry: Li-ion / LiPo (13S)
• Rated voltage: 48 V (fully charged ~54.6 V, 13 × 4.2 V)
• Elements in the 13 series (13S)
• Max. Continuous discharge: 60 A
• Protection: overload, over-discharge, short-circuit, over-current
• Balancing function: available

Installation notes

• Follow the correct pinout (B-, P-, C-, B1…B13).
• Perform the first switch-on without load, checking the voltage of each group.
• Use cables of appropriate cross-section and good cooling.
• A fuse is recommended on the battery line according to the system current.
• If possible, install a temperature sensor at the cell core.

FAQ

Is this BMS suitable for 18650 and 21700 cells?
Yes, if the pack is 13S Li-ion/LiPo and the current/heat requirements are met.

Can I charge via the BMS?
Yes – use a CC/CV charger of the appropriate voltage (13S Li-ion ~54.6 V).

What is the difference between P- and C-?
On some models, P- (discharge) and C- (charge) may be separate – check the BMS diagram.
