BMS 16S 60V 40A

Reliable for 16S 60V 40A BMS lithium battery packs (18650/21700 Li-ion/LiPo; for LiFePO4 check voltage thresholds). One C-port – charging and discharging takes place on the same socket, making installation simpler and tidier.

What is it for?

• For electric bikes, scooters, go-karts, light EVs and DIY power packs.
• 16S Li-ion (nominal ~59.2 V, fully charged ~67.2 V) for systems up to 40 A continuous discharge (≈ 2 kW class; peak according to datasheet).

Key benefits

• Common port C: fewer wires, fewer connection errors, easier diagnostics.
• All necessary protections: overload, deep discharge, overcurrent, short circuit
• Balancing: ensures more uniform cell voltage and longer acupack life.
• Stable 40 A load: enough for everyday use and steeper climbs.

How to connect (summary)

• B- → directly to the battery – terminal.
• C- → common point of the charger (-) and controller/motor (-).
• B(+)/system(+) → usually directly from the acupoint to the system (follow the diagram).
• Balancing bar (B1…B16) → connect in strict sequence to each cell node.

Specifications

• Chemistry: 16S Li-ion / LiPo (LiFePO4 – only if BMS thresholds are adapted; LiFePO4 16S full ~58.4 V).
• System: class 60 V (Li-ion full 67.2 V).
• Max. DC discharge: 40 A (instantaneous peak – according to the specific model sheet).
• Balancing: passive (typically 30-100 mA, depending on version).
• Contacts: contacts B-, C- (common), balancing connector.
• Operating temperature: ~-20…60 °C (refer to sticker/datasheet).

Safety and usage tips

• Use a charger with the appropriate chemistry: 16S Li-ion 67.2 V CC/CV.
• Strictly follow the sequence of the balancing wires – mistakes can damage the BMS or the acupoint.
• Ensure ventilation and isolation from vibration/humidity.
• If the controller requires high peak currents, choose a higher A BMS.

FAQ

Can I load and drive at the same time?
Technologically, yes, it is possible.

Why is there no P- terminal?
This model has a shared C-, so a separate P- is not provided – simplifying installation.
