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.
