Reliable for 14S 52V 60A BMS lithium battery packs (18650/21700 Li-ion/LiPo; check thresholds for LiFePO4). One C-port – charging and discharging takes place on the same socket, making installation simpler.
What is it for?
-
For electric bikes, scooters, go-karts, DIY power packs.
-
14S (nominal ~51.8 V, fully charged ~58.8 V Li-ion) for systems up to 60 A continuous discharge (suitable for projects in the 2-3 kW class; peak per datasheet).
Key benefits
- Higher current – 60 A: more stable traction, better start for hills and faster acceleration.
- One C port: the same downside for the charger and the controller – fewer wires, fewer bugs.
- Protections: overload, deep discharge, short circuit, overcurrent, over temperature* (*if NTC).
- Balancing: protects cell parallelism, increases longevity and capacity utilisation.
How to connect (summary)
- B- → directly to the battery -.
- C- → common point of the charger (-) and controller/motor (-).
- B(+)/system(+) → usually directly from the acupoint to the system (according to the diagram).
- Balancing bar (B1…B14) → connected in strict sequence to each element node.
Specifications
- Chemistry: 14S Li-ion / LiPo (LiFePO4 – only if voltage thresholds are matched).
- System: 52 V (full ~58.8 V Li-ion).
- Max. continuous discharge: 60 A
- 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
- Charge with 14S Li-ion charger ~58.8 V (CC/CV).
- Follow the sequence of the balancing wires – incorrect connections can damage the BMS.
- Ensure ventilation and isolation from vibration/humidity.
- If the controller requires >60 A peaks, choose a higher A BMS or double protection.
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 common C-, so a separate P- is not provided – simplifying installation.
