Product Overview
The JK-B1A24S RS485 combines 1A active balancing with wired RS485 communication for 2–24S packs. The RS485 port lets installers tie the balancer into larger monitoring networks, while Bluetooth keeps quick on-site checks one tap away.
Its supercapacitor shuttle moves up to 1A between cells regardless of voltage difference, holding finished packs within 3mV. The unit self-powers from 40–100V and can be cascaded past 24S.
Core Features
- 1A Energy-Transfer Balancing: Supercapacitor-based circuit shuttles up to 1A between cells — efficient equalization without resistor heat.
- RS485 System Integration: Wired RS485 reporting alongside Bluetooth for host controllers and energy management systems.
- ≤3mV Post-Balance Accuracy: ±3mV acquisition precision keeps finished packs within a 3mV spread for full usable capacity.
- Wire Resistance Detection: Balance-lead resistance checks flag poor contacts early, before they cause drift.
- Bluetooth App Control: Monitor cells live and adjust parameters from a mobile app; low-voltage shutdown protects the pack.
- Cascadable Design: Chain multiple units for battery strings over 24S with the same simple setup.
Application Scenarios
A practical pick for networked installations, the JK-B1A24S RS485 fits Small sightseeing cars, scooters, shared e-bikes, battery power systems, base station backup, solar power stations, and pack maintenance and repair.
Frequently Asked Questions
Does the JK-B1A24S RS485 replace my BMS?
No. The JK-B1A24S RS485 is a standalone active balancer that works alongside your existing BMS. The BMS keeps handling protection (over-charge, over-discharge, short circuit); the JK-B1A24S RS485 focuses on keeping every cell at the same voltage.
What is the balancing current of the JK-B1A24S RS485?
The JK-B1A24S RS485 balances at up to 1A, transferring energy from the strongest cells to the weakest ones. Higher balancing current means a large or badly imbalanced pack reaches equilibrium much faster.
Can the JK-B1A24S RS485 work with fewer than 24 cells?
Yes. The JK-B1A24S RS485 supports any pack from 2 to 24 cells in series. Unused balance leads are connected according to the wiring diagram included with the unit — if you are unsure, send us your pack layout and we will confirm the wiring.
