Product Overview
The JK-B2A24S RS485 adds wired system integration to the 2A active-balancer platform. Alongside Bluetooth app monitoring, an RS485 port lets the balancer report into host controllers, BMS units, and energy management systems — a must for commercial and industrial installations.
The balancing core is unchanged: supercapacitor energy transfer at up to 2A, current independent of voltage delta, ±3mV acquisition accuracy, and post-balance spreads within 3mV. It self-powers from 40–100V and cascades for strings beyond 24S.
Core Features
- 2A Energy-Transfer Balancing: Supercapacitor-based balancing moves up to 2A between cells with no heat waste and no dependence on voltage delta.
- RS485 System Integration: A wired RS485 link alongside Bluetooth feeds balance data into host controllers and energy management systems.
- ≤3mV Post-Balance Accuracy: ±3mV acquisition precision holds finished packs within a 3mV cell spread.
- Wire Resistance Detection: Balance-lead resistance checks catch loose or corroded contacts before they become failures.
- Bluetooth App Control: Real-time monitoring and parameter setup from a mobile app, with low-voltage shutdown guarding the pack.
- Cascadable Design: Link multiple units to cover battery strings over 24S without changing the setup workflow.
Application Scenarios
Designed for integrated systems, the JK-B2A24S RS485 suits 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-B2A24S RS485 replace my BMS?
No. The JK-B2A24S 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-B2A24S RS485 focuses on keeping every cell at the same voltage.
What is the balancing current of the JK-B2A24S RS485?
The JK-B2A24S RS485 balances at up to 2A, 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-B2A24S RS485 work with fewer than 24 cells?
Yes. The JK-B2A24S 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.
