Description
SMART ACTIVE BALANCER 24S 4A (JK-B4A24S) (1a35)
The JK-B2A24S is a smart active balancing equalizer designed for large lithium battery packs (up to 24 series cells, e.g., ~72 V nominal). It actively redistributes energy between cells to keep voltages tightly matched, improving battery performance, capacity usage, and cycle life. It’s particularly useful for solar storage, e-vehicles, inverters, and DIY battery systems.
⚙️ Key Features
- Supports 2S–24S battery packs: Works with packs from 2 up to 24 cells in series — suitable for 24S systems (~72 V) and can even be cascaded for higher cell counts.
- Active balancing: Uses energy transfer technology rather than passive bleed resistors, balancing cells more efficiently and with less wasted heat.
- Up to 2 A balancing current: Adjustable between ~0.1 A and 2 A for faster equalization compared to typical passive balancers.
- Bluetooth monitoring: Built-in Bluetooth enables connection to a smartphone (Android, iOS, HarmonyOS) to view real-time cell voltages and module status.
- Accurate voltage acquisition: Monitors each cell with high precision (±3 mV typical).
- Self-powered: Uses the battery pack itself as the power source (40 V – 100 V operating range).
- Cascade support: Can be linked with additional units to balance packs with more than 24 cells in series.
- Robust & safe: Includes equilibrium line resistance diagnostics and protections to prevent damage in abnormal conditions.
More Info
🧠 How It Works
This active balancer continuously monitors each cell in your multi-cell lithium pack. When it detects a voltage difference between cells, it actively transfers charge from higher-voltage cells to lower-voltage ones. The result is faster and more efficient balancing compared with traditional passive balancers, which waste energy as heat.
💡 Why Use a 4 A Active Balancer?
✔ Faster balancing on large packs (24S) – ideal for heavy use cases.
✔ Broad battery chemistry compatibility (LiFePO4, Li-ion, LTO).
✔ Real-time app monitoring helps catch problems early.
✔ Helps extend cycle life and maximize usable capacity.
