Core Technology Advantages

All JIKONG BMS products are built on our proprietary energy transfer active balancing architecture, with four core technical strengths:

• Bidirectional Lossless Active Balancing: Transfers energy directly from high-voltage cells to low-voltage cells without resistive heat loss, improving overall battery efficiency by 95%, maximizing pack consistency, extending driving range and prolonging battery cycle life.
• High Precision Voltage Sampling: Single cell detection range covers 1V to 5V with ±3mV accuracy, ensuring reliable monitoring and precise protection trigger points.
• Full Multi-Layer Protection System: Integrated overvoltage, undervoltage, overcurrent, short circuit, over-temperature and low-temperature protection, plus MOS overheat detection, eliminating potential safety hazards in all scenarios.
• Flexible Expansion & Compatibility: Standard Bluetooth support for Android, iOS and HarmonyOS mobile control; optional RS485, CAN, GPS and heating modules for different application needs; fully compatible with ternary lithium, lithium iron phosphate, lithium titanate and manganese acid battery chemistries.

1. Active Balancing Integrated BMS Series

This is our core product line, with protection, balancing and monitoring functions integrated on a single board, suitable for finished battery pack assembly and mass production.

Low Voltage Small Current Series (3~8S, 7.5V-36V)

Typical models include JK-BD4A8S-4P, JK-B2A8S-20P and JK-B2A8S-30P, with balancing current ranging from 0.4A to 2A and continuous discharge current from 40A to 300A. This series features compact size, ultra-low standby power consumption and optional heating function, making it ideal for small electric vehicles, electric scooters, motorcycle starting batteries and small portable power stations.

Medium Current E-Mobility Series (7~24S, 20V-100V)

Typical models include JK-BD4A17S-4P, JK-BD4A24S-6P and JK-BD6A24S-10P, with 0.4A to 0.6A balancing current and 40A to 120A continuous discharge capacity. Built-in coulomb meter delivers accurate SOC calculation, and parallel connection is supported for higher capacity. It is widely used in electric motorcycles, electric tricycles, sightseeing buses and small electric forklifts, with optional GPS for remote fleet management.

High Current Low Speed Vehicle Series (7~24S, 20V-120V)

Typical models include JK-B2A20S-20P, JK-B2A24S-30P and JK-BD6A24S-15P, equipped with low internal resistance high-power MOS, supporting 150A to 300A continuous discharge and up to 600A peak current. Balancing current reaches 0.6A to 2A for fast consistency recovery. This series fits low-speed electric vehicles, heavy forklifts, large commercial energy storage systems and tower battery swap scenarios.

Home & RV Energy Storage Series (3~16S, 7.5V-70V)

Including PB series home energy storage models and RV dedicated models (100A/200A/300A), this line features isolated power supply circuit, 4-channel temperature detection and parallel current limiting function, fully compatible with common solar inverters. It is the preferred solution for off-grid solar energy storage, caravan house batteries and residential backup power systems.

Starting Battery Special Series (3~8S, 7.5V-40V)

Represented by JK-QB2A8S-20P, this model adopts ultra-low internal resistance design, with 2A balancing current, 200A continuous discharge and 3000A instant starting current, specially developed for motorcycle, passenger car and engineering vehicle starting battery packs.

Relay Type Ultra-High Current BMS (3~25S, 16V-100V)

The JK-B2A25S-RP model works with external high-power relays to support up to 500A continuous operation. It has extremely low standby power consumption of only 20mW in shutdown mode, and is suitable for heavy engineering vehicles, base station backup power, large industrial energy storage and other high-power scenarios.

2. Standalone Active Balancing Module Series

Independent balancing modules designed for existing battery pack upgrade and maintenance, no need to replace the original protection board.

Typical models cover DZ08B1A24S, DZ08B2A24S and 10A/15A high current versions, with balancing current from 1A to 15A that works independently of cell voltage difference. It supports cascade connection for battery packs with more than 24 cells, and auto-balancing triggers when voltage difference exceeds 4mV with adjustable threshold. Built-in Bluetooth allows real-time cell voltage monitoring via mobile APP. This series is widely used for old battery pack repair, battery consistency maintenance and industrial energy storage system balancing upgrade.

3. Voltage Difference Balancing Instrument Series

Handheld professional balancing tools for battery factories, after-sales service teams and maintenance personnel.

5A24S Balancing Instrument

Adjustable balancing current from 0.8A to 5A, supports 2~24 series battery packs and can be cascaded for more strings. Built-in balancing wire resistance detection identifies wiring errors in advance. With portable toolbox design, it is suitable for on-site battery maintenance and daily consistency calibration.

15A24S Balancing Instrument

Adjustable balancing current from 0.8A to 15A, achieves ≤5mV cell voltage difference after full balancing. Compatible with all battery types including lithium-ion, LiFePO4, lead-acid and supercapacitors. It is ideal for battery pack factory aging tests and deep repair of severely aged battery packs.
