Dongguan Jinfen Electronics Co., Ltd., a global leader in smart battery management systems (BMS) and IoT applications, today officially announced the commercial availability of its next-generation JNFN-24APA 2.5A Active Balancing Smart BMS. Engineered for light electric vehicles (LEVs), residential energy storage systems (ESS), portable power stations, and industrial battery packs, the ANT-24APA sets a new benchmark in active cell management, multi-chemistry adaptability, and overall system longevity.

⚡ 1. Overcoming Industry Bottlenecks: Active Energy Transfer vs. Passive Heat Loss

During long-term operation of multi-cell battery packs, inconsistencies in internal resistance, self-discharge rates, and ambient thermal gradients inevitably cause cell voltage divergence. Traditional passive balancing relies on resistive bleed-off to dissipate excess energy as heat. This method suffers from low balancing current (typically tens of milliamperes), severe thermal buildup, and wasted energy.

The JNFN-24APA breaks this bottleneck by adopting an advanced transformer-based active balancing topology capable of delivering up to 2.5A (2,500mA) of balancing current. By dynamically routing energy directly from higher-voltage cells to lower-voltage cells without resistive dissipation, the system achieves millivolt-level cell equilibrium during charging and discharge cycles, significantly extending battery cycle life and usable range.

🔲 2. Precision Engineering & Universal Multi-Chemistry Support

Designed as a highly versatile solution for global OEMs and system integrators, the JNFN-24APA delivers top-tier performance across key hardware metrics:

• ✓ Universal Chemistry Compatibility: Fully compatible with Lithium Iron Phosphate (LiFePO4 / LFP), Ternary Lithium (NMC), Lithium Titanate (LTO), and emerging Sodium-ion (Na-ion) chemistries across a 24V–96V operating range.

• ✓ Flexible Cell Configurations: Configurable from 13S to 24S cell series (13S–21S for NMC; 13S–24S for LFP, LTO, and Na-ion).

• ✓ ±3mV High-Precision Sampling: Powered by Nations Tech industrial-grade MCU and AFE silicon, achieving ±3mV cell voltage measurement accuracy and ±2% current sensing precision. Dynamic sampling rate switches automatically between 1Hz during balancing and 4Hz in idle states.

• ✓ Ultra-Low Power Draw: Consumes <1.5mA during operation and <0.6mA in standby mode, preventing battery drain during long-term storage.

📶 3. Smart Connectivity, Ecosystem Integration & Low-Temp Heating

More than a protective circuit, the JNFN-24APA functions as the intelligent nerve center of the battery system:

• Comprehensive Connectivity: Includes onboard Bluetooth 4.0 and RS485 as standard, with optional CAN, TTL, GPS, and DI/DO digital control signals for seamless integration into vehicle dashboards, telemetry units, and cloud IoT platforms.

• Integrated Smart Heating: Tailored for cold-climate operation, automatically triggering external heating pads during low-temperature charging. Features over-temperature shutdown and real-time app alert protection.

Users and fleet operators can monitor real-time State of Charge (SOC), State of Health (SOH), individual cell voltage spreads, and temperature sensors via the ANT BMS V2 App (iOS/Android) or WeChat Mini-Program. Tiered password protection prevents unauthorized parameter modification.

🛡️ 4. Multi-Layer Safety Protections & Available Model Variants

Safety remains paramount. The JNFN-24APA incorporates over 15 hardware and software protection mechanisms, including two-stage overvoltage/undervoltage cutoff, MOSFET thermal shutdown, cell high/low-temperature protection, short-circuit protection, two-stage discharge overcurrent limits, wire disconnection sensing, and an onboard high-decibel buzzer alert.

💬 “The JNFN-24APA is our flagship answer to the market's demand for high-durability, high-efficiency battery packs. Transformer-based active balancing eliminates the bottleneck of weak cells, ensuring every watt-hour is utilized efficiently over thousands of cycles.”
