Eliminating Selection Fatigue: JNFN Active Balancing BMS All-Scenario Selection Guide

Introduction: Are you driving an electric tricycle heavily laden with goods and worried about battery power failure during steep climbs? Struggling with tightly constrained space in a battery pack where thermal dissipation must balance with cost control? Or perhaps you are operating a battery-swapping network plagued by data tampering, vandalism, and water ingress?

Whatever your scenario, the 3S to 32S active balancing series BMS, independently developed and manufactured by Dongguan Jinfen Electronics Co., Ltd., is engineered to provide precise, robust, and highly customizable battery management across every environment.

Four Flagship Board Layouts

Our active balancing portfolio ranges comprehensively from 3S to 32S, supporting continuous currents of 20A to 320A (finely adjustable in 20A steps) and delivering up to 1A to 2.5A of active balancing current. To maximize spatial efficiency in diverse enclosures, we offer 4 distinct form factors (using a 24S configuration as an example):

• E-Type Layout (Double-layer): Specially engineered to minimize the battery pack footprint, making it ideal for compact, non-standard dimensional enclosures.

• H-Type Layout (Slim/Elongated): The power board and control board are designed in a narrow-strip profile, perfect for long enclosures with constrained width.

• T-Type Layout (Flexible/Modular): Features a larger control board and a smaller power board, providing layout agility for wide battery configurations.

• W-Type Layout (Side-outlet): Engineered with side-wiring ports for ultra-low profile integration and optimized thermal cooling, ideal for packs with side cell-tabs.

Three Performance Tiers

1. Simplified Tier: Optimized for cost-sensitive applications requiring robust cell-level protection and precise active balancing under standard daily operation.

2. Standard Tier: Features rich, versatile communication protocols (RS485, CAN, Bluetooth) and expansion interfaces to support complex monitoring.

3. Enhanced Tier: Designed with extreme overcurrent tolerance, reinforced thermal pathways, and robust industrial IP-rated environmental sealing.
