1. Working principle The Flycap capacitor based transfer drives the charge balancer. The balancer board is connected to the battery to start balancing, and it uses an ultra low internal resistance MOSFET and a 2 oz copper thick PCB for performance and reliability. 2. Balancing current and standby details Balancing current range: 0-5 A. The more balanced the battery cells, the smaller the current required for balancing. Reserved wiring position for the standby switch. The idle operating current in standby/off mode is less than 0.1 mA. The balancing voltage accuracy is within 5 mV. 3. Technical parameters Quiescent current (idle) is approximately 12 mA. Recommended battery capacity per balancer is 60–300 Ah. 4. Protection features Active Equalizer Balancer includes under voltage sleep protection. If a cell voltage drops below 3.0 V, the unit automatically halts and enters sleep state, with standby current less than 0.1 mA. 5. Key attributes and benefits - Function: Provides active equalization to balance large battery packs and maintain uniform cell voltages. - Compatibility: Suitable for balancing applications in packs sized 60–300 Ah per balancer. - Size and construction: 2 oz copper thickness PCB for improved conductivity and thermal performance. - Materials and electronics: Uses ultra-low internal resistance MOSFETs to minimize heating and improve efficiency. - Performance: Precise balancing with voltage accuracy within 5 mV and low standby consumption (less than 0.1 mA in sleep). - Protection: Built in under voltage sleep protection to prevent deep discharge and protect the pack. 6.
