JIKONG 8S-16S 200A Household Energy Inverter BMS with 3.2/4.3/7.0 Inch LCD Display

JIKONG 8S-16S 200A Household Energy Inverter BMS with 3.2/4.3/7.0 Inch LCD Display

The JIKONG 8S-16S 200A is a smart Battery Management System with active balancing (non-lossy balancing) technology, designed for 8S–16S LiFePO4, Li-ion, and LTO battery packs in household energy storage and inverter systems. It transfers energy from higher-voltage cells to lower-voltage cells, achieving voltage balance with minimal energy loss. It operates continuously during charging, discharging, or idle states until the voltage difference is within the set range.

With a 200A continuous current rating and available in 0.6A or 2A active balancing current, this BMS is ideal for residential inverters and medium-to-large battery banks. Dedicated LCD displays are available in 3.2-inch, 4.3-inch, and 7.0-inch sizes for real-time monitoring of cell voltage, current, and temperature.

What is Active Balancing?

Active balancing transfers energy from cells with higher energy to those with lower energy, achieving voltage balance with minimal energy loss. It operates continuously regardless of charging, discharging, or idle states, until the voltage difference is within a set range. Since it involves energy transfer without heat generation, active balancing can use larger currents (commonly 1A–2A) without affecting cooling. It is more suitable for larger capacity battery packs due to longer balancing times and higher currents.
