Key benefits Accurate cell balancing: Balances cells with a compensation voltage accuracy within 5 mV, keeping pack voltages closely matched for safer charging and more consistent performance. Low standby drain: Current mode is under 0.1 mA, minimizing quiescent power draw when idle. A manual sleep switch further reduces quiescent current when balancing is not required. High-performance MOS circuit board: Uses a new MOS circuit board with 2 oz copper thickness and very low internal resistance, improving heat dissipation and allowing reliable high-current balancing. Wide balancing range: Balance current from 0 to 5.5 A adapts to different imbalance levels—the more balanced the battery, the lower the balancing current required. How it works The capacitor operates with the charge-transfer slider to stabilize charge flow during balancing. Connect the balance board to the battery and start the scale to begin balancing and measurement processes. Manual sleep switch lets you disable active balancing to save power; the design maintains minimal quiescent current when inactive. Key attributes Function: Passive active balancing and charge transfer stabilization using a capacitor and MOS-based circuit. Compatibility: Connects directly to the battery and a scale as part of a balancing and measurement workflow. Material and construction: MOS circuit board with 2 oz copper thickness and low internal resistance for improved thermal and electrical performance. Performance: Balancing current 0–5.5 A; compensation voltage accuracy within 5 mV; standby current (current mode) less than 0.1 mA; manual sleep control to reduce quiescent draw. Practical use scenarios Battery testing and capacity measurement: Connect the balance board to a battery and a scale during lab testing to keep cell voltages matched while you measure capacity and weight. RC and hobby battery maintenance: Use during charging and storage preparation to equalize multi-cell packs, improving runtime and reducing stress on individual cells. Production or repair bench: Integrate into assembly or repair workflows where controlled balancing and low standby drain are needed before final testing on a scale. What to expect Improved cell-to-cell voltage consistency and reduced imbalance-related stress. Low idle consumption with the option to sleep the balance circuitry when not in use. Robust MOS-based handling of higher balancing currents thanks to 2 oz copper traces and low internal resistance.
