Key benefits Precise cell balancing: balance current range 0–5.5 A lets the board actively equalize cell voltages; the more balanced the battery pack, the lower the balancing current required. Low standby power: current mode (quiescent/standby) is under 0.1 mA, minimizing drain when the board is idle. Stable voltage compensation: compensation voltage accuracy within 5 mV ensures tight matching between cells. Durable, low-loss power stage: MOS circuit board uses 2 oz copper thickness for extremely low internal resistance and improved thermal/current handling. Core functions and how it solves problems Capacitor works with the transfer-charge slider to manage transient charge flow during balancing and discharge events, reducing spikes and improving stability. Connect the balance board directly to the battery and start the scale; the board performs balancing automatically within the specified current range, keeping cell voltages matched and extending pack life. Manual sleep switch allows the user to place the board into a low-power state when balancing is not needed, preserving battery capacity. Key specifications and attributes Balance current: 0–5.5 A Standby/quiescent current: < 0.1 mA Compensation voltage accuracy: within 5 mV Power stage: MOS circuit board with 2 oz copper thickness and very low internal resistance Controls: transfer-charge slider and manual sleep switch Connections: balance board connects to the battery for operation and scale start Practical applications / use scenarios Battery assembly and testing: use during pack formation and testing to equalize cells and verify pack balance before installation. Field maintenance: place the board on a battery pack in service to rebalance under load or before charging, then switch to sleep to eliminate parasitic drain. R&D and prototyping: integrate with battery test setups where accurate, low-drift compensation and reliable current handling are required. What to expect in use Reduced cell imbalance and longer usable pack life when balancing is applied regularly. Minimal added drain when the board is idle thanks to the very low quiescent current and manual sleep option. Robust current handling and lower thermal rise due to the 2 oz copper MOS board design.
