The Battery box usage 4 cells (2S2P) Li-ion output 8.2V/5.2A (peak current limited in 5A).
No fuse and auto Over current ,Low Voltage,Over Temperture protection.
The EQ Linearizer remote power circuit clamp chock to reduce EMI influence.
L Channel and R Channel power path add diode to separate cross influence.
The battery module could stand alone into charge mode . So no AC noise.
The battery cells will separate to open and charging by single cell charger therefor no unbalance issue.
