50Ah Operation

(1) Keeping POWER off, VOLTAGE REGULATOR off, CHARGE REGULATOR at 0, then connect the red clip to battery red pole(+), connect the black clip to the battery black pole (-). DONOT reverse.

(2) Choosing battery charging voltage: if charging with only one battery of 12 V, turn the VOLTAGE REGULATOR to 12v (It has two gears, choose any one is ok). If charging with two batteries in series, the charging voltage should be 24V. If charging with three batteries in series, the charging voltage should be 36V, and four batteries in series should be 48V.

(3) Plug the charger head to light, then turn on the POWER to charge.

(4) If the battery is empty, or at night charging, the CHARGE REGULATOR should put for gear below ⑤. If the battery is charged up with 50% or more, then you can turn to higher gear up to ⑨⑩.

(5) When fully charged, the AMP meter will point to 0 (or near 0, which is on floating charge)

(6) Charging current control: it would be the best that start charging an empty battery according to its capacity at one tenth ratio (eg, a 120Ah empty battery, start charging current with 12A)
