EATURES
2.1 The charger's power input requires
11V to 14V DC power. Higher or reversed
voltages will cause permanent damage and
will void the warranty.
2.2 There are two LED status lights. The red light indicates that
power is connected to the charger. The green light means that
charging is in progress. The green light goes out when charging is
complete.

LECTRICAL PECIFICATIONS
3.1 Input Voltage: 11V-14VDC at l.2A. A voltage regulated 11V-l4V
DC supply may be used. Or a 12VDC automotive battery (rated at 15
AH or higher).
3.2 Output voltage:
2S operation: 8.4 VDC
3S operation: 12.6 VDC
3.3 Output Current: 800 mA typical
3.4 Output Balance Accuracy: 20mV typical
3.5 The red alligator lead is the Positive power input, and the
Black alligator is negative input. Do NOT connect the power leads
backwards (reverse voltage). This will damage the charger and void
the warranty.

HARGING ROTECTION
4.1 Microprocessor based real-time monitoring techniques use
precise calculations to ensure a full battery charge indication. It
helps to ensures safe and reliable recharge control, which extends
battery life.
4.2 The fully charged battery voltage difference, between the
individual cells, is typically less than 20mV. Charging cut-off
voltage is between 4.18V to 4.20V.
4.3 The charger automatically detects if the battery pack is two
(2S) or three (3S) series-connected cells. There is a cable port
connection dedicated for 2S packs and another one for 3S packs. Do
not charge more than one pack at a time. DO NOT install two packs!
