Turnigy 2S/3S Lithium Polymer Battery Charger

User Manual

1. DESCRIPTION

1.1 Before using the Turnigy 2S/3S

Lithium Polymer (LiPO, Li-Po) battery

charger you must read this manual. It is

important to understand its operation and

all safety steps before

using it.

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 SPECIFICATIONS

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 PROTECTION

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!

Lithium Polymer (LiPo) BATTERY SAFETY INFORMATION If not charged or used correctly, Lithium Polymer batteries may ignite without warning and cause serious injury and property damage. If you are unable to follow the safety recommendations then do not use them. Do not leave a LiPo battery unattended during charging or discharging. Always store LiPo batteries in a secure location away from children and animals.
