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.
2.0 F
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.
3.0 E
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.
4.0 C
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!

Summary

Product Description and Manual Guidance

Importance of Reading Manual

Stresses the necessity of reading the manual for proper operation and safety.

Charger Key Features

Power Input Requirements

Requires 11V-14V DC. Incorrect voltage or polarity will cause damage and void the warranty.

LED Status Indicators

Red LED signifies power connection; Green LED indicates charging in progress, turning off upon completion.

Technical Electrical Specifications

Input Voltage and Current

Input voltage is 11V-14V DC at 1.2A. A regulated supply or 12VDC automotive battery is acceptable.

Output Voltage and Current

Outputs 8.4 VDC for 2S and 12.6 VDC for 3S operation. Output current is 800 mA typical.

Balance Accuracy and Polarity

Balance accuracy is 20mV typical. Proper polarity of input leads is critical to prevent damage.

Charging Protection Features

Microprocessor Monitoring

Utilizes real-time monitoring for precise calculations to ensure safe charging and extend battery life.

Cell Voltage Monitoring

Monitors cell voltage difference (<20mV) and charging cut-off voltage (4.18V-4.20V).

Automatic Pack Detection & Usage

Automatically detects 2S/3S packs via dedicated ports. Only one pack should be charged at a time.

General Safety Precautions

Unattended Charging and Location

Never leave charger unattended. Charge on concrete, 10ft from combustibles, away from flammable liquids.

Battery Compatibility and Condition

Use only with LiPo packs. Do not charge hot, swollen, or damaged batteries.

Handling and Storage

Do not disassemble. Keep away from children/animals. Do not connect more than one battery pack.

LiPo Battery Safety Information

Ignition Risk and Handling

LiPo batteries can ignite if not used correctly. Follow all safety recommendations.

Charging Environment and Overheating

Do not charge near combustibles, in cars, or allow cells to overheat (>140°F/60°C).

Discharge and Physical Integrity

Do not forcefully discharge. Never exceed current ratings. Do not expose to water. Inspect for damage.

Chemical Exposure and Modification

Avoid electrolyte contact with skin/eyes. Do not alter connectors or wires.
