FEATURES

CHARGER OVERVIEW

1. Automatically identifies cell count.

2. Begins charging pack upon connection and will stop charging when proper voltage is achieved.

3. User can easily adjust charging amperage based upon pack requirements.

4. Charger can be used as a voltage checker by manually setting the charge current to “0”.

The Bias 2-4 Cell AC/DC LiPo Balance Charger is an easy to use charger designed to charge 2 to 4

cell LiPo and LiFe batteries using an AC or DC input. This charger allows the user to charge up to a

maximum of 4 cells at a time. The user can charge two 7.4V 2S packs at the same time*, or one 11.1V

3S or one 14.8V 4S pack.

*When charging two 2S packs at the same time, the max charge rate will be 1.5A per battery

When using DC power the charger input voltage must be

between 10 and 18 volts to operate properly. If input

voltage is lower or higher then you will get a

“PW Err” power error.

Charging Status Indication:

“CHGING” will be shown on the left side of Menu 1.

Full Charge Indication:

“FULL” will be shown on the left side of Menu 1 and

current rate will “0”.

WARNINGS

Please read and fully understand this entire manual before beginning the charging process.

Please keep charger out of direct sunlight. Do not store or operate charger in an environment where it may

be subjected to heat, moisture, water or dust.

WHEN CHARGING TWO BATTERIES, BOTH BATTERIES MUST BE OF THE SAME CHEMISTRY,

SAME VOLTAGE AND SAME CAPACITY.

Incorrect connections may damage the battery, or destroy the charger and void all warranties.

Keep chargers out of reach of children and pets. Children under the age of 18 must only use this

product with the direct supervision of a responsible adult.

This product contains chemicals known to the State of California to cause Cancer, Birth Defects

and other Reproductive Harm.

LiPo Battery Safety Guidelines

1. This charger is speciﬁcally designed for Lithium Polymer batteries. Never use NiCD or NiMH type chargers to charge

LiPo batteries. Doing so will damage the batteries and may cause ﬁre and personal injury.

2. Always charge batteries in a fire proof container, in the open and away from flammable materials. Do not charge

batteries on or near wood, cloth, carpet, in your model, or on or near any other flammable material. Keep a chemical

fire extinguisher nearby in case of fire.

3. Never leave batteries unattended while charging. Always observe batteries when charging so that you may react

quickly to any problems that may occur.

4. LiPo cells feature a separate balancing plug that isolates each cell in a pack and charges it independently. This

ensures that all cells peak equally and discharge at the same rate during use, preventing one or more cells from

discharging past their safe low voltage cut off rating. The balancing plug can be identified by the multi wire JST XH

plug.

5. Charge each battery pack individually. Never charge battery packs in series. Charging packs in series may result in

improper charger cell recognition and an improper charging rate that may lead to overcharging, cell damage and fire.

6. Always check to make sure that your charger settings match those listed on the battery pack label. Refer to the

battery label for the proper cell count and charging amperage setting. Selecting a cell count or amperage charge rate

other than the one listed on the battery pack will damage the battery and may cause a fire.

7. Make sure the battery connections are connected in the correct polarity. Incorrect connections will damage the

battery/charger and may cause a fire.

8. Always check battery pack voltage before charging. Do not discharge LiPo batteries below 3.0 Volts per cell. The

voltage of a typical LiPo cell at rest is 3.7 Volts. If the battery pack appears swollen or damaged, DO NOT CHARGE,

DISCHARGE, OR USE IN ANY WAY. Please contact the battery manufacturer for further instructions.

LiPo Battery Safety Guidelines Cont.

9. Do not charge at over 1C current. C= battery pack mAh capacity ÷ 1000. Divide the battery mAh capacity by 1000

to determine the proper charge rate. Example: 1200mAh ÷ 1000 = 1.20 Amps Charge Rate for LiPo Battery Packs,

example:

a. 800mAh Capacity = 0.80 Amps

b. 1200mAh Capacity = 1.20 Amps

c. 2000mAh Capacity = 2.00 Amps

11. If the battery swells or “balloons” or if the battery exceeds temperature guidelines, follow these safety steps:

a. Immediately remove the battery pack from your model or charger.

b. Place the battery in a non-flammable, well ventilated area.

c. Observe the battery for 30 minutes from a safe distance.

d. After 30 minutes, if the pack appears stable, is not swollen and does not show any signs of damage,

return the battery pack to normal use with caution.

12. If a battery is deformed, swollen or appears damaged, DO NOT CHARGE, DISCHARGE or USE IN ANY WAY.

Please contact the battery manufacturer for further instructions.

WARNING: CHARGING OR DISCHARGING A DEFORMED,

SWOLLEN OR DAMAGED BATTERY WILL INCREASE THE

RISK OF FIRE AND/OR PERSONAL INJURY.

10. Battery Temperature is critical. For optimum performance in cold climates, warm the pack to 100Fº/ 37Cº before

use. Please use the following guidelines:

a. Charge Temp Range: 32 - 110Fº / 0-43Cº

b. Discharge Temp Range: 32 - 140Fº / 0-60Cº

c. Storage Temp Ra40 - 80Fº / 4-26Cº
