◎ SAFETY PRECAUTIONS
1. Do not attempt to charge incompatible types of rechargeable batteries. This charger is
designed to only charge and discharge Nickel Cadmium, Nickel Metal Hydride, Lithium
Ion, Lithium Polymer, and Lead Acid batteries.
2. Do not attempt to charge a dead or damaged battery.
3. 12V input from Pb battery or reliable 12V power supplier that can supply more than 7A
current is needed
4. Make sure to place the charger on a rm level surface for charging.
5. Do not attempt to charge batteries at excessive fast charge currents. Check with your
battery manufacturer for the maximum charge rate applicable to your battery.
6. Do not allow water, moisture or foreign objects into the charger and use in a well ven-
tilated area
7. Do not place the battery or charger on or near a ammable object while in use. Keep
away from carpets, cluttered workbenches, etc.
8. Do not leave the charger unattended while charging. Disconnect the battery and
remove input power from charger immediately if the charger becomes hot and keep
the charger and battery cool down before reconnecting. Young children should be
supervised to ensure that they use the appliance safely
9. Do not disassemble the charger.
10. If lead-acid battery is used to charge battery, the battery terminal shouldn’t be con
tacted to the chassis
11. Do not use automotive type battery chargers to power the charger.
12. Do not cover the air intake holes on the charger as this could cause the charger to
overheat.
13. Connect the input leads to a 12V power supply rst, then connect the battery.
14. Do not attempt to charge non-rechargeable batteries.

※ The charge voltage setup
When the charge or discharge of lithium battery is
started without connecting the balance board to the
balance port of the charger.
When the charge or discharge of lithium battery is
started with connecting the balance cable to the bal-
ance port of the charger.
LiPo = 3.7V~4.3V LiIon = 3.6V~4.1V LiFe = 3.2V~3.7V
For safety purposes, this charger is designed to automatically deliver 1C charge rate
to lithium batteries Example : LiPo cell of 1500mAh capacity : 1C = 1500mAh ( = 1.5A )
charge current.
The maximum voltage for LiIon is 4.1V per cell, LiPo is 4.2V per cell and LiFe is
3.7V per cell. Therefore, it is extremely important to choose the correct battery type
to be charged, as each Lithium battery has the different voltage level. Otherwise, it
may cause very serious damage to the batteries and increase the risk of a re !

If you know the battery capacity, you may estimate charge time approximately
Ex) If 7.2V 2000mAh NiCd battery is charged with 3.0V, charge time is (2.0/3.0)x60, ap-
prox 40 minutes It is just for your reference, not the correct time

◎ NEW BATTERY CHARGE
◎ Pb BATTERY SAFETY
When the new NiCd/ NiMH are charged at the rst time, charge process might be termi-
nated within minutes, it is not because charger or battery have a problem, but because
battery is not stabilized yet. In this case, you need to charge battery after increasing the
delta peak value or to charge battery after discharging and cooling down battery.
Do not use the battery, if the charged capacity of battery exceeds battery capacity in
specication. If such a phenomenon arises, repeat to charge and discharge more over 5
times and charge again. Such a phenomenon might arise till the third time charge.
Pb battery needs to be charged every day. If the charged capacity of battery is dropped
below 50%, this battery might not be recharged. The average charge time of Pb battery
is 4~5 hours. Do not charge Car battery, the charger might get the serious damage
◎ LiIon, LiPo, LiFe BATTREIES SAFETY
1. Always charge the batteries that have Lithium ion or Lithium polymer mark and do not charge
the batteries that have Lithium mark. Failure to do so will damage the batteries and may
cause re or personal injury.
2. Always charge the batteries that the cell voltage ( 3.3V / 3.6V / 3.7V ) is written
3. Ensure that the charger and battery are placed on a non-ammable surface whilst charging.
4. Never charge Lithium ion/Polymer/Fe batteries inside a vehicle whatever the circumstances.
5. Always ensure that the charger is correctly set for the battery being charged, checking both
voltage and capacity. Be particularly careful if using a series/parallel battery pack, or if using
packs of different specications with the same charger.
6. Never charge at a rate higher than that recommended by the cell manufacturer, this can be
very dangerous.
7. Do not leave Lithium ion/Polymer/Fe batteries unattended whilst they are charging. Monitor-
ing the batteries during charging is very important.
8. Always monitor the temperature of the battery being charged every few minutes. If the battery
becomes hot to the touch, disconnect it from the charger immediately and allow to cool. Do
not recommence charging until the battery and charger have been checked for compatibility
and the charger settings have been conrmed as being correct.
9. In the unlikely event of the Lithium ion/Polymer/Fe battery catching re DO NOT use water to
attempt to put the re out, instead use sand or a re extinguisher designed for electrical res.
10. When used correctly, Lithium ion/Polymer/Fe battery packs are as safe as any other type of
rechargeable battery pack. However they do require different charge regimes to the longer
established Nickel Cadmium and Nickel Metal Hydride technologies and have the potential
of catching re if severely mistreated.
11. If Lithium Polymer battery packs are short-circuited or severely over-charged elemental Lith-
ium may be deposited internally, and if the battery pouch is damaged this can escape from
inside the battery. If this occurs a re may be caused, as elemental Lithium is highly reactive
when exposed to water or moisture, producing ammable hydrogen gas and corrosive
fumes. Elemental Lithium is not produced unless the battery pack is severely mistreated, so
in normal usage there is no likelihood of explosion or re.
12. Lithium Ion/Polymer battery packs must NEVER be discharged below 3 volts per cell (LiFe
2.0V) as this will result in damage to the cells. If the voltage is allowed to drop below 3 volts
per cell the battery voltage may seem to recover following a charge, but the battery may
not then give its full nominal capacity and a reduction in performance is likely - allowing the
voltage to drop below 3 volts per cell will invalidate all warranty claims.

19
13. Never charge Lithium Polymer battery packs at greater than 4.2V per cell, Lithium Ion
at 4.1V volts per cell or LiFe at greater than 3.7V per cell as this will cause irreversible
damage to the cells and will invalidate all warranty claims.
14. Never charge Lithium battery packs above their maximum charge rate. This can dam-
age the pack and can be dangerous. Generally, Lithium Polymer packs should not be
charged above 2C (2 x Capacity). However, some newer packs do allow charging at up
to 5C, but charging at these higher rates will reduce the life of the pack.
e.g Pack of 2500mAh capacity : 2C = 5000mAh = 5A max charge current.
15. Do not use discharge rates in excess of those specied with the battery pack as this
will result in a signicant drop in voltage under load and will dramatically reduce the
number of charge/discharge cycles the battery pack will give. If disposing of Lithium
battery packs ensure that the pack is fully discharged by using a light bulb, electric
motor or similar to completely discharge the pack.
◎ ENVIRONMENT PROTECTION NOTES
16. Before charging any Lithium battery packs they should be closely inspected for any
damage, such as punctures in the sleeving or if the battery has swollen or expanded
in size. If any such damage is detected Do not charge, even if the battery otherwise
appears to be brand new.
17. Before commencing charging always double check the settings on the charger to
ensure it is set correctly for the battery pack to be charged. Using the wrong settings
is likely to result in damage to the battery pack being charged and could result in the
battery catching re.
