SAFEty prEcAutions  
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, LiFePO4 and Lead-  
Acid batteries.  
• Make sure you place the charger on a firm level surface for charging.  
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.  
DO NOT use automotive type battery chargers to power the charger.  
DO NOT leave the charger unattended while charging. Disconnect  
the battery and remove input power from charger immediately if the  
charger becomes hot. Allow the charger or battery to cool down before  
reconnecting.  
DO NOT allow water, moisture or foreign objects into the charger.  
DO NOT place the battery or charger on or near a flammable object  
while in use. Keep away from carpets, cluttered workbenches, etc.  
DO NOT cover the air intake holes on the charger as this could cause  
the charger to overheat.  
• Connect the input leads to the 12V power source first, then connect the  
battery.  
DO NOT disassemble the charger.  
• This unit is not intended for use by young children or infirm persons  
unless they have been adequately supervised by a responsible person to  
ensure that they can use it safely.  
• Young children should be supervised to ensure that they do not play  
with the Typhoon L50B Pro.

Lithium Ion/polymEr BAttEry  
SAFEty WArnings  
Ensure that the charger and battery are placed on a non-flammable  
surface whilst charging and ideally charge outdoors wherever possible.  
NEVER charge a Lithium ION/Polymer/Fe battery inside a vehicle whatever  
the circumstances.  
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 specifications  
with the same charger.  
NEVER charge at a rate higher than that recommended by the cell  
manufacturer, this can be very dangerous.  
DO NOT leave Lithium ION/Polymer/Fe batteries unattended whilst they  
are charging. Monitoring the batteries during charging is very important.  
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 confirmed as being correct.  
In the unlikely event of the Lithium ION/Polymer/Fe battery catching fire  
DO NOT use water to attempt to put the fire out, instead use sand or a  
fire extinguisher designed for electrical fires.  
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  
fire if severely mistreated.  
If Lithium Polymer battery packs are short-circuited or severely  
over-charged elemental Lithium may be deposited internally, and if the  
battery pouch is damaged this can escape from inside the battery. If this  
occurs a fire may be caused, as elemental Lithium is highly reactive  
when exposed to water or moisture, producing flammable 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 fire.

Lithium Ion/polymEr/FE BAttEriEs  
Lithium battery packs must NEVER be discharged below 3 volts per cell  
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.  
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.  
DO NOT use discharge rates in excess of those specified with the battery  
pack as this will result in a significant drop in voltage under load and will  
dramatically reduce the number of charge/discharge cycles the battery  
pack will give.  
DO NOT attempt to charge Lithium battery packs whilst the input  
12 volt battery is being charged, as the voltage supplied to the Lithium  
Polymer charger may be too high.  
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.  
DO NOT allow any Lithium battery pack to short-circuit as this is likely to  
result in a minor explosion and consequent fire.  
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.  
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 fire.

Input powEr  
12V DC  
Connect the charger’s red alligator clip to the positive (+) terminal on the  
power source and the black alligator clip to the negative (-) terminal. The  
charger will display “Input voltage” error message if the input is below 11V  
or above 15V. If this happens, please recheck the input power supply to  
make sure correct power is present.  
Output BAttEry ConnEctions  
Two 4mm banana sockets are located on the right side of the charger.  
Connect the battery main power leads to these sockets with the positive  
(+) lead connected to the red socket and the negative (-) lead to the  
black socket. You may need to purchase an adaptor lead to suit the  
specific connector on you battery and make this more convenient. The “No  
battery” error message will be displayed if trying to start charging without  
connecting a battery to these sockets. The “Open Circuit” error message  
will be displayed if a battery becomes disconnected from the charger  
while a function is in progress. A “Reverse Polarity” error message will be  
displayed if a battery is connected to the charger in reverse.  
Note: In order to balance Lithium batteries during charge, please ensure  
that both the battery main power leads and the balancing connector from  
the battery pack are connected to both 4mm output banana sockets and  
balancing port respectively. The balancing port (JST EH type) requires a  
short lead (supplied) and an adaptor board to suit other battery balance  
connectors. Two types are supplied to suit Polyquest, Flight Power and  
Thunder Power batteries (TP). Other types are available as options.  
If the main battery power leads ONLY are connected to the output banana  
sockets, without connecting the balancing connector to the balancing port  
on the charger, the charger will charge or discharge the connected Lithium  
pack without balancing it.

LI + 3.00A 12.000V  
This charger is capable of charging up to 6 cell Lithium-Ion, Lithium-Polymer or  
LiFePO4 batteries. It uses “constant current / constant voltage” regime in order to  
fully charge these Lithium batteries. Constant current is delivered during the fast  
charge. When the voltage of the Li-Ion, Li-Po battery and LiFePO4 reaches approx  
4.1V, 4.2V, and 3.7V per cell respectively, the charger starts to change its charge  
method from “constant current” to “constant voltage. The “constant voltage” allows  
the battery to dictate how much current the charger should deliver for safe, full  
charges. When the current drops below approx 1/10th current of the user selected  
battery capacity, the charger will stop charging as the battery is fully charged.  
Setting Battery Capacity

C=3000mAh 10.8Vp  
Always set the capacity first. When the capacity has been set, the  
current will automatically show an equivalent of 1C. For instance,  
a 3000mAh battery will initially show 3A. This can be varied up to  
2C (6A max) or down to 0.1A using the INC & DEC buttons. That  
current may be further limited automatically to a lower value if  
the charging power exceeds 50W (Amps x Volts).  
IMPORTANT NOTE  
For safety purposes, this charger is designed to automatically deliver a 1C charge  
rate to batteries of Li-Ion, Li-Po or Li-Fe, based on the user selected battery capacity  
unless over-ridden only for batteries designed to accept 2C charging.  
Example: Li-Po cell of 1500mAh capacity : 1C = 1500mAh ( = 1.5A ) charge current.  
Setting Battery Type  
Lithium Type  
Choose the desired battery type (Li-Ion, Li-Po or Li-Fe ) with  
the INC & DEC buttons. Press the ENTER button to confirm the  
setting.  
IMPORTANT NOTE  
The maximum voltage for Li-Ion is 4.1V per cell, 4.2V per cell for Li-Po batteries  
and 3.7V per cell for Li-Fe batteries. Therefore, it is extremely important to choose  
the correct Lithium battery type to be charged, as each Lithium battery has a  
different voltage level. If not, it may cause very serious damage to the batteries and  
increase the risk of a fire!
