b) Connection of a Rechargeable Battery to the Charger

Please observe the following points before connecting or charging/recharging the battery:

• If you have not done so already, please read chapters 5, 6 and 7 completely and ensure that you have

understood the information there.

• Do you know all of the information you need to know about your battery? Unknown or unlabelled batter-

ies, the necessary values of which you do not know, must not be connected/charged/discharged!

• Have you selected the correct charging/discharging program for the type of battery you are using? Incor-

rectsettingswilldamagethechargerandthebattery;thereisadangerofreandexplosion!

• Did you set the correct charging or discharging current?

• Have you selected the correct voltage (e.g. for multiple-cell LiPo batteries)? A two-cell LiPo battery may

be switched in parallel (3.7 V) or series (7.4 V).

• Areallconnectorcablesandplugsundamaged,dotheplugsstayrmlyinthesockets?Wornplugsand

damaged cables should be replaced.

• Connect only one single rechargeable battery or rechargeable battery pack to each of the two charging/

discharging channels of the charger, but never several at once per charging channel. Never connect the

two channels to each other! Each of the two channels is independent of the other.

• When connecting a rechargeable battery to the charger, always connect the charging cable to the charg-

errst.Onlythenmustthechargingcablebeconnectedtotherechargeablebattery.Whendisconnect-

ing,proceedinreverseorder(rstdisconnecttherechargeablebatteryfromthechargingcable,thenthe

charging cable from the charger).

chargeable batteries!

• If you wish to charge battery packs that you have manufactured yourself, the cells must be identical in

their construction (same type, same capacity, same manufacturer).

The cells must also be charged to the same level (lithium batteries can be balanced out using the bal-

ancer. This is, however, not possible with other battery packs such as NiMH or NiCd).

• Before connecting a rechargeable battery/battery pack to the charger, disconnect it completely, e.g. from

aightorspeedcontroller.

Important when charging/discharging a lithium battery pack with balancer connection:

Multi-cell lithium battery packs usually always have a balancer connection. This permits the charger to monitor the

voltage of every single cell separately at all times.

The charger adjusts the voltage of all cells to each other if there are deviations. The balancer prevents that one or

severalcellsareover-chargedorothercellsnotsufcientlyfullychargedbythis.Thebalancerthereforeprotectsboth

fromover-charging(whichmaycausereorexplosion)andfromdeepdischargeofasinglecell,andthusensures

best performance of the battery pack in your model.
