GENERAL OPERATION

OUTPUT BATTERY CONNECTIONS

The Emperor L702B Pro has two sets of outputs on the front of the charger, channel 1 is on the left and channel 2 on the right. Each channel has two 4mm banana sockets, a 7 cell balance port and a temperature sensor input.

You will need an appropriate charge lead to suit the specific connector on your battery. Connect this charge lead to the 4mm output sockets on the charger channel you want to use, with the positive (+) lead connected to the red socket and the negative (-) lead to the black socket.

Only connect the battery to the charge lead AFTER the charge lead has been connected to the charger, as the connectors on the charge lead could touch together and cause the battery to short circuit.

When charging a Lithium pack, make sure that the balance lead is connected to the charger. The charger has a ‘JST-EH’ type balance port, but also comes with balance adaptor boards for JST-XH and Flight Power/Thunder Power. To use an adaptor board, connect the supplied balance adaptor board lead to the charger and then connect the board that works with your battery balance connector. Optional adaptor boards for Polyquest & 4/2mm plug car packs are also available.

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.

We always recommend balancing a Lithium pack, because some cells may retain more capacity than others, so over time the pack can become unbalanced. If an unbalanced pack is then used, some of the cells will exceed their maximum voltage when charged and others their minimum voltage when discharged, which causes damage to the cells. When a Lithium cell is overcharged, it can cause damage and in extreme cases can cause a fire.
