LiPo with Balancer
EH
The battery charger is equipped with a large number of protective and monitoring systems designed to check the machine's individual functions and
electronics. If any limit value is exceeded, or if the charger is operated incorrectly, it generates the error messages described in Chapter 19; it may also
terminate the charge process (e.g. if the car battery is almost fl at). Nevertheless you should always avoid connecting the batteries as shown in the illustra-
tions below, since - for example - under certain circumstances a defective battery may not trigger a warning, and this may result in damage to the charger.
The balancer sockets are polarised; watch out for the lateral lugs. Never use force to insert a connector; plugs should slide smoothly into sockets.
Most cables are colour-coded: black (brown) wire = negative (-) terminal; red wire = positive (+) terminal.

WARNING: never connect your batteries as shown in the pictures above, as this may damage the battery or charger. Fire or explosion hazard!
