shall be sealed with tape when they are removed from the control unit
or from the DEI-NT.

supply 12V/20 or 24Ah. The two 12V packs (wired parallel) are
protected by fuses against discharging each other when defective and
against over current.


Recharging is via the socket 12 V in the main bulkhead. Therefore
switch on the main switch. to the first (charging) position. You don't
need to remove the batteries for charging.
Caution: Use only automatic chargers suitable for sealed liquid acid batteries.
To charge the batteries to their max. capacity such a charger with a max. output
voltage of 14.4 V is required (most chargers supply only 13.8 V). A suitable
charger Z 08 is supplied by DG Flugzeugbau.
