PowerBox Systems PowerPak 2.5X2 ECO Bedienungsanleitung Seite 6

CAUTION: It is absolutely essential to set the correct final charge vol-
tage (cut-off voltage)! If you charge these batteries with the cut-off vol-
tage set too high, the result could be a fire!
PowerPak x2 batteries are charged at a nominal voltage of 7.4 V, correspon-
ding to a final charge voltage of 8.4 V.
The optimum charge rate for the ECO version is 0.5C. If you are using a Power-
Pak 2.5 this means a charge current of 1.25 A. This rate of charge guarantees
a long useful life for the battery. However, it is permissible to charge at 1C (2.5
A) in exceptional cases.
Connect the PowerPak to your battery charger using the charge lead (Order
No. 2505) which is available separately. Check that polarity is correct at the
charger. The Uni connector on the PowerPak can be plugged in either way
round, as the positive (+) terminal is always in the centre.
CAUTION: Important information regarding PowerBox battery backers
and other dual power supplies:
1) All dual power supply units currently available commercially control the
charge current on the negative side.
2) All dual power supply units currently available commercially feature a
permanent connection between the negative terminals of the two bat-
teries.
These two facts make it impossible to charge two batteries simultaneous-
ly while they are plugged into a dual power supply unit! The following op-
tions are available:
a) Disconnect one of the two batteries from the dual power supply unit
for charging
b) Charge the batteries in turn, i.e. one after the other
If you ignore the points stated above, the short-circuit situation may da-
mage the battery charger! These points do not apply to the PRO version if
the integral charge circuit is used.
