Default RE: Backup/Redundant batteries


ORIGINAL: J-P

I just downloaded the manual here

http://shop.rc-electronic.com/e-vend...=6&c=541&p=541

but did not found the explanations you are mentioning on the french or english version.

The idea to use a DPSI Micro DualBat 5.9V/7.2V or a POWERBOX™ ELECTRONIC SWITCH with one 450 Mah RX batt and 2 cells from the 10S packs looks great.

Due to the bad weather, I can't do some inflight test, so hope somebody will give it a try pretty soon

2 more quotes from the English version;

''Decoupling of both batteries in the DPSI Micro - DualBat and the
electronically switches are completely separated (inclusively peripheral
electronics) and therefore duplicated. No twin diodes (i.e. two diodes in
one housing) are being used. Malfunction of one part does not lead to
a total loss of the system. This circuitry has proven in many thousand
systems already.''

3. Low Voltage Battery 2: ⎯ ⎯ ⎯ ⎯⎯⎯⎯⎯ ⎯⎯⎯⎯⎯
DualBat ONLY error signal: LED blinks 3 x 0.05s on with 0.05s
breaks each, then 2 x 0.8s on with 0.4s break
If the voltage of battery 2 drops below a certain value, this blinking
code is output. The capacity of the battery usually suffices for one
more flight before recharging is necessary. This error code is also
repeated in a sequence of 6 seconds. If the error is qualified once, it
stays active until turning the DPSI off.
If both batteries of the DPSI Micro - DualBat indicate low voltage, both
error codes are output alternatively.

Take time to read the manual - it is a translation - could be worse, could be French to English !
