Yes, you can use the batteries in parallel. This works fine providing the
batteries are of similar types, as flight packs are. However, putting SCRCs in
parallel with SCs wouldn't be a good idea, but probably wouldn't show any
adverse effects other than the lower resistance cells draining first and wearing
out first due to cadmium migration.
While you are at it, why not install a second switch also. Switches often go
bad and the extra weight isn't much. Besides, you won't need to buy the Y
harness and you will then have two charge cables. Also, don't leave the
batteries in parallel when the heli is not powered on as you would have to do
with only one switch and a Y harness, they will self discharge faster than
In case it isn't obvious, you must test the packs separately with your ESV.
Flames are always welcome, but be warned that I have extensive knowledge of
Ni-Cd technology. Also, I'd be happy to answer any questions while I'm here on
the newsgroup. I'll be sure to keep subscribed here for at least a few weeks.
