I am gearing up a Kingcat and want to keep it simple as well. I was thinking of using two smaller 5 cell packs (1400 each?) with two regulators and two switches, with both plugged directly into the receiver. This would give me around 2800 mah, with some redundancy. Any reason why this won't work ? Opinions ? Thanks-Mike Oberst
This is a good setup IMHO. I use it on everything.
The only downside to this, is that many of the regulators on the market do not have a very high current rating, maybe 7 amps. So if you loose one of the power busses it is not clear the second one can handle the load. I still go with it, cause to do otherwise I would have to design and build a new regulator, or buy a new brand which I am not too keen on doing.
You also have to be careful to check both switches/regulators before flight, if not you could have a latent failure that you would not know about until it was too late. Make sure when you charge you see about an equal amount going into each pack. This can be hard to achieve in practice, sometimes I switch the batteries/regulators around every 20-50 flights or so to help equalize the use of the packs.
Good luck.
