Default No BS

Here's a question for you guys who are running 2 receivers out there. I was looking at getting some new NiMH batteries from No BS Batteries and saw that it is possible to get batteries with 2 connectors. The question I have is, if I get a battery with dual connectors could I plug that battery into both receivers without any problems? I'm pretty sure this wouldn't be an issue but I figured I would check to see if anybody else is doing this. The final configuration would be as follows: I would have 2 receivers, 2 switches, and 2 batteries. I intend to plug each battery into both receivers therefore providing redundant power in case of failure.

I was considering a setup like you mentioned... and a team Futaba flyer and good friend sent this to me....

DO NOT cross the regulators from one side to another. A common failure is indeed the regulator and switches which will be somewhat resolved the way you have it drawn up. However, in the event of a short which also happens, you would then loose both rx's and overload the second regulator


SO I will run one battery into one RX and the other battery into the other RX

That is good information, as I was still considering lithiums as well. But my initial question was based on using NiMH batteries.

from the way I was looking at it... the battery chemistry doesn't matter...

if one Ni pack does... it would take the other with it, unless they are isolated somehow.....

Whether it be NiMh or Lion, I agree with this 100%. You want 100% electrical isolation between receivers. Crossing the batt's ruins the isolation. I would keep them totally separate for true redundancy. That way a failure in one receiver/switch/reg/batt has absolutely no effect on the other receiver/switch/reg/batt.

The only thing the dual leads on that battery are good for is to put two switches on one battery, assuming your failure will be a switch. Problem with that is if the batt goes, and it's the only batt, it's all over.
