Ignition Battery Voltage

       Remove this ad - become a site supporter!
I'm just in the process of making up my battery packs for my new planes.

I am using Sanyo AA 2700mAh 6.0v packs for the Rx & Servos. I have a 50cc gas engine with EI and am wondering what voltage to use.

I was told by the Mfg. that I can either use 4.8v or 6.0v packs but if I use 6.0v, he recommends that I use a regulator. Is there any real advantage going 6.0v and having to use a regulator over just using a stand alone 4.8v pack??

I was thinking that there must be some advantage going 6.0v as the packs cost more plus the cost of the regulator, but I just don't know what that advantage might be. Would appreciate your help!

Thanks in advance for your input.

Keep the ignition for DL50 to 4 cells i.e 4.8 volts. No need for 5 cell pack. I used last season an 800mah 4 cell pack for the Dl50 and it was plenty enough for 4 to 5 flights

There is no advantage to going to 6 volt pack if you need a regulator to drop it down. The drop in voltage ends up in heat which is wasting power. I use a nimh pack (AA cells) 2200ma which is enough for me for the day. If it is not enough you can always put it on charge for a bit.
