24 Volt System
 

I have recently begun working with a hangar mate on an RV-10 project that I will likely become partner in. It is an older build with steam gauges that we are upgrading. Need to replace battery.

The electrical system is 24 volts, and changing that seems daunting.

The current battery is a Concorde RG24-16, and a new one is about $700. I have previously had PC680s in the two RV-6s I owned, and I keep thinking about how well they have served me and that they cost about $130.

I am wondering about the feasibility of running two PC680s in series. About the same weight and footprint, a couple of extra amps, and less than half the cost.

Any reason not to do this?
Any thing to look out for if going this route??

Thanks in advance,

No issues running two in series to get 24 volts. I'd recommend changing them together as well in the future every few years.
