Not to start the battery wars again but has anyone installed 2 PC680 batteries and put one up front somewhere, ie. Firewall. If so, where does it fit and how is it on W&B. I know Tim has smaller batteries under his seat I believe.

I put 2 PC680 batteries just behind the baggage compartment bulkhead. Used 2 of Van't battery mounting boxes. Not much of a flicker on the W&B for me.

I have two 680's but they are both in the back. Due to the weight factor I suggest you keep as much controlable weight aft of the CG. Although I have not finished mine yet, all information to date indicates a the -10 flies better with more weight aft of the CG. With the CG at the forward limit the aircraft requires more aft stick to develop a nice flare. Little flight experience but lots of reading about it. YMMV.

I have a pair of PC-680s but they are in the standard battery location (minor mod to the battery tray).

Rick,
We haven’t done it yet but we are planning 2 PC680s, one up the front to crank the engine, and the second down the back for the endurance bus. We plan to follow Bob Knuckolls’ approach of changing out the cranking battery and rotating the new battery down the back to maximize life on the endurance bus battery. We have purchased the RV7 firewall mount kit and we will locate it when we have the engine hung. I would prefer to hang it on the engine side of the firewall, but if I can’t, then we will put it inside somewhere ’convenient’.
I have done several W & B calcs using the numbers other people have published for their RV 10s and I feel comfortable with the results. Being a first time builder we have gone a bit overboard with the primer on the empennage parts, which is all weight way down the back and we are looking at the light weight starter and alternators which reduces weight at the front.

Bob,
Any chance of getting a pic of your battery tray mod?

Don;'t know about how Bob did it, but I've got 2 PC 680's, and here's a
link to 11 pics that should give you and idea how I went about it.

Attached is my approach and I sent a series of pictures offline so as
not to clutter up the list (I think they've been posted before).
Essentially I took the easy way out and just widened the stock tray on
the non-contactor side and moved the aft angle forward a bit. I have
both contactors mounted on a piece of angle that's bolted into the stock
contactor location.
