I responded directly to Tom Hall, but there seems to be enough interest

in this to make one comment to all: Don't skimp on battery capacity or

put them in a difficult location. Starting a turbine is not like

starting a piston. You've got to have full voltage and capacity or you

risk serious damage inside the engine. You need to be able to manage the

batteries much more than with a piston, and, I suspect, replace them

more often. If you leave the plane out on a ramp somewhere for the

weekend and the batteries are weak, you may be stuck. You may also be

tempted to push a weak battery start, which is risky. You should

consider a convenient plug for a Battery Minder and/or a solar panel.

Definitely provide a handy cart connection in the nose well (or

somewhere).

The subject of turbine

The subject of turbine batteries is still a valid one. I am tagging onto this 20 yr old post  as its most appropriate.

Lithium batteries are now available for those interested and for those that still prefer lead, a portable GPU carry-on is wise to have. Why stress the main ship battery starting ?

What are the turbine drivers doing for batteries  ???

I'd like to awaken this thread if possible.

I switched from Concord to two Earth-X ETX-1000 batteries wired in parallel.  This is the config that Earth-X recommended.  During start sequence, the turbine spins up much faster.  My batteries are on the fwd firewall, so the 28# weight reduction required me to add a 20# lead brick to keep CG from moving too far aft.
