I'm away from the office but will re-post the links to these to documents when I get back. It may well be that there's a bright future for lithium technology in airplanes. Here's a supplier of off the shelf devices that has developed quite a following in the recreational vehicle and motorcycle markets. http://www.shoraipower.com/ Their batteries are fitted with special connectors that service a specialized charger/cell-balancing accessory. While not 'required' . . . it's very existence suggests that these batteries are not drop-in replacements for lead-acid. http://www.shoraipower.com/downloads/shoraiLfxInstallGuide.pdf But as we all know and personally feel, the worst thing you can experience in flight is smoke/fire. Cessna thought they had cracked that nut. Both Cessna and the FAA were ready to allow these batteries aboard John Q Public's airplane. Obviously, there are some issues yet to be resolved so that probability for a repeat incident in flight drops to that magic one-event-per-billion flight hours that the FAA is so fond of. The "oncoming train" remark was inappropriate . . . energy exploitation has evolved from basking in the sun to burning wood, burning pig fat/whale oil and upward to splitting atoms. Each step offered more concentrated and energetic releases of heat. Each step also came with elevated risks. No doubt risk mitigation for the lithium technologies will eventually prove adequate.

Here is a an example of what I need, it does not need to be exactly the same equipment: http://tkmradios.com/Prod-NC_2210_Ramp_Tester.html If not too expensive, I might consider buying an used tester, even if itll sit in the hangar most of the time. AC Spruce has the new product (~$1400), but such investment does not justify the very limited and infrequent need.
