I guess if we take it out of the plane it still has to go somewhere. Anyone hookup a Solar Charger or Inverter System that will charge the bigger batteries.
Harbor freight also has some small cheap gensets if you don't want to build your own. I've seen these ready to go on sale for $100.
Yeah, I've gone the route of two 120 Ampere Hour deep cycle batteries in parallel for charging them 24 A123 cells in my Big Stick. Problem is the Cellpro Powerlab 8 charger is pulling 54 Amps out of the 12 Volt battery setup. That's way beyond what those deep cycle batteries are rated for, and I've found that it really kills those lead acid batteries. I got less than a year service out of two in parallel before they were crap.
As for the gensets, you can't use their 12 volt DC output, its not pure DC. So that requires a 120 VAC to 12 VDC power supply that for me, puts out 60 Amps. One of those will cost over $300, plus the $100 for the genset.
A real concern is these gensets often use an inverter inside them to provide the 120 VAC. Don't know if those inverters can handle the very high peak currents pulled by these AC/DC power supplies during their normal operation.
