[RE-wrenches] Firefly Batteries

[Ray Walters]

1000 cycles at 80% DOD for a small format sealed battery is impressive.  
It all gets down to what they cost, and if they really live up to those 
numbers in the real world.  It also looks like they only have a group 31 
sized 12 volt model, so that limits their use to smaller GTB 
installations mostly.  Some 6 v golf cart and L16 offerings would 
definitely expand their usability. Meanwhile Full River seems to be 
holding up well in the sealed battery market, with a much better than 
avg cycle life of around 700 cycles to 80% DOD.
