[RE-wrenches] Genasun

[John Blittersdorf]

Ray,
  Timing is everything.  I wish they had been around 5 years ago.  My golf
cart that has been plug in free for 5 years could have used that.  Guess I
continue with the 3 Sunwize 80 watt panels.  I was having trouble finding a
good outdoor charge controller until Midnite came out with the BRAT.  Just
hooking that up now to prevent overcharging.
