[RE-wrenches] Lithium Ion tool batteries

[frenergy]

We've sacrificed a small-medium ice chest to be the battery box for our 
tool batteries.  affixed to the side  of the ice chest is a small 7 
watt  reptile heat pad with the cord sneaking out the lid and plugged in 
overnight.  You don't want the pad on the bottom it'll actually get the 
battery setting on it too warm.

             At the job as we need them, them come out warm and by the 
time they are discharged the temp has come up to above freezing for 
charging, or put it back in the ice chest.  If its not plugged-in in the 
truck, don't forget to load the battery ice chest before the morning 
launch to work.
