I like the battery strap mod and red dot on the battery. I hooked one up in reverse just this past Monday. Sparks and heat, but lucky for me no smoke. That got my attention. Going to do that to my batteries soon. The Venums I have are easy enough to tell apart but the new ones I have are like yours, and to top it off they are reverse of my Venums I'm so used to using! A disaster waiting to happen. Thanks for the red-dot idea!
