I recently ordered a Tekin Battery Nurse to try and help me with my 4 cell spec batteries. Any info on this would be greatful, or did I waste my money on this?

Unless You Have 10 Batteries And Only Race Once A Month You Dont Really Need It

if they are the trinity packs, they do not need the nurse, they need dead shorted.

I don't think you wasted your money. The nurse in very short words

Keeps the Good Cells from going bad should they left sitting longer than a week without a cycle or re-peak.
