I've had good success on my ski boat with an Interstate battery charger. Typical auto on/off with some sort of pulse algorithm (I think this one has it). Anyway, it's compact and would likely fit in with the battery, then just run a cord out of an easy access location.

'06 M5, took ED on Aug. 28th, 2006 in Munich!

VANOS killed M5 engine - totaled out 9/9/2011.
M5 currently in purgatory awaiting its fate...
1. either let go to insurance company and auctioned off for parts, OR...
2. purchased back and reborn with a Dinan stroker engine!
Option 2 please, DONE!
