Good find. I think my shopping list just grew a little.

I have been looking into one of these units why doesn't someone set up a discount or a group buy? I was thinking of contacting them but I can't seem to find the time.

Group Buy
Me too! Me too!
I've been thinking about using one of these for my twin 12"ers.
KenIf there is a hard way to do something, I'll find it!

THANK YOU, TONY!! This is a great find, and one that the majority of us could put to good use. Thanks again for sharing. Also I would be in for a GP if one is started. George

Cool!
Tony this is a great find! I wonder if they are using a power FET to regulate the voltage/current to the Fan. If they are, there should be a big heat sink attached to it somethere. It is a good idea to regulate power to the fan. It will reduce the shock to the charging system as well as maintain a more even engine temp.
Jabin- actually provding less resistance (large gauge wire) to the motor, increases the current spike. Less resistance = beter flow of electrons = bigger spike. The 50A fuse will help if the motor sustains long periods of high current draw, however short current bursts will not be caught by the fuse.
Fuse ratings are typically 110%(of rated current) forever, 135% for 30min, 200% for 5 seconds and 350% for half a second. This means that if the current spike is less than half a second long (which it should be) a 50A fuse can carry 175A and not blow.
The weak link in the system is going to be the relay. If the contacts are not all the way settled by the time the spike exceeds the rating of the relay, there will be excessive contact wear and possible sticking of the contacts. Luckily with this large of a motor the current rise time should be long enough for the relay contacts to have finished bouncing, so you should be ok.
Anyway, I will not bore you guys anymore. A group buy would be something I would be interested in.
