I did not get any responses to my previous post (repeated here) so if you did put in the diodes i would appreciate a picture.

"Does anyone have a picture showing (or could take one and post) a good way to safely incorporate the diodes (Spets 8/6/12 post of circuit) mechanically into the circuit? I have not seen many (any?) pictures of the battery harness side which is were I assume the diodes should be mounted. I'm thinking of embarking on building one of these chargers but would like to see examples of the entire setup first.

Thanks. Looking at Peter's picture seems to show a diode on both the positive and negative leads to the battery connections. Guess I will do that. I ordered two of the GINO 30-90 V 300ma power supplies today. Hopefully I will get them! Have not decided on the 12V supply for the battery fan. May wait and see if I can get the charger up and working first and then add the fan.

Default 12V Fan Supply

I recently bought a few of these to try as the 12V supply in my grid chargers.

They are 12V output constant voltage.

Very cheap.

I was thinking about trying to find something like this, only in a higher amperage, to splice to my fan to cool the battery while charging. I bought enough power sources to provide up to 1A. Would this provide enough cooling? I thought I could fast charge it this way up to a certain point with the fan on, then trickle charge it the rest of the way. It's not very high on my priority list, as I need to install my MIMA and I am still waiting on my OBDII C&C.

The little 12v supply I linked too should run the fan fine.

Oh, ok. Maybe I missed a decimal point. When I was in the battery compartment to install the charger, I thought it said 5 amps. I take it it was more like .5 amps.

Annnnnd, I got my first IMA light. I am not sure whether it came from a more aggressive use of assist, or from the bcm thinking there was less in the battery so it dialed up a forced charge. The IMA came right after a force charge.
