from their website, but here is a copy if anyone needs it.

Rod Hower submitted: For those working on multiple I/O interface
with optical isolation, check out QT opto (www.qtopto.com) H11ADB. I don't
know if it is on their website, but this part was
originally developed for an application here at Ametek. We used it on an isolated analog speed control input that was compensated for temperature etc. Anyhow, this would work well for xmit & rcv and is the most space conscious part I've seen.
Tom Martin created a simple boosted bad boy charger for his 144 volt EV.
With grateful appreciation to all those who helped me with this. I would like to share with everyone my version of the Bad Boy charger. I know there are those who feel this is not effective, or not safe or not practical, or not something. Well I am here to tell ya that after a lot of errors, far to many shocks with bad language attached and even more popped circuit breakers I got to the pay-off. I found a way to make it work as the stories have said it would. There is in my picture a light dimmer which I cannot attest to because I put mine in a different and wrong place "twice". Yep, fried both of 'em. The first one popped; and the second melted. The phase of the AC is important to the final output. If the AC voltage is lower than the input then reverse the leads on the output side of the transformer. The thing won't pop even if the phase is wrong, the voltage will just be reduced by the value of the transformer. Trust me! I fought with this thing for four days. I got bit so many times, anyway this does work. This setup seems to work rather quickly, I put it on my 144v pack and the voltage went from 150 to 177 in about an hour. I put an amp meter in the line and it showed never more than a 15 amp draw. I tried using a long extension cord and it did reduce the current and the rate of charge. I can tell everyone that if you build one, a very important thing to do the first time is to use wire that is capable of dealing with the loads, I started with extension cord wire, "Don't do that" it gets really hot. I know! A store bought battery charger costs over 900 bucks, I don't know about the rest of ya but I had to have a more affordable method. This works and seems to work well. I will run my pack down over the next three or four days and then I will see just what the reality is.

1. This is an extract from an excellent but out of print book, "EV Engineering Guidebook: Electric Vehicle Conversions for the 1980's", by Paul R. Shipps, complete instructions on how to calculate the weight and balance of a potential EV conversion.
2. David Brandt has created an excellent balance worksheet in Excel.

Here is a great page with lots of info on the GM 12 volt vacuum pumps and how to install them. The page was written for RVs but it applies to EVs as well. (thanks to Andrew Letton for pointing it out.)
