Well, my luck with Optima batteries continues. History so far: Bought 13 Optima BlueTops. 2 were bad and had to be shipped back for replacement. The 2...
Okay, while fiddling around with chargers on the one apparently bad battery, I found that I hadn't tightned the bolt on one battery cable in the string. (Not...
On mine (#220) it's bolted to the plastic wall just uphill of the shunt. - Jake From: sparrow_ev@yahoogroups.com [mailto:sparrow_ev@yahoogroups.com] On Behalf...
... Okay, found the fuses. That's not the problem. There is 166V on the input of the Vicor DC-DC, and 0V on it's output. Looks like having the power "flicker"...
... 151v sitting still is a pretty much dead pack. I'm guessing you mean by "other options" by the other display values on the EMeter. I'd bet that -50 is the...
So, since it seems I've fried my DC-DC somehow, anyone have a recommendation for one to replace the Vicor unit in my Sparrow? (300W or 400W, not sure which)...
Lots of people on the EVDL seem to recommend the Todd RV Battery Charger as a good DC/DC converter. Its AC inputs can run on DC for a 156V nominal pack. I...
John, All the batteries I just put it in it have been load tested and charged while they've sat and are all in good shape. Could this indicate that atleast one...
John, Message 20660 has a link to a site selling Iota's for 120.00 I have not checked to see if the sale is still going. The 30amp is working well. If I had...
Does anyone have an extra zivan n3 charger for sale, I am installing my lithium polymer battery pack in my sparrow #55 and will have to send the charger to be...
Jake, Before I started tinkering around in the controller area, I found that the emeter said my voltage was 151v. John said that this indicated a dead pack or...
... All this sounds odd. A) The voltage at the Emeter won't (at least it shouldn't!) change if the car is on or off. (at least, not be 10V!) B) 161V is still...
"The voltage at the Emeter won't (at least it shouldn't!) change if the car is on or off. (at least, not be 10V!)" The voltage on the emeter doesn't change...
John, he's not reading voltage from his e-meter in the text below. He's doing what I suggested, using a hand-held DVM. It sounds like you blew the main fuse....
... Which is rather odd as well. Fuse could be blown, and you are just reading leakage current through the rest of the system. Fuse resistance should be 0 as...
I've been looking up a replacement Vicor DC-DC. In the archives it says that Sparrows use a VI-M51-EQ, that is a 12V output model. Why aren't sparrows using a...
... Ah! You're assuming that all Sparrows are built the same! Various Sparrows use various models of DC-DC converter. The Corbin "engineers" were trying to...
... But why would you EVER use a 12V output model? That isn't the right voltage to drive "12v" accessories at any time. The 400W Vicor with 13.8V output is...
... More to the point, if it draws a noticeable current when idle (which is most of the time) it will drain your batteries. ... The Vicor converter in mine is...
If you can buy the same number of watts at 12V as you can at 13.8V, you get more amps. And some of the loads are constant current, leaving more watts for...
Why not just add a small 12V 7Ahr battery. Much cheaper. Add a small 12V low current charger and it will always be full. My sparrow measures about 5A draw...
... And you have dim headlights, slow wipers, and general brownout problems. (As well as needing a 2nd charger - that might fail quietly leaving you with a...
... right > voltage to drive "12v" accessories at any time. ... Pardon my ignorance, but why would you feed 13.8V to 12 volt accessories? Or is this DC/DC only...
... Because that is the voltage most of the accessories are designed to work off of. Just because a car has a "12v" electrical system, doesn't mean it runs at...
A fully charged 12 Volt battery is at about 13.8 to 14 volts. Charge to 12 volts and you have until about 11.5 to see disfunction and 10.5 to be dead. Sparrows...
I'm sorry, but I have to respond to this. How would you be "stealing range?" You're carrying some lead for the traction pack and a little more lead for the...
My Fiero was made in 1992 by Solar Electric Engineering. They set it up running a battery and small charger to run accessories. It works well and doesn't use...
