Yeah, it sure looks like mechanical damage. There is even a scratch on the board where it dragged across something. I'm sure I did that at some point. Thanks for the kind offer on the parts but I can probably reuse the existing resistor as it appears to be in one piece. If you think it will...

Yeah, I didn't see it until I took the picture and enlarged it on the computer. My eyes aren't that sharp anymore, lol. Now that I know it is there, I can see it with the naked eye. I can solder, but not sure I can do that fine work. Would definitely need to find a good strong magnifier.

Well, I found the problem when I took the pictures. It really looks like physical damage, I'm just not sure how the heck that happened. One SMD is completely missing, another is hanging on by a thread. Looks to me like they were physically torn from the circuit board. No signs of arcing or...

dfar, that looks like a great BMS solution but is a bit pricey for my application. Sounds like you have a pretty sweet rig though!

Sorry, I should have been more specific. I tested each cell with a handheld multimeter and they all test fine. The pack is well balanced. I checked and doubled checked the continuity of the balance leds with an ohm meter between the cell terminal and the JST connector and they were fine. So...

I'm not really sure what happened. There are no visible signs of damage on the board. The BMS cut power to the controller during a short ride with a full charge. The board shows one red LED. I will post some pics tonight.

I've been off the boards for almost a year (just enjoying my e-bike). Anyway, the Signal Lab BMS I was using on my 16S Headway pack died. I'm riding bareback for now while I look for a replacement. What are people using these days for packs like this?

In for one. Thanks. Interesting that while I was sitting there looking at the page a box popped up offering me a discount of about $2. I took the offer. Worth a try. It said something like "I noticed you've been looking at this page for a while...".

Looks pretty bulky for 130v, 6ah or am I missing something?

As others have said, Headways are a good choice because they can give you the 40amps you need without building a crazy high amp-hour pack for such a small ride. They are certainly bulkier than Lipo but nothing like as bulky as lead-acid. You should be able to hang them in a bag or box...

Gawd, I'm glad I'm not the only one. I road my bike a few times early this spring and then we had about two weeks of solid rains. When the weather finally cleared I discovered that I had left the battery connected to the controller after the last ride. 7 of my 16 Headways were dead. The...

Are they primary batteries? Must be. Edit: Yep, just confirmed they are primary. Dang it!

Our company is changing out the batteries in all of our AEDs so I have the chance to pick up 6 of these guys that are about 4 years old...

You might have a look at the cell_man 15ah LiFePO4s. http://endless-sphere.com/forums/viewtopic.php?f=31&t=14832&start=210 Assembly isn't going to be as easy as the headways.

Agreed Dogman. I wouldn't jump to the conclusion that anything here was done intentionally. I would assume they had the best of intentions unless it is proven otherwise. Sad day for our community.
