New tiny waterproof digital voltmeter
In building my A123 packs, I needed a quick way to determine the total pack voltage. I plan on using a pair of Cell-log meters that can monitor up to 8 cells per meter, but I also needed a meter to tell me total pack voltage. This one seemed perfect for the job It's very compact, can be panel mounted (mounted flush to the surface of the case and is waterproof. The LEDs are red so should be highly visible day or night.
You can see them on eBay here. I paid $5.25 shipped.
