I bought 15 of these charge/discharge protective circuit boards last year and found that they all worked well. I fitted one to each battery in sets of 4 and also bought DX Kapton tape, SKU5442 to insulate them and bind the cells together. I ordered an extra 3 charge/discharge protective circuit boards this time to give me enough to make up another set of 4 cells plus 2 spares.
Buy the DX Kapton tape as well, SKU5442 to help assemble the cells into battery sets. It's great stuff. You also need some heatshrink tubing to protect the entire assembly. I got my heatshrink on ebay but Dx may sell it too.
Well worth the money, especially when buying a large number to achieve the quantity savings.
