Eric Niemi Posted September 6, 2021 Share Posted September 6, 2021 (edited) Hello everyone, Hope this message finds everyone safe and well. I'm trying to find an easy and affordable way to re-cell my CP16 battery and I think buying TWO of these and stuffing them in the existing battery container might work! https://www.amazon.com/Qsmily-Rechargeable-Connector-Suitable-Aircraft/dp/B08LH66LG7 It looks like you would simply solder the two batteries together in series and then solder to the positive and negative ports in your battery box. Does anyone see a possible problem with this approach? Would it work and still allow use of the original NiCad charger? -Eric Edited September 6, 2021 by Eric Niemi Link to comment Share on other sites More sharing options...
Premium Member Tyler Purcell Posted September 7, 2021 Premium Member Share Posted September 7, 2021 Well, you can't really get the plastic housings apart without destroying them. Which is why people generally just buy re-celled batteries which have new plastic housings. Link to comment Share on other sites More sharing options...
Levi Porter Posted September 7, 2021 Share Posted September 7, 2021 What you’re thinking of doing is pretty similar to what I did. If you crack open one of the original packs, however, you’ll see the cells are side by side vertically, and 16 total cells fit in. So I bought these: 2x Exell Custom 9.6V 800mAh (8xAA) NiCd Battery Pack https://www.amazon.com/dp/B088G27D9M/ref=cm_sw_r_cp_api_glt_fabc_CE4W4R3CT8EY9975PYBK Then I measured the original pack casing, rebuilt it in 3D, and 3D printed a new casing for it. I can share the design with you if you’d be interested. (Possibly print you some too?) For the type of batteries I bought, soldering them in series was the hardest/scariest part, because I had to solder leads to the battery contacts themselves, which is potentially dangerous. If you can find a pack that has leads coming off like in the link you showed, that would be safer. I soldered the leads to little crimpable metal contacts that I hot glued to the openings where the cameras pins enter the casing. Hot glued all the cells in, hot glued the case cover on. Voila. I can add pictures of the finished product when I get to my camera (currently displaced due to Hurricane Ida). Also if I make another pack I can take pictures of the process a bit more possibly.

They look like they might fit in the box but looking at the battery box I can see if I try and pry it apart it will probably all break up to pieces.

Oh nice... yeah for sure share some pics and thanks for sharing your process here ? And no worries on the timetable. Be safe! Thanks a bunch!

Yea you gotta cut it with something to get it apart. I took a little saw and sliced off the bottom. It worked ok, but it never really glued back together again very well. I wound up just buying new ones from Du-All camera. Link to comment Share on other sites More sharing options...
