Battery Charger Adapter D Cell to AA Cell

thingiverse

Hi! I'm excited to share with you my lucky find of an incredibly powerful and versatile battery charger, the ISDT C4 - http://s.click.aliexpress.com/e/cdaJDALA. This amazing charger can handle a wide variety of battery chemistries: Li-ion, NiMH, NiCD, and even NiZn! It also supports 14 different battery formats, including 18650, 26650, AA, but unfortunately, it doesn't support D-cell batteries. As someone who owns devices that rely on high-capacity D-cell batteries (up to 6000mAh), I was in a bit of a pickle. That's when I designed this simple adapter to bridge the gap between my charger and these powerful cells. The best part? No tricky soldering required! To build this adapter, you'll need the following parts for the AA adapter side: * 2 M3 x 6mm screws * 2 M3 nuts * 2 washers And for the D-cell adapter side: * 2 M3 x 6mm screws * 2 M3 nuts * 2 washers You'll also need to arrange two small wires around a washer, as shown in the picture. Happy printing!
