DIY Sony NP-F 970 Smartbattery
Description
Update November 2021: I added parts for a smaller version with only 2 cells, this might be usefull for setups that are supposed to be lightweight. Top and bottom of the baseplate stay the same, only the cellholder, sidecover and case are smaller.. Today I will show you my latest DIY-project - a 3d printed smart-battery in the style of Sonys NP-F series. The biggest version of the NP-F series sets you back around 180€. Since I got plenty lithium-cells that came from my discarded electric longboard, I decided to design these batteries myself. I reverse engineered the sony-mount by carefully measuring the batteryslot on my aperture video-light. Afterwards I created a 3d-model and printed the required parts on my Anycubic I3 mega. After all the components are soldered and tested, the bottom and side-covers are glued to the case to form a protective housing. The housing contains a BMS to make sure the cells are happy. The BMS protects the cells from overcharge, undervoltage or shortcircuit and a balancer-function equalizes the packs voltage levels. So that every single cell stays safe and sound. Now lets talk about the skills and tools required to create the battery! First of all, you need a 3D printer and a soldering-iron. Having a little experience with soldering stuff might come in handy. Furthermore it helps if you know a bit about electricity, red cabels have positive voltage, shortcircuiting is a nono - you get the idea. The case consists of seven 3d-printed parts: There are the two sidecovers and the maincase. The lower and upper baseplate, in where the BMS will reside. Inside the case are two holders for the 6 cells. Everything is easy to print, only the two baseplates need supports.
