Hello All!
I don’t even have a board yet, but here I am building a battery. Super interested in all the things! I bought a bunch of packs to harvest cells. Testing with XTAR Dragon and Opus BT-C3400. So far I am only keeping cells with low IR and those that had at least 2V when freed from their packs. Lots and lots of time involved with that which leaves me time to learn and 3D print stuff…
That said, I have looked at many pictures of @Winfly design and would really appreciate someone to confirm placement of BMS leads. I have provided pictures below.
This 2S3P pack is just for testing as the materials were super reasonable, price wise, to get started. The plan is to evaluate a few different methods and see what sticks. The cool thing is I can print these in 1 hour 15 minutes with a 0.6mm nozzle and layer height of 0.3mm in PETG.
My slicer is estimating a 10S4P pack to take about 6 hours to print which seems really good. I will try the N.E.S.E. version as well just for comparison in print time. There are a few other “solderless” methods I’ve seen on Endless Sphere that I will try as well, with magnets being the most intriguing. Anyway, great forum and thanks to everyone that has shared information and knowledge!
