Having scored a bunch of high drain Sony VTC4's from Dyson packs I'm thinking of using them to resurrect my NiCd powered 14.4v drill.
Just done and experiment with a lashed together4s pack and all works fine. At 2,000mAh it's already better than the packs it came with (12s 1.2v, 1,200mAh NiCd cells! = 14.4v / 1,200mAh - Yuk!).
Just need a 4s BMS - Something cheap from China I'm thinking.
For charging I'd like to use a cheap wall-wart or perhaps an old laptop power supply. I have one with 20v 3.25A output.Am I right that I need to limit the current that is drawn? What's the best option here?
Thanks
