Battery
Important to source cells from trusted supplier. I now source my cells from DIY500Amp instead of 18650 battery store because the store sells higher amp discharge sells and has great pricing! Choose a flattop cell with at least 20a discharge rate for best results (higher discharge rating is better): https://diy500amp.com/
