Hello everybody, I have a DIY flashlight I built that uses a 100watt cob led that I am currently powering with a smc 6700 mAh 4s lipo. I was wondering if anyone had any good battery recommendations that might be on the cheaper side. I'm currently getting a run time of about an hour so I'd like to bump up the capacity some maybe to 10Ah if I can. I have looked a little at making my own lipo battery packs but I don't know if that would be worth the effort. Any advice greatly appreciated. Thank You!
