32140 battery pack, 32140 super power bank, FPV drone outdoor battery pack

I had 4 idle CASKY 32140 cells and thought of utilizing them to create a 0.2 kWh power pack for outdoor use, which can power for an afternoon

   With a 100W charging board, it can charge phones. I intended to power a Xiaomi fan when going out, and actual tests showed it can run at full speed material cost around 100 RMB

      Note that assembling batteries can cause short circuits and fire, not recommended for those without assembly experience

          It can be charged directly via USB-C, with a measured charging current of 3.5 Amps
