DIY DC Generator: charge batteries off grid

This broken treadmill has a good DC motor inside. In this video I pair it with a gasoline engine to build a generator that can charge batteries. It was a fun process. I can now charge 12V 24V 36V and 48V batteries. This is useful when off grid and no solar production. --------------------------------------------------------------------------- Amazon Affiliate Links: Victron charge controller, 250/100: https://amzn.to/3Y6aAqX Box, for Din rail mount circuit breakers: https://amzn.to/3jueVW7 125A Nader Circuit Breaker: https://amzn.to/3jyIaHg 16A, DC circuit breaker: https://amzn.to/3HYnYrO Prototype PCB Boards: https://amzn.to/3Y6r0Q8 Hydraulic Crimper Tool for wire lugs: https://amzn.to/3DGFRIR Ring Terminals, UL, cable lugs: https://amzn.to/3Y6aZcX Pulley, V-belt, 5/8" bore 3.5": https://amzn.to/3wXzL3i Pulley, V-belt, 1" bore 3":https://amzn.to/3jslXe3 V-belt: https://amzn.to/3DDlwo4 “As an Amazon Associate I earn from qualifying purchases.” --------------------------------------------------------------------------- 3hp Gas Engine, Predator, 79cc: https://www.harborfreight.com/3-hp-79... -------------------------------------------------------------------------- Choke, Inductor used in video: https://www.mouser.com/ProductDetail/... -------------------------------------------------------------------------- Signature Solar Affiliate Links: 100 Amp battery charger: https://signaturesolar.com/eg4-charge...
