Thanks for reading and feel free to leave a comment below if you have questions about anything! The larger the battery, the longer the scooter can run on a single charge. While this is an old circuit technique, it is optimized for charging higher voltage lead-acid battery packs, and could be used on other types of batteries as well. Connect the positive terminal of one battery to the negative terminal of the next, and so on, if you're connecting batteries in series. in Mechanical Engineering). "force" energy (amps) into the battery pack. Lead acid batteries are the most common type of battery used in golf carts and other electric vehicles. For Analytical cookies are used to understand how visitors interact with the website. a 2 Higher capacity wet I saw this circuit and your explain. voltage (state of discharge), the easier this forcing process is, so you may see the capacity (25% of battery capacity in amp hours), and not raise a wet battery over Finally, you need to decide on the voltage of the battery pack. The higher the voltage of the charger, the more forcefully those electrons will flow. 97. This is a schematic for building a discrete transistor charger, which can be used to charge NiCd and NiMH batteries: This circuit is designed to charge a 12V battery at 50mA, but it can be easily scaled up to higher voltages and currents with suitable components.
