Build a Motorcycle Headlamp Battery Over Discharge Protector Circuit Diagram

A simple motorcycle battery over discharge protector circuit is explained in the following post. The circuit will prevent the battery from over discharging by the motorcycle headlamp whenever the mo-bike alternator is not enabled or is idling in the neutral mode in which case the battery is normally subjected to excess loads via the headlamp bulb. Motorcycle batteries are normally a lot smaller with their sizes and ratings compared to the vehicle and the usage. The main use of the battery present in mo-bikes is for enabling electronic start through a press of the given start button. However this small sized battery also has to undergo further stresses while operating excess loads such as the horn, the indicator lights, the tail light and the brake light. Even though the above loads mostly tend to depend on the motorcycles battery power, these do not affect the battery charge level significantly. The one that truly affects the battery is the motorcycle headlamp, which when switched O...
