The idea was requested by Mr. David. Technical Specifications Hi Swagatam. I know it was asked before, […]
Motorcycle Low Battery Over Discharge Protector Circuit
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. […]
High Current Wireless Battery Charger Circuit
