Introduction: Rechargeable Weedeater Trimmer Solar Hack
All brands of rechargeable trimmers have a battery life issue because they need to remain lightweight. Over time the charge controller board does not allow for a good deep battery charge so they only last a minute. You can find them at yard sales all the time. If you have a spare panel with MC connectors this is a fun easy fix. An external charge controller (not shown) can be added for quick solar charges needed in heavily shaded areas. You can use up to a 50 ft extension cord before voltage becomes a problem. Great solution for larger yards far from power. No more burning up electric AC trimmers with 200 ft of cord. I guess you could use a gas trimmer but the exhaust is very bad for you.
