I've had battery powered lawn mowers before and the biggest problem I've had with them is keeping them charged. You have to either plug them in or take the battery out and that sucks.
This is one solution to the problem. Install solar panels on the mower and just leave it parked in the sun to charge it.
Here's how I did it!
Step 1: Tools and Materials Needed
- Soldering iron
- Wire stripper
- Volt meter
- Screw driver
- Battery Powered Lawn Mower
- 2 - 12 volt Photovoltaic Solar Panels
- 4 - General purpose rectifier diodes
- Double-stick tape
- Nuts, Bolts & Washers
Step 2: Evaluate the Lawn Mower's current condition
The first thing I did was check the batteries. They were toast so I had to build a new battery pack.
I got four replacement batteries at my local electronic supply for $18.00 each. To keep them as a cohesive pack, I applied double-stick tape between each battery...just like the original setup had.
