DIY Powerwall Using 18650 Batteries

Why spend thousands of dollars on a Tesla Powerwall when you could build your own – for a fraction of the cost?

This is a question many alternative energy enthusiasts have asked, and it is ultimately what has led hundreds of people to develop their own versions using recycled laptop batteries.

Now that plans for DIY Powerwall's are being shared for free online, several people have created rigs capable of storing far more energy than the Tesla version.

Jehu's DIY Powerwall PCB boards house 7 18650 cells in series for 24v, It allows you to stack several boards using standoffs and it electrically connects one board to the next to scale your 24v battery pack to a recommended max of 50 boards.

Every board includes several fuses and fused balanced leads for individual cell group voltage monitoring and BMS balancing.

Most of the Powerwall hobbyists recommend using 18650 lithium-ion batteries for their projects. The batteries are usually encased in a colorful plastic and can be found inside electronics, such as laptops.

Though it can be time-consuming to source the used batteries, it’s a worthwhile investment according to DIY Powerwall enthusiasts.

A positive effect of the DIY Powerwall trend is that it reduces waste.
