Solar Charging Lithium Ion 18650s - Part 4, Expansion - 12v Solar Shed

Published at : 23 Dec 2025

I'm still using my PWM lead acid solar charge controller to charge a small bank of 18650 lithium ion cells in the solar shed. Trouble is that it is a small bank.

In this video I look at expanding that bank using recycled 18650s.
