How to charge the Ryobi 18v and 40v batteries directly from solar
Thanks for the replies. Unfortunately I do not know anything about the inner workings of the Ryobi batteries (5s, 18650, 14s, etc...). I have considered that it would be easier to connect to an existing system that has solar, a charge controller, deep cell batteries, and finally an DC/AC inverter so I can use the standard out-of-the-box Ryobi …
