Can the amigo be used to charge unprotected LiIon 18650 INR batteries? Thinking of a 3500mah one.
It has a protection circuit built in, so should be safe with unprotected batteries…

And the product page links to these high capacity batteries.
High Capacity Lithium Ion Battery Pack - Pimoroni
Hope this helps.
Thank you and thanks for the schematic. Looks good.
