How can I upgrade my Mould King power supply without blowing it up?

Now I'm sitting and thinking about improving the steering of my homemade, and I'm wondering if it is possible to somehow strengthen, improve the power supply by going to the fablab And ask to solder some more powerful parts, but what needs to be improved in it? And that's what kind of battery you can put there, 500 Mah is not enough at all, and you want more The sharpness of the battery is 45-70c submitted by /u/onitsuker [link] [comments]
