Непросто было найти крону аккумулятор не на литии.
Не, я понимаю, что ёмкость больше. Я даже понимаю, что кому-то зарядка батареек через type-C может казаться удобной.
Но в гитару такие батарейки ставить банально нельзя - их преобразователи шумят.

So I spent this sunday afternoon doing some field research and soldering in order to be able to drive a #LEGO #train #motor via #ESP32forth using a #L293D motor driver and a nifty #rechargable #9V Lo-Ion #battery that holds a whooping 1300 mAh. I use this to power the #ESP32 (with a #LM2596 regulator) and the motor (via L293D).
And the best thing: the setup works, the code works and yes the motor runs.

Short follow-up: one or two days ago, the battery seems to have been drained enough to stop it from working. It's voltage measured about 2.3V, so still high enough to not damage the battery. I think 5 months for one charge is a very good time.
