About battery spec

[tonywang]

I found two types of 18650 batteries, one is 3.7v the other is 4.2v, which one should I prepare for a uConsole?

[yatli]

Same thing? 4.2v is the charging voltage while 3.7v is the nominal voltage.

[tonywang]

I don’t think so, many sellers marked explicitly about the two specs.

I think that’s exactly what yatli said.

@yatli

4.2v is the charging voltage while 3.7v is the nominal voltage.
