Budući da litijske baterije zahtjevaju poseban režim punjenja, te ih ne smijete puniti na običnom izvoru napajanja, trebat ćete jedan ovakav punjač. Povoljan, te …

Soldered Support:

On page 3 of the datasheet (https://dlnmh9ip6v2uc.cloudfront.net/datasheets/Prototyping/TP4056.pdf), there is a table showing Rprog values. These are the resistor values for regulating the charging current. On the breakout board, this is the resistor marked 122 on the left side of the charger in the diagram.

u tablici: Rprog su vrijednosti otpornika za regulaciju struje. Na breakoutu to je otpornik na kojem piše 122 na slici lijevo od punjača.
