Vapor Minimum Charger


Hi Group

I built a 5* charger for my Kyosho Piper Cherokee and am very happy with it.
Charging time is about 20min.

If there is interest I would make a small production run.

Cheers

what freak said. , I want to just have a pigtail so I can run off a 5v USB OR off of 12v if possible (i'll wire it myself just tell me what one would work).
(also I need an extra little male jst connector for a lipo)

It uses 5V and 300mA / Stage.
So if you charge 5 Packs you would need 1.5 A .

Since any stage is independent of the others, it can charge any cell at the same time, of course the bigger the cell, the longer the charging.
I would not suggest to charge cells > than 300mah.

The connectors are JST on the power side and for the batteries the same connectors like used in the Vapor or Minimum models. Connectors are already attached.

Pricing:
12$ per stage.

So f.e. a 3 cell charger would be 36$

Vapor Minimum Charger


I'm interested, 3 or 4 stage. Why 5v for the source?

Hi FlaBill

I choose the 5V because of the datasheet of the IC. But you can use any power source between 5 and 7 V. Even power from the Usb bus is possible.
