[Feature Request] 1-cell Option (26650/18650)

Recommended Posts

Would it be possible to have the option under the "Baterry" for a 1-cell? For example a 66w 26650 : ) or even one 18650? Don't always need the 200w or 133w, but don't want to sacrifice the Escribe capabilities. Got then 66w by dividing 133w 2-cell option, maybe 75w would be better option?

Here's the original explanation of why the DNA200 won't work on a single cell.

The charger only steps voltage up. The board only steps voltage down, and the internal logic needs at least 5v to run. 

If you run from single cell, which is 3-4.2v, the charger will not be able to control charging, because it can put out a minimum of 4.5 volts. The board would only be able to put out 3v, and at any rate neither system would turn on. 

I'm not saying it isn't possible. I am saying this board can't do it. 

The reference design, with a 3s battery in it, is significantly smaller than a classic Hana, so you don't have to get particularly big to get the feature set. You can even turn the max power down and run a 3s battery that is smaller than an 18650 if you are so inclined. You just can't do it from a single cell with this particular board.
