M**T

Nice little PCB booster, and charger.

Both PBC's , the charger, and boost work pretty well.The boost controller I do have a couple suggestions, I'm not sure which version I received for the boost controller though.It looks different from the pictures on the page.My suggestions with the version I received all have 1.8mm holes for soldering, there is a SMD Diode, or Resistor between the Battery holes, If you do a revision it would be nice to have those holes set at a distance so a +/- screw clamp wiring mount could be placed there, or even integrated into the design.Also wondering about output tolerances when using the USB input which should be 5v in.I tried using it to boost a 3.7v 8000mah Li-Po battery, and after dialing in the potentiometer it ran a 5v blower fan just fine, but If I have the battery disconnected it will not run the fan on USB 5v alone.Was just wondering if I was doing something wrong when trying to directly power it with the USB 5v.Usually its operator error when dialing in the right voltages and Pot adjustments, so I thought I'd ask.Anyways its a pretty good design, and when boosting there weren't any heat issues or failures thus far.
