Hello,
I recently bought the LiPo battery charger add-on from Pesky products but I am not 100% satisfied and I would like your opinion/advice.
Everything is fine when the microswitch is on: The battery charges if the board is connected to USB and its powers the board if the USB cable is unplugged.
But when I try to switch the board off while connected to USB I am getting a strange error message "USB Accessories Disabled; Unplug the accessory using too much power to re-enable USB devices" (macbook), as if there was a short circuit... Can it damage my Teensy somehow ? What's the worse that can happen ?
I have to say also that I haven't been able to fully charge the battery (supposedly the green led turns red). After a couple of hours the tension indeed reach a plateau around 4.1V (which is what is expected for a battery rated at 3.7V nominal). I stopped because I didn't want to damage the battery but it is a bit annoying if I always have to use a multimeter and cannot rely on the the led to tell me it's done... Not to mention potential damage to the battery, fire, explosions, zombi apocalypse...
Cheers !
PS: I am using a 3.7V 104 mAh LiPoly and a Teensy3.2
