Sub Process_Globals
   Public Serial1 As Serial
   Private Timer1 As Timer
   Private VCC As UInt 'ignore
End Sub

Private Sub AppStart
   Serial1.Initialize(115200)
   Log("AppStart")
   Timer1.Initialize("Timer1_Tick", 1000)

Private Sub Timer1_Tick
   RunNative("GetVCC", Null)
   Log(VCC)

#if C
 ADC_MODE(ADC_VCC);
void GetVCC (B4R::Object* o) {
   b4r_main::_vcc = ESP.getVcc();

For concurrent charging and use, I use a board that handles all the protection & charging between battery, charging source & device. Like this: https://www.ebay.co.uk/itm/Lot-PCS-...Module-/273431981681?var=&hash=item3fa9d0ee71
(Select the model 'With Protection')

Effectively, this is a UPS set-up
