Photon with PIR Motion Sensor powered by USB powerbank

Hi all

It seems that there is an existing issue with sleep mode. You can refer to here: Sleep mode problems on latest firmware (4.7)

Probably I will wait for the next firmware, 0.4.8 to fix it.

I need to look for a suitable USB powerbank with no switch or I can get Lipo Rider Pro with solar kit.

Can anyone tell me what is the brand of battery shield in Electron Solar Kit?

Thanks.
