Li-Ion battery pack Answered
I have 4x PANASONIC CGR18650CG LI-ION BATTERY 2250mAh 3.7v. I have connected them in series and it gives around 14v. My internet router is working on 12v 500mA. Is this battery pack too much for that router? I was thinking to use that battery pack as backup for my router when there is no electric power, because it's winter and every few days there are problems with power. Thanks!
