Stan 1030 mAh Li-Ion for HX150

tonight we'll show you how to charge a 19-6 50 sale or any single one s lately my and Barry pack directly using a five volt solar panel so there are many electronic devices that have non removable batteries so cannot pull out the battery and charge it with my charger plus with a solar panel like this I can just these devices when totally off the grid so this solar panel I have here has 10 cells in it each cell produces about half of all actually it's a bit over half of once so 10 cells we do a little bit over 5 volts so when not under load the open circuit voltage is about 5 point 4 volts the short-circuit current is zero point 13 amp and when under load this panel produces about five point one five volts so in order to charge the lithium-ion battery pack I need to really use the load voltage down to four point two volts and I'm going to do that by using just a series of resistance and
