used my backpack as usual yesterday for about 4 hours
When i got home plugged in the charger and it clicked straight onto fully charged
Niormally would take about an hour plus to charge before the green light comes on.
Anyone else had this? not sure whether its the battery or the charger on the blink.
I have checked all the connections and they are all ok.
Can you discharge the battery without running the pump dry for hours? I could then try charging it.
Thanks all, busy day monday, need a backpack which will work!
