just recieved my gardeners backpack, incase my speedcontroller on my wcw one has knackered that one. i will see when the new speed controller is fitted . anyway arrived this morning, on charge now, no lcd lights lit up. they do when you turn power on. ill wait till gharger goes green. i will test it out and let you know if my lid keeps coming off as people have said. it dosent have a tap fitted as on the wcw backpack. i know they charge 4 this but it is better turning the tap off on hose rather than bending to turn power off fully. looks like i will have to order a tap to fit on, i wish they showed this option on there website. hopefully my wcw speed controller does the job and concentrate on that one. let you know how i get on. i always feel guilty sat about but need to charge bp fully.
