Finally got my replacement solarstorm battery, postage took AGES so I gave up and ordered a second(third) full set pretty much for the battery and some spares. Unpacked it last night and noticed the charger was heaps smaller, cool I thought new design, not going to blow up. No, its 4.2V, checked the battery pack - same. Looked at the lights, turned them on and they cycle through hi-med-lo-strobe1-strobe2-off and don't have the logo on top. Ripped off, after reading that some have a different voltage I read the info in the ebay add closely, sure enough should be 8.4V and the pictures show a logo. Annoyed email to supplier - see what happens. Will be asking for money back as falsely advertised, meanwhile the replacement battery shows up too.
I do not recommend this item:
Skyray Solarstorm 2X cree ...
Appears I should have checked their feedback, it's pretty ordinary.
Edit: and when I plugged it in to charge... Bang, fizz, no more charging.
