battery is dud – Cree XM-L T6 600lm 4-Mode White Bike Light Headlamp - Grey + Silver (4 x 18650) Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

Pros:
Nice bright light. Reasonable finish quality.
Cons:
Smaller rubber band supplied snapped after 2 days; this was my preferred one since it held the light nice and tight. Battery pack failed to charge, ever. I can't use this lamp at the moment until I get new batteries or fix the pack supplied with this. It appears as if a protect circuit is being tripped during charge; pack measures open circuit when probed. Its possible to run the lamp only for a couple of seconds before it cuts out. 2S2P arrangement of cells seems stupid to me, since there is no balancing of charge at all, especially with 'dumb' charger provided.
Other:
Disappointing to only get 2 days use before having to service this brand new product to get it working.
Bottomline:
Great lamp let down by crappy battery pack.
