Ownership verified by DX Good batteries

Involvement: General (knows how to use it) - Ownership: 1 week to 1 month

Price: starstarstarstarstar

Build Quality: starstarstarstarstar
Usefulness: starstarstarstarstar
Overall Rating: starstarstarstarstar

Pros: These arrived with one at 3.98V and the other at 4.02V. Using SKU# 00936 they charged up to 4.19V when the light turned green. I didn't time it, but this took hours. Both fit the flashlight well without any rattle.

Cons: No complaints so far, especially at this price. Will see how they hold up long term. At this price it would be hard to justify anything else based on my experience so far.

Other Thoughts: Checking the voltage while the batteries were in the charger resulted in a higher reading than the 4.19V. The highest was about the time the green light came on, which was 4.23V. This may be normal. I was unable to verify when the protection circuit cuts off to protect from overcharging and how this would affect the overcharge protection of the charger(SKU# 00936).

Bottomline: Seem to be good batteries, especially for the price.

Build Quality: starstarstarstar

Overall Rating: starstarstarstarstar

Pros: They last for quite a while. I'm assuming the actual capacity is near their rated capacity, which is quite a surprise.
Protected cells? What else to say? It'll 'kill' itself if you do something wrong.

Cons: Have to treat these with care, eg don't reverse them or undercharge and mix cells.
Feels a little cheap too.

Other Thoughts: I'm using these in a WF-600 and a WF-800. Both fit snugly and work well.

Bottomline: You'll need these if you're getting any of the CREE flashlights from DX that use 18650 cells.

Pros: I bought these to use in my MTE SSC P7 torch/bike light. They are inexpensive and do the job with a proviso - see below.

Cons: One battery of the pair is fine but the other doesn't hold its charge. With the 'good' battery I get three or so days pre-dawn riding, say about an hour's use. With the 'faulty' battery I get about 30 minutes.

Other Thoughts: They fit snugly in my MTE torch - not too tight at all.

Bottomline: Excellent at the price so I can't complain about one being sub-standard. I'd take the risk and buy again if I wanted more as other purchasers are happy. Recommended.

Build Quality: starstarstarstar
Usefulness: starstarstarstarstar
Overall Rating: starstarstarstarstar

Pros: Very well made. Capacity is near rated value, they last long in my flashlights. I think best price per power density available.

Cons: Maybe a bit too long. In my trustfire R2 they are pretty tight fit, a little hard to push out. they fit well sku 15561. Plastic shrink tube looks low quality and fragile.

Other Thoughts: 500 characters limit is funny :)

Bottomline: Really good batteries, good capacity, build quality could be a bit better... at $0.5/wH they're the cheapest power source available, mantaining still a really good quality.
