QUESTION:
What the difference is between the various units(c2,c2.1 H and E)?

ANSWER:
All three models use the same housing, mount and charger. The difference is in the optics and electronics (where it matters most). Here is how our product line breaks down:

C2: Original model using Luxeon emitters, 185 Lumens, 4 hours
C2.1-E: Same as the C2 but with upgraded Cree emitters, 275 Lumens, 5.5 hours
C2.1-H: Upgraded Cree emitters with a more aggressive current controller. 360 Lumens, 4 hours

QUESTION:
What is your return policy?

ANSWER:
Returns are accepted within 14 days from date of purchase in new condition

QUESTION:
How do you get such a short charge time? Does the battery only get a partial charge?

ANSWER:
To answer the first question, there is a big difference between Lithium Ion and Li-Poly batteries. BR Lights is, to our knowledge, the first manufacturer to introduce the Li-Poly battery to the bike light industry. The charge time, and weight, are a direct result of this implementation. Charge time is decreased not because the cells are partially charged, but because our battery pack is charged at a 1C rate. Not only are our Li-Poly cells capable of a higher charge rate than conventional Li-Ion cells, but by using more cells with a lower capacity , we are able to obtain the same overall energy capacity and provide a savings to our customers by utilizing a smaller charging system. There are many resources on the web that will corroborate this, Wikipedia's explanation of the difference is quite good. http://en.wikipedia.org/wiki/Lithium_polymer

QUESTION:
Will the battery last longer if I keep it charge all the time?

ANSWER:
The new Li-Poly batteries are very different from the old NiMH, NiCd or even Li-Ion batteries. These new batteries don't need to be charged immediately. For long term storage (several months or more) they actually preferred to be stored with only a partial charge. Storing the light partially charged is the best habit but occasionally leaving the battery full or empty will not effect the cell life.

A second factor in battery life is depth of discharge on each use. Our batteries are rated at 500 cycles of 100% discharge. This means that after 500 cycles the pack will be capable of supplying 75% of its original power. If the user only runs the pack down 50% each use the pack life will be greatly extended. KoKam has a good web site explaining this behavior of Li-Poly batteries. http://www.kokam.com/english/product/kokam_Lipo_01.html You can see how the cell life for 1400 charge rated cell can be extended to over 3000 cycles if the pack is taken to 80% discharge each use. In short keeping the number of full 100% discharge cycles to a minimum will increase the batteries life.
