Solid color modes will use less battery life than strobing/blinking modes.

Batteries are not happy campers!

Unfortunately, if you are planning to wear your whip as a costume or use it at a festival in the summer, the batteries do not last if you are camping, they are designed to be stored at between 20 -25 degrees temperature, and it ruins your costume when they continually go out after about 15 to 20 mins use.

Power and recharge time.

The amount of light that comes out of these is fantastic. I've had multiple batteries for years with no issue.
I do wish there was some way I could recharge these from a USB though so I could do mobile recharges if needed.

Wish these were standard AAAs.

I've had my BitWhip for several years now and the batteries just stop charging after a certain point. I've bought replacement batteries in the past and now I have to buy more, which sucks because they are expensive and you dont get a lot of use out of them.. therefore requiring at least one more backup battery. It would be soooo much more convenient to use rechargeable AAAs instead of expecting people to pay extra for a 'special' battery that hardly functions. I love the BitWhip, but I cant say the same for the charging method.

I've had my whips for about 3 years now and I've purchased batteries twice, and some of the batteries are inconsistent and don't charge. Frustrating because they're literally $5 a piece
