I have one, it gives percentage of battery info to the Epic/Scarlet, lasts about an hour, and has a D-Tap. It's a little lighter than my 160W GMP batteries but the same size. Safe for airline travel, you can carry as many of these as you want. Personally I would go with 160W GMP's. They'll last longer and if you have three you can shoot all day. Less battery swaps, more time focusing on shooting. You can have up to three 300W batteries on a carry on. Two spares and one attached to the gear. I'm assuming that's why you want a 90W battery, for air travel? Can't see much of an advantage for them other than that.
Thanks for the reply guys.. I was going to buy the GMP's but then I came across someone having to pay for repairs because they were using GMP voiding there warranty.. not that it matters to me.. I dont have any warranty. Maybe I will revisit the GMP option.
Thanks
Dean.
Please share the sources or the site for this 3 batt. up 300W.
thanks

I have two that I use for my steadicam and for the Epic when I want a lighter setup (otherwise I use the 230wH GMP batteries). Works great in either. Doesn't show time or percentage tho, just shows voltage. Not really a problem. I haven't stressed them as much as some of the above posts, but they've been 100% reliable for me so far.
Under definition a "large lithium ion battery" is considered to be beween 8-25 grams of lithium content. 25 grams being the equivalent of a 300W battery. You are allowed up to 3 "large lithium ion batteries". source: http://safetravel.dot.gov/definitions.html
I am unsure about the 300Wh. I believed it to be 160 Wh, but that may have changed.... But, the airlines can refuse to let you carry on any Li-Ion battery larger than 100Wh, and alot of them do!
