Jeff don't jump to IDX too fast
 

I've so far got 3hrs fan and 1 hour Drum on my first battery as I've been playing around with my new HD251 and also been reviewing footage, and the battery is now down to about half charge according to the led's, and the voltage is showing about 14.4v. Even if I only get another 30 to 40mins drum hours out of these globalmedia pro vmount 95wh batteries, I think that make them a great buy.
Over here in Australia the IDX 75wh batteries are like $500 each, and the charger the plus pro version is about $800. These shipped from New Zealand cost me like $220Aust each, and the charger $280. I've only had them for a short time, so maybe count that into your evaluation as who knows what long life performance is like.

cheers

Battery Recommendation For GY-HD100U
 

Turns out DSMPOWER is very very busy.
Even more amazing, the US distributor gives off the impression that they don't think there is much of a market for the battery.

After receiving MY DSM-J7472 from H. Preston Media in the UK the other day I immediately plugged it in to my stock JVC charger. Two hours and change later the battery was ready for its first test, a battle of the bands at the Firewater Bar and Grill in Dallas, TX....five bands in six hours.
The DSM-J7472 held up for almost FOUR HOURS without a glitch.
I cannot think of a better $315.00 investment.
I haven't tried out powering my LED obie with the included accessory power jack yet but I will let you folks know how long the battery stays up with the obie turned on next post.

If you aren't ready to go the Anton Bauer or IDX route THIS IS THE battery for your HD100 or 110.

GlobalMedia 95wh battery
 

ok so my final count was 3 fan hours and 2 drum hours on one charge, the last hour was also spent first thing on a cold morning where the battery died quite quickly, maybe in warmer conditions you may squeeze another 30mins out of it.

---Beg pardon there David...any reason why you've appeared to have dropped the effort to make these batteries more available?
I'm convinced that quite a few folks would like to have a better go at it but your site hasn't been updated in quite some time.

Be a good sport and let us have a distributor here in the USA would you now?

Hey Adam are you able to email me the details on your battery set up?

Is anyone using the Series 7 battery system?

Hi Dave Martland here, I own DSM batteries, Sorry for the late reply !!! We tried Empire, but they are mainly in the consumer market and not in professional Broadcast market. Not had any other takers !. JVC can't sell it in the US or Europe, but they sell it outside these countries. Politics !. We are still making the J7472 battery and have a Firestore mount together with a 12V upper circuit to power it from the battery. Of interest to some, we are are working on a reasonably priced high powered solution for the Sony (R) EX3, able to power a light and other equipment. it will include a shoulder mount with a V-Mount battery, and for those without a V-Mount charger, a high quality, low cost plug-in worldwide mains charger with cell balancing function.
