Longest Lasting Battery Solution? (8+ hours)

I searched the forum and couldn't find the answer. I need 6-8 hours per day out of my HD10. Do I need to buy multiple 428s and chargers? Canon has that CH-910 you can clip on your belt. Would that be compatible with the DC power cord that came with the HD10? Is there an Anton Bauer solution? Is there a dual or quad charger for this camera's batteries? Thanks!

I personally use 4 428 batteries and will use one battery while keeping the others charged. Each battery has lasted me about an hour so when it dies I throw it on a charger and go to the next. Since each battery takes about an hour to charge I can keep charging and discharging all day. I haven't found a solution for belt packs, or any other brand of external battery since the camera doesn't use a 12v supply but rather a 6.3v (correct me if I'm wrong) which means to use a 12v battery you would still have to carry around a transformer with you.

I bought a 3500mAh on Ebay for like $30. It's suppose to last 4 hours, but I get more like 2-3 hours. The LCD probably drains it faster.

Be careful on Ebay the guy I bought it from tried to scam me with a cheaper battery, but I called him on it and sent it back. They must try and see if they can get people to keep the cheaper batterties...it's almost not worth sending it back because of the shipping costs. They probably make a lot of money "screwning up". I hate that crap.

Anyway, I eventually got the battery I ordered. But, it did cost me almost as much to buy from a dealer.

Mark and Christopher, thanks for the quick replies.

I just learned (by reading the specs) that on AC power the HD10 draws 6.3V and on battery it draws 7.2V.

Something like this would work:

I'm taking my DC power cord to Abt Electronics today to see whether it will work with a Canon CH-910 (with two 4500mAh BP-945s of course) and the HD10.

I need 6-8 hours of battery because I'm following a tour group through Turkey, and I won't be able to recharge during the daytime.

I'm guessing (hoping) two BP945s will get me about 6 hours.

Here is one solution that may help you

Hi Murad.

Here is an article I wrote some time ago that may help you, if you don't mind some minor electrical work (all low voltage naturally).

http://www.playground.net/~winnicki/...folithium.html

I also have used my HD10U for 6 hours straight using a different solution, I will post that solution when I get home.

-Cheers,

Christopher.

Here is an inverter, 12VDC to 120VAC setup

Hi Murad.


Here is the other setup I have used in the past which yields excellent results. 5 ++ hours of recording time on an external sealed lead acid battery, 12V 5 amp/hours.

Here is the link to the web page i have quickly slapped together.

Cheers.

JVC makes one...

According to JVC this battery should last 6-8 hours 5600mAH.

add $50 for the charger.

I guess $50 should be added to the $200 (for the battery) since the original JVC charger can't be used with it.

I think for now I will be using my econo setup.

CDN $30 for dc-to-ac converter.
CDN $6 for 12V 5000mAh sealed lead acid (i bought 7)

(30 + 6x7) x 0.75 = $54 (US)

Total recording (real time) ~7h x 7 = 49hours

http://ottawa.hn.org/WEBSITES/EQUIPMENT/dcac.html
Price to recording time ratio compared to this http://www.jvcservice.com/store/Prod...?part=BN-V856U

$250/8H (supposed 8 hours) ~=~ $54/49H

Final score (lower is better)

31(JVC) to 1(Chris)


-Cheers

Does anyone have any follow up information for this? All of those web sites no longer work.

I'm looking for basically the same thing. 5+ hours...

The sealed lead acid approach is ideal, can anyone post more info?


Thanks!

followup

Patrick, I haven't attempted the engineering feat of Christopher Winnicki, but I became aware of the JVC BN-V856U Troy Lamont linked. I'd probably go for that the next time I had $250 or so to spare for the battery and its charger.

Anyhow I'm up to three 428s, so Mark has me beat by one. If we HD1/HD10 users are lucky, the HD100 will take the same batteries. It'll make the transition just a little easier, and relegate the HD1/HD10 to backup or cutaway wide shot duty.

I used to shoot fishing shows up in canada using a marine battery hooked into the 4-pin connector. We would get 12 hours of use on our camera and 3/4SP decks. (uphill- both ways).
With today's camcorders, you could run alll day long and then some. Course, not too portable...

Long Lasting Battery- Power Multiple Products

Anton/Bauer batteries can be used with this camera. The QR-DV300 system provides the DC input into this camera.
In addition to the longer runtime, this system allows you to power your light, a hard disc recorder or wireless recievers- all from the same battery.

If you want to shoulder mount your camera-- your can use the STASIS system which uses the battery to counterbalance the weight of the camera. The STASIS has a 1/4"-20 mount and can be used on a tripod.

More info at: http://www.antonbauer.com/7_14_gold_mounts.htm

http://www.antonbauer.com/stasis.htm

Products are available for other DV and HDV products as well.
