Battery recommendations for full night...

Offline
#1 lerroy
Hi all

I've been using the eBay Chinese blue 12v lithium 9000 to 20,000mah batteries but finding they are pretty unreliable, slow to charge and dont give me the shooting time I'm after.

I would like at least 8 hours of shooting.

I'm using:

Canon 5dmk3, dp stage 1 slider, emotional tb3.
Backup kit is a 5dmk2 and stage zero and mx2 OG. (this last allot longer)

I'm in Australia and it seems good brand name 12v power banks are hard to get, most won't send overseas.

Does anyone have any recommendations? I've been looking into deep cycle motorbike batteries 7-12ah which seem to be fairly cheap, downside is they are pretty heavy.

Thanks all

We had very good experiences with the RavPower Powerbanks: http://amzn.to/2cvvlL7

I'm having success with TalentCell packs rated at 8,300 mAh and 11,000 mAh. Amazon reviewers who have checked the cells report only ~70% of these capacities, but I find they are sufficient to run my camera and a dew heater (no slider) all night, or lots of consecutive sessions throughout a weekend, in the config I describe below. 

The narrow form factor of these is good for strapping onto tripod legs, unlike my 23,000 mAh RavPower pack, which is great, but as wide as my 7" tablet. 

The TalentCells have dedicated outputs of 12V, 9V and 5V (USB). I'm using the 9V output of the "11,000" to run my D800. (While I've seen others report a need to drop voltage to 7.3V, my dummy battery runs off the 9V just fine.)

I then use my "8300" to run my Dew Not heater (12V output feeds directly into a "Dew Heater Adapter Cable") as well as a TP Link 3040 (via USB). 

In theory (according to TalentCell) I could run all three off one unit concurrently. I haven't tried this.  

I see Amazon reviewers report that the 12V output isn't regulated -- it starts at 12.6 V and drops quickly to 10.5 or so. Thus far, however, this has kept my Dew Not sufficiently warm to combat some fairly dewy conditions on my fat 14-24 lens, and at slow battery drain. So I figure this cheap battery is saving me dosh and bulk and weight on a fancy rheostat controller as well Smile
