Post General power advice (D800 & dew heater)
Hi guys

I'm looking to invest in a power source to run my D800, a DIY dew heater and a Raspberry Pi. Absolute maximum runtime I need right now is 12 hours. I'm looking to start cheap and upgrade as and when necessary. I've seen a lot of talk about the eBay blue batteries but I'd also considered a plain of lead acid car battery. What would you guys recommend as a good starting point and why?

Update: it's worth pointing out that lugging around some serious weight isn't a concern right now (hence car battery as a thought).

cheers, Lewis

Seems I can get my hands on a spare car battery for free so I'm going with this for now. Still open to any advice/suggestions though!

It would be helpful if you put down the amps and maH needed...

Li-poly batts are lightweight, hi-capacity, but still growing up. Also $$$ for a quality charger.
Still need to baby sit them while charging, can explode and catch on fire etc.

Li-ion is good but also $$$. No need to baby sit though.
The blue batts are ok but apparently not great quality and not stated caps.
About $25-$40 for 10,000maH.

Apparently the Anker ones are slightly better?
I'm going to try getting the 42,500maH one for $200... it's like 4.8A
So I can power my heated vest on cold days... 10,000 is $50

Lead acid is heavy :)
Check out those motobatts, AGM. Lighter...

D800 with grip should last a while though no?
