Alternative Battery Systems

So I have this pet peeve: If your like me and have a bit of gear, you have multiple battery systems to purchase and maintain. At last count, I have 9+ different battery systems. They are all expensive and have to pack a bunch of chargers. And if I have a larger shoot, I darn near need a person just to wrangle batteries.

For my audio bag, I use a Tekkeon and it works pretty well and has multiple voltages available as well as usb power, but each battery is a unique system in itself. So how about a different take: Make an adapter for a common 12v Li-Ion battery and output with a 4 pin xlr and other adapter types and reduce the different battery burden as is possible, to a common type. As a starting point, look at the 12v Bosch tool system batteries. They are compact and somewhat economical (under $50) and perform really well in that line of tools. You can go down to Lowes and buy them or at any other store that sells power tools. If more reserve was needed, multiple batteries could be run in parallel. Think of something like the BDS system used for pro audio except instead of using AB batteries or NP-1 types, it would use a common and inexpensive power tool battery, pick your favorite brand.

I know that you can also do something like this with Bescor bricks, but you can't remove the battery and replace it on the fly, so I think there is room for something different.

I'm to busy to take this on, but seems ideal for a crowd-fund or possibly someone entrenched in Chinese manufacturing could do this. Coollights comes to mind. Are you listening Richard?

Grant, there is no simple answer to your question, and there is no technical solution I can think of. To start with, the big 3 video camera manufacturers absolutely are not interested in having one common battery standard, just the opposite, they keep coming up with ways to try to lock the non OEM batteries out using both hardware (their own connectors, battery shapes, etc.) and software solutions.
Technically, different devices need different solutions - high power shoulder supported cameras need 14V high capacity batteries (V-lock or AB), smaller size cameras (like DVX100, HVX200, etc.) are happy with much smaller 7.2V batteries.
Power tools batteries are optimized for high loads (huge currents) but do not have the same power density, so a battery of the same size/weight as a similarly sized video camera battery would give you shorter run time by may be 1/3 - nobody would appreciate that.

I'm so glad you read this, since you know a little something about batteries. Thinking about a Tekkeon, they start with a battery of some sort and add a resistor board to obtain the different output voltages. Imagine that metaphor, except the battery would swap out and could use better quality xlr or hirose connectors on the base unit. Even using a more expensive NP1 type battery would be ok, the point would be eliminate having so many different battery systems. Handycams usually come with a battery eliminator which could be used to get power into the cams. Higher end gear usually has xlr or hirose inputs.

Given the proliferation of Chinese batteries, the must be a suitable but common battery that would be suitable.

This issue of multiple of multiple battery systems lights my candle every time I have to add another, it is just stupid and expensive
