2 x 12V = 24V

[david farland]

Has anybody researched hooking two Red 12V Li-on batteries together to get a 24V source?

Note: I understand the 'massive' precautions/safety measures when dealing with lithium batteries.
Don't know the Red 12v battery output configuration and appropriate rules for discharge.

Yes. No problem.

No extra precautions necessary other than the discharge current must not exceed that of a single battery. The extra precautions are necessary only if you connect in parallel (to increase the capacity).

I'm looking at 1080p field monitors and the portable ones to date seem 24v.

To make things/chargers simplier, I'd like to stick with Red batteries/chargers (V-mount) and use on monitor solution if practical,
thou I'd guess 2 x12V Red batteries seried up should be within Red battery current drain.
Dave,

Dave,

Remember Red Batteries are 14.4V, not 12V. So, two will give you 28.8V, not 24V, possibly a tad more if freshly charged. You may find that many 24V devices will actually work on a single 14.4 LiIo battery.

The discharge current of Red bricks is at least 5.2A (75W / 14.4V). So, your device should be fine under 150W or less. I have discharged similar batteries with 10A with no fireworks.

Thanks Pawel...good stuff.

Looked at the DT-V24L1DU herehttp://pro.jvc.com/prof/attributes/inst_man.jsp?model_id=MDL101631&feature_id=11.....
which wants 150W which I'm guessing is a tad too much for the battery.

Nah, She'll be right, mate.
