About that Hydrogen that is produced from over-charging these . . . . anyone ever put that hydrogen into a pressurized system for use as a cooking gas? Or is this . . . . dangerous and laughable>? Buuaahaaha!

Steven, do you have an inverter (make/model) that you are using happily with your NiFe batteries?
>These batteries are pretty awesome. I am indeed learning that it's pretty much impossible to determine SOC from Voltage. I measure the voltage: 15.00V, then I make a bunch of juice with my Omega at >230W .... Wait an hour to account for the voltage-slump to recover .... Check the voltage: 14.99. Lol! A little bit suspect?

>It was also strange on this discharge round.... Since my inverter doesnt work below 11.5V, I'm using a car head-light to trickle drain the batteries down to 10v to complete their discharge cycle. I had this >head light connected for a full 24 hours and checked the voltage (head-light still connected) and it was 10.8 ... So I figured I had a ways to go still, since NiFe still have useful capacity down to 10v. Then I >checked 8 hours later, and the voltage was 4.6v! Woah! .... Hopefully I didn't damage these batteries? Once I disconnected the light, the voltage recovered up to 6v. Then with 3.5 hours of charging off >my 900w panels (All we are getting this time of year), Voltage read 13.5. Seems a little fast for such a strong recovery?

And I'm still buying propane like a chump... Seems >like all the Hydrogen cooking I can find online is someone trying to sell some system with a crazy HHO generator hooked up to a burner.

Wouldn't every off-gridder with batteries want to be doing this? Or is it really only practical with NiFe? Still seems like free heating >and cooking fuel... Why am I the only one excited about this?

It's amazing to listen to these batteries sizzle! And yet a very miniscule amount of water loss. I was able to capture a tiny bit of hydrogen in a balloon and make a tiny explosion.
Meni Menindorf wrote: Impressive! I am more curious than ever to capture this as cooking/heating fuel. I have read that the main issues are Hydrogen's invisible flame, and odorless properties make it risky. But it seems like an outdoor application might be a safe option? If there is a leak, it will not cause any issue.
Now the question is, how do I (safely) add a little pressure to the system? I don't think the batteries would pressurize any container themselves... I am possibly imagining a rigid container with a balloon on it to regulate pressure, like on many methane generators. But ... Maybe a tiny pump would be better? Or... Try to talk me out of my Hindenberg situation here? Haha!
