Pushing the limits of electric cooking

I have all of what you say genny solar propane and yes I use my NuWave induction top whenever I can but not on the hook. You’re gonna kill those batteries.

LiFePo4 and Lithium are two entirely different kettles of fish. LiFePo4 no more risk than lead acid batteries.

Though I have not tried one, it seems a dubious proposition to assume that it can make rice as well as a proper rice cooker. Dubious may be an understatement. Microwave cooking does weird things to texture. Some may not have an issue with this.

Locker drains i assume are at bottom of compartment that said they work fine for propane ( heavier than air) not so much for petrol which is lighter and will rise and be trapped in the locker. KaBoom!

You're thinking of natural gas vapors that rise. Gasoline / petrol vapors sink just like propane.

Exactly, I tried all options and nothing beats the rice cooker. We regularly cook rice while steaming veggies in the same appliance simultaneously.

This is the one for a boat: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

The vapors from nearly all flammable and combustible liquids, including gasoline/petrol, are heavier than air.

seems like updating your gas system would be a lot cheaper than 600 - 800 amps of lithium batteries and all that goes along with it.

correct me if I'm wrong....

I thought most all electric stoves, ovens, etc are 220 v...??

If you're talking home appliances, yes. But countertop stuff as well as things made for the marine/RV markets are often 120v instead of 240. The electric stove on my boat is 120v, for example. It's resistive electric, not induction, with 3x 1100w burners (so it needs a 30A/120V feed to run all 3 burners).

And irrelevant in any case to the OP, who is in the happy land of single phase, 230v, 50hz AC power. God how I hate 110v AC power It's the AC equivalent of 6v car wiring.

Lithium power is good for a lot more than electric cooking! It's how I would do it, if I were building from scratch.

Gonesail, its also a sunk cost for me as I have bought all the kit and am installing it in any case for a variety of other reasons (charging efficiency, longevity, zero maintenance, increased capacity in the same volume, limited voltage drop, etc, etc). This thread is just about making it do double duty for the cooking as well.

I wasn't thinking about adding a water maker. The boat carries 500l and we wont be at sea for longer than 8-9 days on this trip. I might carry some survival desalinators for the eventuality of jumping ship, but I think we can live without a powered system.

[Russ]

Yup re gas fumes I stand corrected. Thanks

Yah it's more that it was a total pain to replace in the middle of nowhere so it was handy to have a backup.

These were all the 'portable' induction hotplates though, a more integrated unit like the one you are looking at would be hopefully a lot more resilient

The Lithium batteries used in computers and EVs is a different chemistry than LFP lithium.
LFP is much less likely to experience thermal runaway and a fire. Also they have much better cycle life expectancy. The downside is that they have a bit less kWhr capacity per weight & volume than the other chemistries.

LFP is coming off patent and Tesla at least will be converting to that chemistry, they will lose a little range in exchange for a battery that may outlive the vehicle.

Most LFPs can support a 1C discharge rate but less is better.

3600W is 300A @ 12v. So if you have 3 - 100Ahr batteries would be OK.

OP indicates he has 600Ahr of LFP so they should be fine.
