It's pretty basic, just all joined in parallel (all the positives joined together and all the negatives as well)

Great video. I would like to share my setup with you. I use the 25v battery from my little E-Bike, through a voltage reducer to 13.8v and then into the TravelBuddy. (Still use cord though!!) This setup can provide full temp for up to 4 hours, but main benefit is it makes TB fully portable both during warmup and in cooking stages. Just a couple Andersons and a plug, (and the voltage regulator that I had anyway) so less than $20 to get working. When I get home I just charge the ebike battery from 240v. Easy.

Fantastic! That's what I'm talking about, I've already got a heap of tool batteries so that's what I use. You've already got the ebike battery so that's what works for you. It's all about using what you're already got to hand and making the best use of that equipment.

All well and good if you're a tradie and have the gear on hand, otherwise $200 worth of batteries makes the oven real expensive. Also if you only have one charger it's going to be a real pain to get ready for the next meal

It's a pretty basic build, the adaptors are from ebay and use a 15 volt step up that'll take a 18v input. I would probably use power diodes on the battery outputs to stop the batteries from trying to discharge each other if one was more charged than another, and drop a fuse on the output from each battery as well.

I upgraded to lithium last year with DC2DC charger. Noticed a huge improvement over the old Optima Spiral. I had be using for years. With 14,4V over 13,9V the Buddy was much quicker to heat. With 15V no surprises. Would not go beyond 15V as Element will surely FAIL. Sill was able to cook 1kg of Potato Wedges in 2.5 hours LOL.

The lithiums are much better than lead acid no doubt, and starting to become affordable as well.

Now there's a thought! I see Makita have just released a battery powered cooler/heater though don't know if it's just a peltier device or a proper compressor fridge.

Many thanks. One request and a question. Could you do a video of the tool battery build. That would be almost as interesting as this one. Also does 15volt power supply to Big Bertha, kill it, from the testing you have done?

@LockyourHubs4WDing

2 жыл бұрын

The "build" was pretty easy, no real tips or tricks. The Big Bertha over says in the warranty not to use a step-up, and the max voltage allowed is 15v. Though I've never let a warranty get in the way of a good time! So I'll check it out.

was wondering if the pies where home deep freezer frozen or camp freezer frozen or in between when placed in the oven/s. Cheers

Home frozen

What about the energy used to recharge the batteries? Yes it obviously cooks more efficiently but is there a true gain in having to eventually wait for the recharge of 4 x batteries.

@LockyourHubs4WDing

2 жыл бұрын

It depends on how you charge the batteries I suppose, using the dedicated 12v charger is more efficient than using an inverter and mains charger to recharge in the field. kzread.info/dash/bejne/p6ONt9eGaK20YZs.html

Is there a way to have an internal prob in the pie and the travel buddy cycles on and off once the determined temp is reached maintaining the temp

That should be pretty simple with a digital thermostat and a relay.

If he used 130w to heat the pies and the batteries are 18v 130/18 = 7.2amps used Assuming each of the 4 batteries are 4amp 4x4 = 16amp 7.2 / 16 = 45% used.

Good test Simon but your math on 3 out of 4 percentages is wrong would've have thought you'd be better than that. Also did you measure voltage at oven in vehicle you say its 14v but is it really?? Also you never accounted for convertor losses in you watt hour usage I would assume they're maximum 90% efficient so there'd be at least 10% more power consumption. Still step up are a better overall improvement

You and your Makita - that's obviously the secret! Seriously tho, running 6Ah compared to say 3Ah would probably make a world of difference to the figures - I know that it does when comparing the torque of a dakka dakka! Or maybe not because of the 15v converter? Cheers.

Other than run time, probably not. It's only around 2.5 -3 amps per battery pack.

Wow, you are a bit of a genius! What happens if you feed it directly from the batteries? My guess is that since the heating elements will die with too much temperature and this thing is temperature controlled, then it will work just fine...(famous last words?)

You're right, though I would have been comparing 15v performance with 15v performance! I wanted to firstly see if it could be done with done with tool batteries and secondly what's the difference between driving voltage and 15V.

Why not just run the oven straight off 18v?
