Re: Gauge Number from eBay ---- Wiring question, about 24 volt and "bridges" -- update for today

to me it looks like it's designed that full amps would run through that, but it is limited to 10A.
I bet there is a low ohm resistor in there calibrated with a voltage gauge to display as current.
Not sure what your peak running amps is. You could bypass it with a switch for sure, then just switch the ammeter in when you want to check. That would prevent it having to tolerate all the current and heat.
Heat is a function of amps in a device like this, so it's limit is going to be heat dissipation and overheating, so if you only switch it in when needed, it will survive a lot more. Perhaps it will be willing to read higher amps, but if you put 20 amps through it I bet it will blow after a few mins. It's all about cooling and time. If the resistor is inside the plastic enclosure it will not get much cooling, you could cut the back open if you wanted to cool it more. even add a heat sink to that resistor.
If you're using up 4 of those full batteries in 8 hrs, that would be one per 2hrs, ~500Wh/ hr. at 24v. =20 Amps, does that sound right?
