AiLi Voltage Ammeter Current Meter

 

I still have not got final approval from the Provincial Government Insurance about plates for my 1980 Comutacar, but am still looking and planning projects.
I saw some reference to these for various applications.

I am looking at the 350 amp shunt, but with my 60 volt system I would be around 2200 AH¡¯s.
The meter is rated at 999 AH¡¯s, would it work with a higher capacity?
Hopefully, I explained my question thoroughly and am not asking too much too soon.
?Thanks again,
 

2200Ah seems pretty unlikely -- that means with 60V you have a 132kWh battery, larger than Tesla's largest battery pack. Check again?

As for the shunt--you will probably want more than 350A capability. If I recall correctly CCars will regularly draw more power than that when accelerating -- though, the shunt can probably handle more amperage for a certain amount of time. See if you can find ratings for it.

Finally, doubt the meter will run higher than 999Ah, because that's probably all the space they have on the readout--but again, you definitely don't need 999Ah unless you actually have a 132kWh battery to put in your CCar :)

I think my math is off, I got to 2200 AH¡¯s, by adding 10 batteries at 220 AH¡¯s per battery.
I just added the AH¡¯s together as the batteries were in series.
I will do some more investigating at add to this.
 

You don't hage a 2200 amp hour pack. If you have 10 220 amp hour batteries
you have a 60 volt 220 amp hour pack. At c-car current they won't give you
220 amp hours anyway, more like 120 if you are lucky. Batteris in series,
volts add, amp hours stay the same. Batteries in paralel, amp hours add,
volts stay the same. 350 amps is low. My c-car would pin the meter at 800
amps.
 

Thanks, I am starting to see the error in my math.
Sounds like this capacity meter is not what I am looking for.
?Thanks for the help.
