Power analyser over 60V?

[monkeychops]

I have a couple of cheap HK power analysers that I use for charging and on the bike to monitor voltage and battery capacity.
They do a reasonable job with my 12S setup.
I'm thinking of upping the voltage of my pack by adding 3S giving me a fully charged pack of 63v. The power analyser I've got, and all the others I've seen seem to have an upper limit of 60V.
So 2 questions:
1. Does anyone know if they work at higher than 60v, say at 63V?
2. Does anyone know if there are equivalents to the HK power analysers that work at higher voltage that don't cost too much?

Thanks in advance!

Try these as a start.

Thanks Greg

To summarise those posts

1. the Tunigy Watt meter should work past 60V a little, maybe 10% or so
2. as should the 'Watts Up' meter
3. the Cycle Analyst is what a lot of people recommend, but costs more.
4. no specific info on the Hobby KIng power analyser.

I guess for a few volts over 60V, it's probably ok.

let us know how far over 60V they work. for the turnigy i know 80V will make them pop. on mine i am fairly certain the voltage regulator blew up. if i can find the right 8 pin regulator i will try to repair mine. i found a voltage dropping resistor on the input to the voltage regulator so you may wanna open up your turnigy and increase that resistor a little too.

Ah I didn't realise the Turnigy Watt meter and HK power analyser were different units.

But yeah, it's probably just luck of the draw, a try it and see situation. Or open it up as dnmun says.
And only charging to 4.15V per cell may help also.

There was also info in there on the PIM meter ($80) and Eagle Tree logger.

Even if they don't pop over the 60-ish volts, then unless they changed the code in them I don't think they'll register more than 63V, I think it was. So when voltage is over whatever their coding limit is,, it will be inaccurate for all readings with voltage as part of the calculation. Wh, Volts, W. only amps and Ah will be unaffected.

Thanks. I charge to 4.1V which for a 15S pack makes 61.5V so a 63V limit is fine.
