Default !!! Is there a GFX Turbo 35 Alternative for checking discharge voltage?

Is there really no alternative to the old Turbo 35 for accurately checking battery discharge voltage? I mean for the love of Pete! Trying or find one takes and act of congress.

An Icharger will check discharge voltage 306d and above.

We don't know anything about it's performance yet.

There was also something called a RMS-1 Battery Dumper, but don't know if it did average voltage.

Negative. It doesn't give solid #s cause of its gradual ramping current you can't accurately get voltage #s

Not sure. I'm not sure what the difference is.


Does anyone know if there is a difference?

A turbo 35 or even an turbo 30 will still discharge and give you the numbers needed. They go for around $40 or less on ebay. The GFX will graph, but on a turbo 35 you can watch the discharge, write down the data and make your own graph or table. You don't even need one that is lipo capable if you watch the battery and don't discharge it down too far or charge with it. Gfx's go for over $150 on ebay.

I didn't see any on eBay. At least not a GFX.

Tekin DIS-350 discharger, if you can find one. It will only tell you the whole pack, not each cell, but has programmable discharge rate and cut off voltage. It also has 3 discharge profiles...linear, pulse, or step (supposed to simulate driving conditions) and gives IR measurement

I'm never letting go of mine.

I have an older Duratrax Ice charger that will discharge up to 10amps. I know you can switch to a graph display as it is discharging and could record time/voltage while watching it. If I recall correctly, you can view the most recent discharge cycle. I don't recall if you can save any of that info in the charger itself.

This charger doesn't have a balancing port built into it, so you wouldn't be able to record any info about individual cells.

I used the prototype at the Snowbirds and it was pretty awesome!!!

Not if you use a 30 amp discharge bank I take readings every minute for 6 minutes and I get good information. I'm sorry I should have wrote that down in my original post.
