What's the best way to attach the temperature sensor to the packs when I'm charging them? I've noticed they're quite a bit hotter (on a temp gun) than what the temp sensor says, which makes me worried I might be getting them too hot.

Also, anything I need to change on the default profile (#1) for 3700's, other than possibly the amperage?

If it's a stick pack, just around the middle, and have the heatshrinked bit go right around the curve of the side of the pack.

Yeah, the heatshrink may provide some insulation to the sensor, and some have stripped that stuff away, but you may risk shorting it with the exposed wires.

Otherwise, it should be good within a degree or two, but if you can test with a temp gun just compare the results, and if you find it's off by 2 degrees, just take that into account when you set the cutoff temp.

I think 5mv per cell is still standard for NiMH, so 30mV is fine. I think battery matchers recommend 120 to 130 degrees cutoff for 6-packs, but quality of batteries may change that variable.

Tom235: Have you checked the voltage of the battery with a multimeter? Also clean contacts help, but I think you've made sure of that.
Have you tried the charger with the car on? (connect it only after you turn the ignition, though) The alternator will provide a bit of a voltage boost.

hey guys anybody try testing the RPM on this and then putting it on a real dyno? I am curious to see if say Motor X has 24000 and Motor Z has 25000 on the APS how those motors compare with RPM on a high end dyno. Like if you see the same 1000 or so difference in the motors.

Just got one from EBAY and found out that a newer version with step charging is coming out Hopefully all the other function is the same as I use linear charging

I have had numerous step chargers, to tell you the truth I think step charging is overrated. I sold all of them, and purchased 2 millineum pros $50 a piece on ebay, for a fraction of the cost. And I saw no performance lost. Actually I was faster than I ever was over the weekend. Most of the time when your at big races sometime or another the power goes out. If your in a middle of a step charge your screwed. so.... in my opinion! dont believe the hype.

Default aps dyno/charger

Several guys have bought the aps dyno/charger at our track and they all seem to like them fine. One guy even has two!!! he just bought 5 new packs and we'll see how this charger does with them over the next couple of months.

From what I understand, the step charge function of the APS is apparently going to be mainly by upgrade for those who know they want it, not necessarily as a retail unit, yet at least. You'd be sending the unit into Magma in Canada for them to swap the BIOS chip.

And, it's still in testing (has a big fat warning instead of a BIOS version when you boot it up), so chances are you'll still have the linear functioning one.

I have two myself, one bought, one won, and I couldn't be happier.

Default Dyno Charge 3 Stage Charging

I have seen team drivers testing the new software since Feb. At first I sneaked a peek while they were charging and saw it displayed cools symbols that never showed on my APS. The driver just told me they were testing some new software for the charger and didn't say anymore.

I guess it's been half a year now and I'm sure they have the software fully developed and tested by now. It's good to hear they will finally release a version for us all. I'd love to have my software upgraded ASAP!

Hopefully its just a software upgrade, as I just paid for a new one and won't be happy if a new model that physical looks different and have more better function than just 3 step charging comes out next month. Can't wait to get mine though.

Getting mine at christmas, along with other stuff.

So what do ppl think of this, is the motor dyno good? Is the charger good? Because i rather spend money on this rather than buying jst a motor dyno, and just a charger.

It's just a software upgrade, it'll physically use the same screen and everything.

It's a great charger, lets me manage my Tamiya Silver-can and Sport tuned motors for our TCS, weed out the bad ones, and tells me when they're broken in too. It may not be a real dyno, but with a baseline reading I can compare them in terms of top speed and efficiency.

My batteries have improved tenfold since switching from an Intellipeak Digital, both in duration and punch, and the temp probe and dyno stand (doubles as a motor soldering stand for me ) are great additions.
