Lipo-how do you know when.....

Got a multimeter? If so, put the negative lead in the neg. port and positive lead in the balance port and check voltage. Then the positive lead in the pos. port and the negative lead in the balance port. Compare the numbers. You don't have to worry unless it is .02V or more difference. I use the Orion balancer. http://www2.towerhobbies.com/cgi-bin...?&I=LXNNA5&P=7
) that those connectors will not slot through the small port in the underside of the orion platinum packs. is there an adapter than needs to be made or is there one that we can readily purchase?http://www.teamorion-avionics.com/Ce...lancing+System

Hi Sime,
I have a Supernova, and have charged my 4800 Orion with great success. Id say the differences in the voltage readings are as someone else mentioned, just calibration differences. Because I only have one battery, I put it on charge as soon as i get to the track, leave the batt on charge until the next race, use it, then chuck it straight back on charge (4.8Amps) after the race and head out to marshall. It may never get "full" but that really doesnt matter a great deal. The last 15 min or so of charge time it is really just trickling...
One suggestion, get an esc with a lipo voltage cutoff, having said that I ran for 23 min in an enduro (T2, 4800, GTB, 13.5BL), before my battery sensor started bleeping (nomadio sensor radio) so as long as you dont too long, you wont get anywhere near being in the danger zone or over discharging.
After race day, I leave whatever charge is in the pack. That way it is usually at least 50% charged all the time...
The orions are great packs

found this in the orion avionics site and this shows the different adapter cables that come with the balancer. its seems obvious (but then what do i know ) that those connectors will not slot through the small port in the underside of the orion platinum packs. is there an adapter than needs to be made or is there one that we can readily purchase?

Thanks for that Pete. Tomorrow at the race meet, I will have one race with it, then put it back on charge to see how much mah a 5min race with a silvercan uses and then I will charge prolly every second or 3rd race.
The main car I will use it on has a Nosram Evil Brushless ESC with a voltage cutoff so thats all good. If I want to use my other cars in a longer than 5 min race, Ill swap ESC's or just buy another one
Also, with the Supernova, it dosnt give you a cell number option like it does with NIMH batteries, so if I want to balance the Lipo one cell at a tine using the balance port, I cant select "1 cell" on the charger. Will this be an issue in the future?

This should work
http://www2.towerhobbies.com/cgi-bin...?&I=LXRWF8&P=V... of course that's assuming you don't have a balancer already.

Do you have a Scorpion? I was just checking out the specs and I noticed the dial in the center. Is that to set charge rate? If so, how easy does it spin? Before my Ice I used to use the Integy 16x and the dial was way to easy to accidentally nudge to a different setting. I was almost ready to glue it before I decided to replace it. I was never comfortable with it.

you wont need to swap escs over, just dont run it for more than 15 min or so, (if using a silvercan, maybe upto 20min)
Either way AS SOON as you notice a drop in topend or punch, thats it, time to pull over.
The Supernova is an awesome machine and when you set it to charge one cell, it will automatically change the cccv settings so that it charges it upto 3.7v, not pumping it to 8.4v.
you need select a different battery profile(so you dont stuff up your current profile) and then change it to lipo, then select the number of cells (1-4).
I'll be at EPIC on Tuesday night, I'll show you...

a silvercan will use maybe 1000-1500mah during a 5 min race... no issues there

You should'nt discharge lipo's ever.

He means "fully" discharge
