LiPos for my dual BL?

[JOHNNYMAXXIMA]

Well I'm still wanting to go LiPo so I called FMA the other day. I talked to some guy over there and he pretty much said the same thing that MetalMan and Mike had said. I need to get 4 2s packs. The only other thing that he said that kinda confused me (very easy to do) was for me to use this.
I'm not sure if I need that or not, what do you guys think? I read the description on it and still cant quite figure why I would need it.
Thanks.

That is just a connector(series or parallel). No need to use this for your truck. You can make the same thing yourself with wire and solder. Thos ethings are a little bulky.

FMA Direct are releasing their SkyVolt system shortly.Now expected mid september i think.They use the same cell balancing circuitry and charger technology as the scorpion but without the LVC so like the balance pro but in 4s and 6s.The charger charges up to 6s.They'll be available in the 20c Kokam cells.YOu could use a pair of their 4s in series giving you only 2 packs to charge instead of 4.

This is what Greg Covey said on another forum:

" The 4-cell, 3.2AH Kokam packs are pre-wired to a special connector so that each cell can be monitored during charge and discharge for optimal safety, longevity, and investment security. The Skyvolt packs are used in conjunction with Protection Modules; one for charge and one for discharge. This new approach in Lithium cell safety and protection will be available soon from FMA Direct.

The Cell Pro 6s Discharge Protection Module (DPM) can monitor up to a 6s Skyvolt pack to provide a warning when the voltage gets low and use any ESC to pulse the throttle signal to the motor to alert the pilot that it is time to land. There are two dip switches on the DPM but Switch #1 currently has no function. The units will work out of the box without doing any setup, but they perform optimally when you tell the units which way low throttle is using Switch #2 and use the learning procedure mentioned in the manual.

Note that two DPMs can be daisy-chained for up to 12s configurations.

The Cell Pro Charge Protection Module (CPM) is used with any Lithium charger to monitor individual cell voltages and disconnect the charger when the first cell reaches 4.2v. This extends pack life by preventing overcharging. Note that this does not balance all the cells in the pack, only the Skyvolt Charger (not shown) provides true cell balancing during a charge."

So does anybody know if the Scorpion charger plugs into your wall or is it 12v only.
Thanks.

[RC-Monster Mike]

The scorpion needs an 11-15volt power source for operation.

Uugghh.
Are all lipo chargers like this? Why do they do that?
Wouldnt be so bad, but I plan on running at least 2 at a time.
Thanks.

i woulda gotten a trition and duratrax ice chareger. both can charge nimh,nicd,lipo (triton can charge lead=acid). THey both are really good and can work on anything. Its worth the value. For a deceent lipo charger you gotta pay 50 bux.

Can (2) scorpion packs be placed in a series without loosing the LVC device. For example running (2) 2p2s packs in a series, if one falls below the 5.8V limit what happens, would it be unsafe to run with the other pack which is over the 5.8V limit? How do the packs work in a series. I have (3) 1p2s on order for 1/10 scale TC racing, but I am also in the works for a brushless 1/8 scale. I just need to find out what kind of battery set up to run.

[Gustav]

You can run multiple scorpion packs in series no problem.You just daisy chain the LVC connectors.FMA direct have a standard response e-mail explaining the connections.

Is there a Thread about these packs, how other hobbiests are liking or disliking these new lipo batteries?
