GWS flight packs
 

Good Morning All,

I am new to the electric stuff and I have a few questions... I purchased a GWS flight pack this weekend... It didnt have a manual so I am wondering what is MAX amperage and voltage I can safely run through that tiny little speed control?.... I just purchased a Wattage Live Wire this weekend and it requires a 30 amp speed control.. I do have one, but I would like to keep the weight down as much as possible. Any imput would be great....

RE: GWS flight packs
 

There are a few different flight packs, which model # is your speed controll?

RE: GWS flight packs
 

The part # for the kit is GWS2095 and it looks like it is a ICS300 listed on the discription on the box.... the controller is at the house and I just have the box with me at work so I hope that is correct... You replied to an earlier question about calculating the MAh on a battery pack... I am hoping that I can make 2 flight packs from the Dell Laptop battery pack... If so I will have 2 11.1 volt 1900Mah pacs for minimal cost...

Depending on what Dell laptop battery you are using I assume a newer one that is lithum Ion to get the 11.1 and 1900 mha rating.

the way they wire the pack for the laptop is to take a series parallel combination to gain overall current and voltage

the 11.1 seems to tell me that they are using 3 cells parallel and the 1900 rating is mostlikly due to the pack having 6 cells each 3 cell set is rated at 800 mha to be a combined serial set up of 3s2p

I have seen this setup in dells before.

The main problem with these cells is thier fragile ness if you simply tap one with a sharp obiject it will bleed out its fluid.

Actually i taped one with a xacto knife while remoing some tape from a cell and the cr*p went everywhere. Skin and Eyes need to be flushed it was burning so much. and I have no problem with castic products but that stuff was bad.

Be carfull or spend the money on the newer LiPo packs and chargers thay are safer (I own a PCW with about 100 crashes on it) and no damage to my Bat Packs..

Good luck and be very carfull but most of all have fun.

You can look up the ratings on GWS parts at http://www.gws.com.tw. The ICS300 is rated for 8 Amps continuous and 12 Amps surge, 5-8 cells.

An 11.1V Lithium pack will burn the controller out. 11.1V Lithium packs are comparable to 10-cell NiCd or NiMH. Obviously, 10 is more than 8, and cell count (aka voltage) is critical.

Thanks for the input guys!.. Would it be possible to put a small/light voltage regulator on a homemade 11.1 volt pack and be safe?.... I have access to tons of high end laptop battery packs that are not even in production. We have to "destroy" them as part of our agreement with Dell. I am new to the whole electric model craze that is going on and I am very intriuged by the whole process...
Back to the battery questions though.... Are there ESC's out there that can handle 11.1 volts safely, and what about a charger for said pack? All the laptop batteries that we get have either 1.2 or 3.7 volt cells. The cells I was thinking about using came from an 11.1 volt 3800 Mah pack using 6 cells.. I was under the impression that 3 cells are serial and there are 3 cells piggy backed on those in parallel to get the Mah of 3800... Meaning that the 3 cells in series would be 1/2(1900Mah) the total rating of the whole pack.. Seems like the more I learn, the more I am beating a dead horse when it comes to using these laptop batteries... Bad thing is, I see Li-poly engineering samples coming through here and we have to destroy the pack itself but we can do whatever we want to with the cells. I am just dying to make something work!
