Electric Flight Packs...



Our electric flight cells have the highest capacities for the lowest weights and will give you the longest flight times. Our packs are made up of aerospace grade, screened and matched cells. Every pack goes through 3 days of testing and our packs are guaranteed to never form a memory.

The nickel straps we use between cells are very special. Besides having a strain relief formed into them, we use 6 welds per strap end. In addition, we use a stack of up to 4 straps between cells for a total of up to 48 welds. The result is the lowest possible pack impedance which will deliver the highest possible current flow.

We make a range of cells from 190mah to 5000mah in both standard and extra low impedance Max series cells. You can order cells loose, screened, tested, and with or without solder tabs. Or, you can order a finished, welded, wired pack with matched cells, less connector. For an additional charge, we can add the connector of your choice.

What's the difference between a Max cell and a Standard cell?
Max cells have a very low impedance which means they can be fast charged at higher rates in a shorter period of time and they can be used in applications that draw more current. The best way to think of it is as two buckets, one with a 1" hose coming out of it and the other with a 3" hose coming out of it. Naturally, you won't be able to fill the bucket or empty it as fast through a 1" hose compared to a 3" hose. Max series cells have 3" hoses.

So, why would you want to use a Standard series cell? Well, Standard series cells tend to have more capacity for a given size and weight. Also, for Park Flyers and Indoor electric flight, Standard series cells give you smaller and lighter cells for a given capacity.

Fast charge rates...
When fast charging a pack, you have to be very careful not to over charge the pack. If you do over charge a pack, the cells can literally explode and seriously harm you and the people around you! For this reason, you should always fast charge a pack outside of your aircraft where you can feel and monitor the temperature of the pack while it is charging. A pack only becomes warm to the touch when it is being over charged. Fast charging itself does not heat up a pack. Only over charging heats up a pack.

Pack voltages...
We typically think of NiCd (Nicad) cells as having a voltage of 1.2 volts per cell. So, if your application calls for a 7.2 volt pack it means you need a 6 cell pack ( 6 x 1.2 = 7.2). We can arrange the cells in any shape you'd like. See the Pack Shape link below.

Connectors...
We stock all of the major connectors being used in electric flight. We can either supply connectors loose so you can install them yourself, or we can install a connector for you for a small additional charge. Sermos and Deans Ultra connectors are $5 each installed. Astro connectors are $6.50 installed. For loose connector prices, see the Wire & Connectors area of the Electric Flight Equipment section of our site.

Special Instructions...
If you have any special instructions for your pack, i.e.- extra long leads, a certain gauge of wire, etc, please indicate these requests on the special instructions section of the order form. 

If you need something different, like a custom shape, or a different number of cells than those listed below, just drop us an email or give us a call.  We'll be happy to work with you to get exactly what you need.
