Heli Packs...

Battery packs for Helicopters fall into three basic groups. For .30 size Heli's choose the 1300 Series receiver pack. It has plenty of capacity to power both your flight system and your gyro. The 1300 Series pack weighs only a little more than an ordinary 500mah pack but it has more than twice the capacity. 

For .40 size Heli's, choose the 1200 Series pack. For larger Heli's choose the 2200 Series pack.

If you're flying an Electric Powered Heli, check the Electric Flight Pack section for packs to power you Heli.

As for battery pack shapes, this is where SR shines. We'll be glad to make any special shape pack you'd like. This goes for the leads, too. If you need a pack to go way up in the nose, no problem. We'll be glad to extend the leads on the pack to whatever length you'd like. 2', 3' or 4' leads are no problem. When we do extend the leads on a pack we use a special, very flexible, 18 gauge wire that's like limp spaghetti. It's important that no physical load be put on the connectors or connections. This special wire absorbs the vibration and shock loads without transmitting them to the system.

Remember, never charge a 1200 Series or larger pack with the 50ma charger that came with your radio. If you do, you will eventually crash! You must use higher rate chargers when you use bigger packs! We have a special series of 4 or 5 cell inexpensive chargers designed to match our packs. Don't take chances by using the wrong charger when the right charger is so inexpensive.

Special shapes or wiring requirements are never a problem. We'll be glad to add any "custom" features you might like. Just indicate these requests on the special instructions section of the order form, or give us a call.

If you need 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.

Listed below are the various Series of receiver packs which are available. Select a particular Series or scroll through the list. If you'd like a printed copy, just hit your browser's "Print" command.

"H" Series cells are NiMH.  Series without an "H" are NiCd.

500 Series

The SR 500 is a special pack. Although it's much smaller and lighter than the usual 500mah pack it has a capacity of almost 600mah! It's a great all around sport pack for everyday use. Click on photo to enlarge or return to pack selection list.

The internal impedance for the 500 Series pack is 10.0m Ω. Click here for details about Internal Impedance.

Sizes are in inches. Connectors are $5 additional per connector. Special wiring and configurations available upon request.

2200 Series

The SR 2200 Series receiver pack (2200mah) is the same size as the 1800 Series pack but it gives you more flying time. If you have a lot of servos or servos that draw a lot of current, this is the pack to choose. Like the 1800 series pack, this is a very heavy duty receiver pack that should be used in the most demanding applications. Click on photo to enlarge or return to pack selection list.

The internal impedance for the 2200 Series pack is 5.0m Ω. Click here for details about Internal Impedance.

Sizes are in inches. Connectors are $5 additional per connector. Special wiring and configurations available upon request.
