Castle CC BEC PRO
Price: $44.99
Availability: In stock
Item #: CC010-0004-01 -

This is a stand-alone BEC. It's rated at 20A but read the fine print because the output depends on the input voltage and external temperature. We're not slamming a product we sell, just wanting to inform you before you pony up for it and then are disappointed. In theory this puppy is good for 20A. And it gives you two power connections to the receiver (like with our dual-connection battery packs, each is rated at 5A so in the real world, figure on getting 10A into the receiver). Honestly, it's...

XT30 M/F pair (qty 3)

ProTip: connect a 2-wire JR-style lead for NiCd/NiMH packs (which typically don't have a balance connector for measuring individual cells) at the 2-pin port. With regard to lithium-type packs, e.g. LiPo, LiIon, LiFe, and super duty LiFePO4 (A123) because they have a...

Extension, 6SXH-PET AB Clip, 1m, 20AWG

Item #: PDR334 -

Note; the balance extension is expressly made for 6S packs - but - because it's so easy to connect, you can use it with a 2S pack, too. Reason to only offer the one extension is because I was loathe to have multiple SKUs just for 2S, 3S, 4S, and 5S packs when it's so very easy to use this one cord with all the variations. If you insists, we have the snap connector covers for the other configurations if you want to roll your own using this extension as the foundation. ...
