Castle CC BEC 2.0
Price: $39.95
Availability: In stock
Item #: CC010-0154-00 -

This is a stand-alone BEC. It's rated at 14A and because the actual output depends on the input voltage (and temperature), heads up before deciding to get it because maybe you get 14-15A, maybe you don't - depends on what you feed it). Our best advice is read the specs and make sure it'll do what you want because after you buy it, you're going to Castle for help, not us! ProTip: there are two major differences between a battery and a BEC for powering the control subsystem of your model. 1st, a...

XT30 M/F pair (qty 3)
Price: $3.99
Availability: In stock
Item #: PDR0110 -

Measuring battery capacity isn't rocket science. We offer this one, which is basically the same as the other two versions for those who recognize what a case that's been CNC-machined of 6061-T6 aircraft aluminum brings to the game. 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
Price: $11.99
Availability: In stock
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. ...
