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...

4-tap (Power Expander XD)
Price: $9.99
Availability: In stock
Item #: PEXD -

We call this thing a 4-tap because it literally lets you add another pair of Dupont discharge connectors to one of our batteries (total 4) via the XT30 discharge connector. - XT30 female close up reveals male pins - but - it's the housing that determines gender So why add an PEXD (XT30-DupontX2 power expander) to a ProModeler B2S-series LiIon battery pack in the first place? These packs range in capacity from 850-6000mAh and are a handy way to power something other than a receiver and servos -...

Adapter, Power, Hydra
Price: $14.99
Availability: In stock
Item #: Hydra -

This power adapter is what you need to power a HV steering servo separately from the 6V radio system without burning up the receiver/ESC. - This adapter gives the servo 10A of HV while the receiver runs on a BEC Background: The stock TRAXXAS radio system operates on 6V. The 6V-receiver is backfed through the throttle lead coming from the ESC (through what's called a BEC-circuit). BEC stands for battery eliminator circuit and ESC means electronic speed control, or throttle (for the propulsion...

Power Adapter XT30-XH2 E-Revo Traxxas dual steering servos
Price: $9.99
Availability: In stock
Item #: XT30-XH2 -

The power adapter makes pulling power from a 2S pack's JST-HX balance port and converting to an XT30, easy.  This mates perfectly to a JST-brand XH connector (used for the balance connection of a battery pack). There are other types of balance connectors, battery folks use whatever flavor suits them. Thunder Power, for example uses one, Hyperion uses another, Traxxas uses another, etc. This one is for the JST XH connector. They exist on batteries to make it easy to bleed off voltage from...

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...
