How to Choose Connectors and Wiring for Your RC Build
Choose RC connectors and wiring by current, gauge, and cell count. An XT60 connector lists 30A rated and 60A maximum with 0.5 mOhm contacts. A JST-XH balance connector runs 2.5 mm pitch at 3A with AWG 22 wire. Silicone wire runs 10 to 26 AWG and handles -65 to +200C. Match the gauge to the current first.

Which connector carries battery power?
XT60 connectors carry battery power on most RC builds.
The XT60H set lists a 30A rated current with a 60A maximum.
Contacts are gold-plated copper at 0.5 mOhm on DC 500V.
The housing runs -20C to +120C and lasts 1000 mating cycles.
The set suits 12AWG silicone wire and costs $11.87 for 10 pairs.
Which connector fits balance leads?
JST-XH is the balance connector on most LiPo packs.
It runs 2.5 mm pitch at 3A with AWG 22 wire on 250V.
It takes AWG 30 to 22 wire and runs -25C to +85C.
Balance extension leads run 20 cm of 22AWG from 1S to 6S.
The 1S lead costs $7.37, and the 6S lead costs $10.65.
What wire gauge fits the current?
Match the wire gauge to the current before you solder.
The PowerStream table lists 12AWG at 41A and 14AWG at 32A for chassis wiring.
It lists 16AWG at 22A and 22AWG at 7A for chassis wiring.
Silicone wire runs -65C to +200C in 10 to 26 AWG.
The 10AWG 2 m length costs $17.99, and the 24AWG 2 m length costs $4.99.
How do you join two packs?
Wire two packs in series to raise voltage at the same capacity.
Wire two packs in parallel to double capacity at the same voltage.
The series cable costs from $17.64 and uses 10 cm of 12AWG wire.
The parallel splitter costs from $8.49 and uses 10 cm of 14AWG wire.
Use two packs of the same cell count for a series or parallel pair.
How do you switch receiver power?
A receiver switch cuts power without unplugging the battery.
The JR and Futaba switch costs $6.99 in 2-wire and 3-wire options.
It adapts JR to JST plugs on cars, boats, and planes.
The XT60 switch harness costs $11.99 on 14AWG wire.
It puts an XT60 female on one end and an XT60 male on the other.
What kit covers small wiring jobs?
A connector kit holds the housings and terminals for custom leads.
The 500-piece JST-XH kit costs $12.72 with 2, 3, 4, 5, and 6-pin housings.
It holds 320 crimp terminals and through-hole pin headers.
Match the pitch on your boards and packs before you order.

How do you solder an XT60 connector?
- Slide a piece of heat shrink onto the wire first.
- Tin the wire end and the connector cup with solder.
- Heat the cup and feed the wire in until the solder flows.
- Hold the wire still until the joint cools and turns shiny.
- Slide the heat shrink over the joint and heat it to shrink.
- Tug the wire once to check the joint before you plug it in.
