How to Choose Silicone Wire for Your RC Battery Leads
Choose silicone wire by gauge, length, and temperature. The wire runs -65 to +200C in 10 to 26 AWG with tinned copper strands. A 12AWG roll costs $19.99 for 20 ft and carries 41A in chassis wiring. A 22AWG roll costs $11.99 for 45 ft and suits signal leads. Match the gauge to the load.
Quick facts
| Fact | Value |
|---|---|
| 12AWG roll | 20 ft, 41A chassis, $19.99 |
| 14AWG roll | 20 ft, 32A chassis, $15.99 |
| 16AWG roll | 20 ft, 22A chassis, $14.99 |
| 22AWG roll | 45 ft, 7A chassis, $11.99 |
| Temperature | -65C to +200C, tinned copper |
| 10AWG, 2 m | 55A chassis, 5.5 mm OD, $17.99 |
What gauge fits a battery lead?
Match the gauge to the current the lead must carry.
The table lists 12AWG at 41A and 10AWG at 55A for chassis wiring.
The table lists 14AWG at 32A and 16AWG at 22A for chassis wiring.
An XT60 connector lists 60A maximum, so feed it with 12AWG or 10AWG.
The 12AWG roll costs $19.99 for 20 ft, and the 14AWG roll costs $15.99.
What makes silicone wire different?
Silicone wire stays flexible from -65C to +200C.
It uses tinned copper strands in red and black.
The 10AWG wire holds 1050 strands at 0.08 mm with a 5.5 mm outside diameter.
The 12AWG wire holds 680 strands with a 4.5 mm outside diameter.
The 14AWG wire holds 400 strands with a 3.5 mm outside diameter.
Which length fits the job?
Pick the length that reaches from the battery to the load with slack.
The 12AWG, 14AWG, and 16AWG rolls give 20 ft each.
The 22AWG roll gives 45 ft for signal wire and accessories.
The 10 to 24 AWG lengths give 2 m, and the 26AWG length gives 4 m.
The 10AWG 2 m length costs $17.99, and the 24AWG 2 m length costs $4.99.
How do you pick wire for signal leads?
Signal leads carry little current, so thin wire fits.
The table lists 22AWG at 7A and 24AWG at 3.5A for chassis wiring.
The 22AWG roll costs $11.99 for 45 ft and suits receivers and accessories.
The 26AWG 4 m length costs $6.38 for small signal runs.
Use 22AWG or thinner only for signal wire, never for battery leads.
How do you join wire to an XT60 connector?
Solder the wire into the connector cup and seal it with heat shrink.
The XT60 extension uses 14AWG wire and lists 30A with 60A instantaneous.
The XT60H set suits 12AWG wire and lists 30A rated with a 60A maximum.
Slide heat shrink onto the wire before you solder the joint.
Heat the tube until it shrinks tight around the joint.

How do you cut and strip silicone wire?
- Measure the run and add 2 cm of slack at each end.
- Cut the wire with sharp cutters for a clean end.
- Strip 5 mm of insulation from each end.
- Twist the strands tight so none stick out.
- Tin the stripped end with solder before you join it.
