"Tamiya" Connector (continued)
Receptacle of the Tamiya connector system (male side).
MOLEX part number 35141-0201
with pin 35727-0201 |
"Tamiya" Connector
(continued)This is a popular 15 amp connector for battery packs, and is popular with radio control hobbyists.
It is referred to by them as the Tamiya system.
Normally the receptacle is attached to the battery pack.
The 7.2 V and
9.4 V connectors are identical, but the 7.2 V has heavier gauge wire (16 AWG versus 18 AWG) |

The JST is a popular R/C connector, and is well suited for battery packs, containing an internal lock and
a polarized connection.
The female (plug) is usually used on the battery pack. |
|
JST RCY Connector (Continued) Also known in RC circles as the
BEC connector, or the P connector, it is one of the most common connectors for low current applications.

Deans Connectors
Deans doesn't seem to have
ratings listed for these popular RC connectors, but they should be good for at least 10 amps. These are only available from one
USA source--Deans. They are very popular with hobbyists that need a low resistance, high current connector. We have assembled
over 1000 packs with these connectors. The solder connecitons are flat surfaces, we have used up to 16 gauge wire.
The
Female side is usually connected to the battery pack, and the negative terminal is usually the terminal that is parallel to the
long side of the conector. |
