"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 connections 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 connector. |
