"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. |
