Batteries

Our assortment of rechargeable NiMH battery packs give you variety of options for powering your robot or electronics project. The battery packs use 1.2 V cells, the heights of which correspond to their capacities. The full-sized cells are the size of standard AAA batteries and provide 700 mAh while the 2/3rd-sized cells provide 350 mAh and the tiny 1/3rd-sized cells provide 150 mAh. These packs are well-suited for powering small robots.

The smaller battery packs are great power sources for miniature robots, such as those that might be based on our Baby Orangutan robot controller.

Connectors

The multi-cell packs come with 3" leads terminated by keyed, 2.5 mm two-pin female connectors as shown to the right. These match our 2-pin shrouded male connectors, which come in three varieties: straight, right angle, and right angle extended. The battery pack connectors can also plug directly into standard 0.1" male header pins.

Note: The battery voltages listed in the product descriptions are based on the 1.2 V nominal voltage of the NiMH cells from which the packs are made. The actual voltage will depend on how charged the batteries are. A fully charged cell will deliver almost 1.5 V, so, for example, a “6V”, 5-cell pack can measure over 7 volts after being charged.
