Connector

This battery pack comes with 4" leads terminated by a 3-pin JR-style female connector (only two of the pins are used). The connector is the same as what is found on the most servos and has a 0.1" spacing, so it fits nicely with 0.1" male headers and can plug directly into most RC receivers, servo extension cables, and servo switch harnesses, and custom cables made with JR male connectors or Futaba J male connectors. Note, however, that this style of connector is often referred to as “male” in the RC hobby industry, so please use the picture on the right to clear up any potential confusion.

Capacity Options

Pololu's rechargeable NiMH battery packs give you variety of options for powering your robot or electronics project. The battery packs use 1.2 V cells and are available in several capacities:

Cell Type	Capacity (mAh)
AA	2200
AAA	900
2/3 AAA	350
1/3 AAA	200

The picture to the right shows the relative sizes of Pololu's NiMH battery packs. These packs are well-suited for powering small robots, and the smaller (1/3- or 2/3-AAA) battery packs make great power sources for miniature robots, such as those that might be based on Pololu's Baby Orangutan robot controller.

The smaller, 1/3- and 2/3-AAA NiMH battery packs are great for miniature robots.

Assorted NiMH batteries and battery packs.

Battery pack color may differ from what is shown in the main product picture.

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 NiMH cell will deliver almost 1.5 V, so, for example, a “6V”, 5-cell pack can measure over 7 volts after being charged, and it can fall well below 5 volts when the pack is drained. You will need to charge these battery packs before you first use them. The iMAX-B6AC battery charger works well with these battery packs.
