Rechargeable NiMH Battery Pack: 4.8 V, 900 mAh, 4x1 AAA Cells, JR Connector
This is a rechargeable 4.8 V NiMH battery pack with a capacity of 900 mAh. The pack consists of four AAA cells in a single row and a 4" lead terminated by a “JR”-style 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.
Our 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 our 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 our Baby Orangutan robot controller.

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.
