This is a rechargeable 7.2 V NiMH battery pack with a capacity of 2200 mAh. The pack consists of six AA cells in two rows and a 4" lead terminated by a “JR”-style connector.


This battery pack comes with 4" leads terminated by a 3-pin JR-style male 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. 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.
