3 Understanding the Battery Pack

3.1 BATT-14AAAPACK Overview

The BATT-14AAAP ACK is a 3-cell to 14-cell configurable battery pack designed to work in conjunction with evaluation boards such as the
KIT33771TPLEVB, the KIT33771SPIEVB, or the KIT33772ASP1EVB. It offers a compact and easily accessible standard battery platform
that connects directly to the evaluation boards through a 34-pin ribbon cable. The BATT-14AAAPACK thereby eliminates the need for
designing additional hardware to connect with a series of batteries.

The BATT-14AAAPACK includes 14 battery holders (standard AAA format, also known as LR3) connected in series, an optional current
sense resistor, configuration jumpers, and a 1.3mm jack for charging.

3.2 Battery Pack Features

The BATT-14AAAPACK features

• 14 AAA battery holders

• 34-pin header compatible with KIT33771TPLEVB, KIT33771SPIEVB, and KIT33772ASP1EVB

• 1.3mm jack serial charging jack (to be used only with proper serial charger and rechargeable batteries)

• 2mm banana connectors

•0.1 Ω resistor for current measurement

• Current measurement configuration jumper

• MC33771/MC33772 configuration jumper

• Protection fuse
