# MAXREFDES1301

The [MAXREFDES1301 reference design](https://www.maximintegrated.com/en/design/reference-design-center/ref-circuits/7580.html) enables quick evaluation of the MAX17852 and MAX17853 for 96V three-Wheeler BMS.

This reference design showcases the capabilities of the MAX17852 and MAX17853 in a daisy chain for the two individual 14-cell voltage measurements, pack voltage, pack current, temperature measurement, and passive cell balancing.

This firmware code example helps to measure Cell Voltages in daisy chain configuration.

### Hardware Set Up

Requirements:

- MAXREFDES1301

- MAX17841EVKIT board

- Battery test jig (Battery pack)

- General purpose micro controller (Arduino Mega 2560) for configuring and communication

- Communication cables and Jumper wire

The hardware connections for MAXREFDES1301 (MAX17852 and MAX17853) with MAX17841EVKIT, battery test jig is shown in image below.
