The Texas Instruments bq27421-G1 fuel gauge is a minimally configured microcontroller peripheral that provides system-side fuel gauging for single-cell Li-Ion batteries. The device requires very little user configuration and system microcontroller firmware development.
The bq27421-G1 fuel gauge uses the patented Impedance TrackTM algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (%), and battery voltage (mV).
Battery fuel gauging with the bq27421-G1 fuel gauge requires connections only to PACK+ (P+) and PACK– (P–) for a removable battery pack or embedded battery circuit. The tiny 9-ball, 1.62 mm × 1.58 mm, 0.5-mm pitch NanoFree™ chip scale package (DSBGA) is ideal for space-constrained applications.

Software installer to enable BQEVSW to use MKST-3P-ALT-EV2300
Software manifest
Description:
BQEVSW-MKST-UPDATE software is a software update for BQEVSW (bq Evaluation Software) and BQEASY (bq EV-Easy) to allow it to work with the MKST-3P-ALT-EV2300 MKS Technology alternative for EV2300 communications transceiver. This update installs a program that allows switching the USB transceiver target in software like BQEVSW and BQEASY from/to EV2300 to/from MKST-3P-ALT-EV2300.
The program requires administrator privileges.
Requirements:
Features:
Getting started:
1. Download the software
2. Run the installer and check the option to create shortcuts
3. Run the program using shortcut named BQEVSW-MKST-UPDATE from Start menu/Desktop
4. Allow administrator privilege when/if prompted
5. On the GUI window that opens, select the target transceiver to support and follow steps to switch
6. Connect matching transceiver and start BQEVSW, BQEASY or other similar software.
Note: BQMTESTER-MKST-UPDATE and BQEVSW-MKST-UPDATE both update the same software components. Switching the USB transceiver using any of these shortcuts will also switch it in the other.
