About Rajiv's Expertise

Rajiv began his career as a field service engineer for industrial UPS battery systems, where he developed deep practical knowledge of lead-acid and early lithium cell technologies. As the EV market expanded in India through the 2010s, he transitioned into technical writing, covering the rapidly evolving world of lithium Battery Management Systems for automotive and consumer publications.

His work focuses on translating complex electrochemical concepts — cell balancing, Coulomb counting, thermal management, SOC estimation — into accessible language for operatoDK, technicians, and enthusiasts who need accurate information to make practical decisions.

Rajiv has tested BatBMS extensively across the full range of Grenergy BMS hardware, including the BT-BMS-40A, BT-BMS-80A, BT-BMS-120A, and BT-BMS-200A modules. He has documented the app's behaviour under edge conditions including extreme cold (Manali field testing at -8°C), high load (120A discharge on e-rickshaw packs), and cell degradation scenarios.
