Retron Energies was founded in 2020 in Patancheru, Telangana, and bootstrapped from there. The cells are graded here, the BMS hardware and firmware are ours, the packs are assembled and thermally validated here, and the software that reads them is written by the same team.
Our Patancheru facility runs cell and pack testing on a Neware pack tester and a Keithley DAQ6510, with thermal and cycling rigs for long-run validation. The digital twin runs against real packs here before it reaches a customer site.
Arrange a lab visitCharge and discharge cycling for modules and full strings.
Multi-channel measurement for the thermal and voltage rigs.
Twin predictions checked against measured cell temperatures.
Module build, BMS integration and end-of-line checks in house.
We are a small team in Patancheru building batteries that people depend on. If you want your work in the field rather than in a slide deck, write to us.
Roles listed are illustrative. Confirm the open positions before this page goes live.
We will walk your site, list what can move to lithium and size the packs.
