Overview

Leolus Energy is a custom lithium battery manufacturer for consumer electronics OEMs in India. Your product is only as reliable as the battery inside it — so we build ZERA™ lithium battery packs engineered for consistent performance, longer runtime, and zero field failures.

We have been designing and manufacturing custom lithium battery packs for electronics OEMs since 2016. From robotic vacuum cleaners and POS systems to Wi-Fi router UPS, headlamps, and electronic weighing machines, ZERA batteries power products that must perform flawlessly — across markets, climates, and production volumes.

ZERA™ lithium battery systems deliver higher energy density, stable voltage output, and uncompromising reliability in compact, production-ready designs — built to meet the performance, safety, and scalability demands of both domestic and export-focused OEM manufacturers.

From compact lithium battery packs for calculators and IoT devices to high-capacity packs for POS backup and robotic vacuum cleaners, our 2026 ZERA lithium battery range in India covers 3.7V to 14.8V (plus 12.8V LiFePO4). Every ZERA battery is rechargeable and cycle-tested — making Leolus Energy both a rechargeable battery OEM and an IoT device battery manufacturer in India.

Why Source from an Indian Lithium Battery Manufacturer

Leolus Energy is an OEM battery pack manufacturer based in Bangalore, India — a single-source consumer electronics battery supplier handling custom battery design in Bangalore from cell selection through pack assembly, and supplying custom battery packs to consumer electronics OEMs nationwide. For brands still importing finished battery packs, a domestic manufacturer is a faster, lower-risk alternative — no customs delays, no currency exposure, and no waiting weeks on a container for a stock-out part.

Working with an Indian battery supplier means engineering support in your timezone, design iterations measured in days rather than shipping cycles, and the ability to scale volumes without re-qualifying an overseas vendor each time. As an MSME, Make in India manufacturer, sourcing ZERA packs domestically also strengthens the local value-addition in your product.

  • Factory-direct lithium battery supply from Bangalore — no importer or reseller margin
  • A domestic alternative to imported consumer electronics battery packs
  • Custom battery pack design in India, BMS configuration, and validation handled in-house
  • Short lead times and responsive local engineering support for OEMs across India
  • Scalable, repeatable manufacturing for production and export programs
