Why Leanwatts

Built Differently,
From the Ground Up.

Our edge isn't just what we make — it's how we make it. Vertical integration, in-house R&D, and a supply chain engineered for Indian OEM programs.

01
R&D-First Platform
In-house firmware and hardware using advanced PFC-LLC and SiC topologies. Customisation is built in, not bolted on.
02
OEM Customisation
Voltage, connector, baud rate, charging profile — every parameter tuned to your vehicle architecture and battery chemistry.
03
Multi-Layer Safety
OCP, OVP, OTP, reverse polarity, surge protection, thermal derating — comprehensive protection baked into every SKU.
04
Made in India
Designed and manufactured in Bengaluru. Enables PM E-DRIVE compliance for OEM partners with local value addition mandates.
05
Rapid Scale-Up
Semi-automated PCBA assembly and a reliable supplier network ensures scalable production with predictable lead times for OEM programs.
06
All-Weather Reliability
IP65/67 rated housing with forced-air cooling. Operates from −10°C to 50°C — built for India's extreme climate diversity.
