About us

Electronics engineering and manufacturing in Pune

Sednoid Technologies Pvt Ltd designs and manufactures electronic products at Chimbali, Pune.

We handle the full product: circuit design, PCB layout, firmware, enclosure and assembly. Most of our work is in automotive electronics, lithium battery packs and industrial automation.

The same team that draws the schematic also builds and tests the hardware, so design problems get fixed before a product reaches you.

  • In-house R&DHardware, firmware and enclosure design done by our own engineers.
  • Built to your specificationTell us the voltage, capacity, size and connector you need. We build to that.
  • Prototype to productionSamples first for your approval, then batch production.
  • Tested before dispatchEach battery pack and board is checked against its rating before it leaves us.
  • Made in IndiaDesigned and assembled in Pune. Support from the same team.

Automotive

Electronics for two-wheelers and EVs

Our automotive work covers three areas: instrument clusters for two-wheelers, battery packs for electric vehicles and GPS tracking units.

45 km/h

Two-wheeler instrument clusters

Digital and semi-digital clusters that show speed, odometer, fuel or charge level and warning lamps.

  • Hardware and firmware design
  • LCD, warning lamp and gauge drivers
  • Designed for vehicle supply, heat and vibration

EV battery packs

Lithium-ion and LiFePO4 battery packs for electric scooters, e-bikes and light EVs. Prismatic and cylindrical cell packs are assembled in-house with busbars and a BMS.

  • Li-ion (NMC) and LiFePO4 chemistry
  • Voltage and capacity to vehicle requirement
  • BMS for cell protection and balancing
GSM · GPS

GPS tracking units

GSM/GPS trackers that send vehicle location and trip data to a server for fleet monitoring.

  • GSM + GPS hardware
  • Vehicle power and ignition sensing
  • Server and app integration
