Energy systems that
pay for themselves in kilowatt-hours.
Wingzman builds lithium energy systems for India — storage that shaves the demand charge on a factory bill, financed packs that keep an e-rickshaw earning, and backup that finally replaces the tubular battery in the corner of the house.

What we build
Four places a battery earns its keep
The same components — LFP cells, a real BMS, monitoring and a service relationship — solve four quite different problems. These are the four we work on.
Mobility Solutions
Lithium packs and financing for e-rickshaws, 2W and 3WLithium-ion packs for e-rickshaws, two-wheelers and three-wheelers, sold or financed through RBI-regulated lending partners, with IoT monitoring and local service behind them.Explore MobilityHome Energy
Solar, storage and backup that actually fits the houseLithium home storage and solar-plus-storage sized to a real household load — quiet, maintenance-free backup that replaces the tubular battery and the water-topping ritual.Explore Home EnergyEnergy
The analysis behind every recommendationOpen, worked-through analysis of how the energy system fits together — cells and chemistry, grids and tariffs, policy and the money — published in full rather than kept as sales material.Explore EnergyWhy Wingzman
The same engineering under all four
A storage cabinet in a factory and a pack under an e-rickshaw seat are the same problem at different scales. These are the parts we do not vary.
LFP cells and a real BMS
Chemistry chosen for thermal behaviour and cycle life in Indian conditions, with a battery management system that protects cells rather than only reporting on them.
Monitoring as standard
State of charge, health, temperature and throughput, visible from the first day. Degradation becomes something you watch rather than something you discover.
Thermal design
Packs and enclosures designed for 45°C ambient and direct sun, because heat is what actually ends most battery lives in this market.
Financing where it matters
EMI structures arranged with RBI-regulated NBFC partners, so the decision is about whether the system pays back — not whether the cash is available today.
People who turn up
Local installation and service teams. A warranty is only worth what the response time behind it is worth.
Sizing before selling
Every quote starts from a load profile or duty cycle. If the arithmetic does not support the system, that is the finding we report.
How we work
The same four steps, whatever we are sizing
A battery is not a product decision so much as an arithmetic one. This is the order we do the arithmetic in.
- 01
Start with the load
Bills, load curve, outage pattern, duty cycle. Whatever the pillar, the sizing follows from what the site or the vehicle actually does — not from a catalogue.
- 02
Size power and energy separately
kW covers the peak you need to hold; kWh covers how long you hold it. Deciding them together is how systems end up expensive and still undersized.
- 03
Show the arithmetic
What it costs, what it saves or earns, and over what period. If the numbers do not work, we would rather say so than sell around it.
- 04
Install and monitor
Commissioning by people who will still be reachable afterwards, and telemetry on health and throughput so degradation is observed rather than discovered.

Your Motor Makes Torque Two Ways, and One of Them Is Free
A third to a half of a modern traction motor’s torque comes from rotor geometry rather than from the magnets. Understanding where it comes from explains most of what a motor spec sheet is telling you — and why the controller is part of the motor.

The Four Numbers on a Magnet Datasheet, and Which One Actually Matters
Most magnet specifications are read for the wrong number. The one that tells you whether a motor survives a hot fault is usually the one nobody checks — and it degrades five times faster than the one everybody quotes.

Your Unsold Stock Is Ageing: Calendar Loss in Battery Inventory
A fully charged pack in a hot godown can lose 10 to 15 per cent of its capacity in a year having done nothing at all. Two decisions control that, both are free, and neither usually gets made.
