Built Around Your Device
Custom Lithium Battery Pack Manufacturer
If the battery you need doesn't exist in anyone's catalogue, that's exactly what we build. Tell us the device — we'll engineer the pack.
Start a Custom BuildSome of our best products started as one-off custom requests. As an Indian custom lithium battery pack manufacturer, we work directly with OEMs and corporate buyers to design packs optimised for a specific voltage, capacity, form factor and operating environment — then manufacture them at our Bangalore facility with documented quality control.
Whether you're replacing an imported pack, building a brand-new product, or scaling a proven design into volume, our engineering team handles it from cell selection through BMS configuration and final pack assembly.
How a Custom Build Works
1. Share Your Specs
Tell us the device, target voltage, capacity, runtime, size constraints and operating conditions.
2. We Design
Our engineers select matched cells, design the BMS and the pack form factor to fit your device.
3. Prototype & Test
We build and test a sample against your requirements — voltage stability, runtime, thermal behaviour.
4. Manufacture
On approval, we produce at volume from Bangalore with documented QC and factory-direct pricing.
What You Can Customise
| Voltage | 3.7V to 60V+ — any series/parallel configuration |
| Capacity | From a few hundred mAh to large multi-kWh packs |
| Chemistry | Li-ion, Li-polymer, LiFePO4 (LFP), semi-solid state |
| Form factor | Built to your enclosure, connector and mounting |
| BMS | Custom protection, balancing, comms (I2C/UART/CAN/SMBus) |
| Volume | Prototype trials through to OEM production runs |
Custom Drone Battery & BMS — OEM / ODM
Drone and UAV packs are the most demanding custom work we do, and they are where a generic off-the-shelf pack fails fastest. A UAV battery has to hold voltage under a high continuous draw, survive vibration and temperature swings, fit an airframe bay that was designed before the battery existed, and report its state honestly to the flight controller. That last part is the BMS — and it is the part most custom drone battery BMS OEM buyers come to us for.
We build the cell stack and the battery management system together, as one system, rather than bolting a catalogue BMS onto a catalogue pack. That means the protection thresholds, balancing behaviour and telemetry are set for your airframe, your duty cycle and your flight controller — not for an average that suits nobody.
What we customise on a UAV BMS
| Configuration | 4S to 14S and beyond (14.8V / 22.2V / 44.4V and custom series–parallel stacks) |
| Continuous / peak current | Discharge path sized to your motor and ESC draw, including take-off and heavy-lift surge |
| Protection thresholds | Over-charge, over-discharge, over-current, short-circuit and temperature cut-offs set to your flight envelope |
| Cell balancing | Active or passive balancing tuned to your charge cycle and turnaround time between sorties |
| Telemetry & comms | CAN, UART, RS485, I2C or SMBus smart-battery reporting to your flight controller or ground station |
| State reporting | State of charge, cycle count, cell-level voltage, temperature and fault logging |
| Form factor & connector | Built to your bay dimensions, mounting, latch and connector (XT90, AS150, AMASS or your own) |
| Chemistry | Semi-solid state (Nexfly), Li-ion, Li-polymer or LiFePO4 depending on the endurance/weight trade-off |
Who this is for
- Drone OEMs building an Indian-made airframe who need a pack and BMS designed around it rather than the other way round.
- Agriculture and spraying drone makers needing high-capacity 12S/14S packs that survive daily field cycling.
- Defence, surveillance and mapping integrators who need documented, traceable, domestically manufactured power.
- Teams replacing an imported pack — we reverse-engineer the mechanical and electrical interface and build a supported local equivalent.
- Delivery and BVLOS operators where predictable state-of-charge reporting is a flight-safety requirement, not a nice-to-have.
Cell Sourcing, Chemistry & Traceability
A custom pack is only as good as the cells inside it. We import and qualify cells from established international manufacturers, then grade, match and assemble them in India — which is how a locally built pack ends up with imported-grade performance and a local warranty, GST invoice and support line behind it.
| Chemistry | Best for | Trade-off |
|---|---|---|
| Semi-solid state | Drones and UAVs where energy density per kilogram decides flight time | Highest energy density; premium cost |
| Li-ion (NMC) | Long-runtime devices, portable equipment, survey drones | Good density, moderate discharge rate |
| Li-polymer | Thin or irregular form factors, high burst current | Flexible shape; shorter cycle life |
| LiFePO4 (LFP) | Solar, ESS, street lighting, industrial standby — anything that cycles daily for years | Safest and longest cycle life; heavier per Wh |
Every pack is built at our Bangalore facility against documented quality standards — cell-level testing, BMS validation and pack-level operational testing before dispatch.
