Industrial electronics live in tough places — heat, vibration, dust and long unattended runtimes. Leolus Energy builds custom lithium batteries and backup packs for industrial electronics that keep controllers, instruments and HMIs running reliably in demanding plant and field conditions.

As an Indian industrial battery manufacturer, we design packs for PLC backup, portable controllers, test instruments and embedded systems — with wide temperature tolerance, stable voltage and a BMS built for the long haul.

Industrial Electronics We Power

Test & Measurement Instruments

Stable, long-runtime batteries for portable test and measurement equipment.

PLC Backup Systems

Reliable lithium backup packs that protect PLCs and controllers through power interruptions.

Portable Controllers

Rugged batteries for portable industrial controllers used on the plant floor.

Industrial HMIs

Dependable packs for human-machine interface panels needing uninterrupted operation.

Embedded Controllers

Compact, long-life batteries for embedded control electronics.

Industrial Communication Devices

Batteries for industrial communication and gateway devices in harsh settings.

Automation Controllers

Custom packs for automation controllers and process equipment.

What an Industrial Electronics Battery Specification Has to Pin Down

Most enquiries we receive specify capacity and voltage and stop there. For industrial electronics the parameters below decide whether the pack survives its intended service life, and they are the ones worth agreeing before a purchase order.

ParameterTypical requirementWhy it decides the outcome
Ambient temperature envelope Often 0–70°C inside a panel Control panels run hot. Cabinet interior temperature, not room temperature, is the number that governs cell selection and calendar life.
Vibration profile Continuous, low-frequency, machine-mounted Equipment-mounted packs see vibration every operating hour. Cell restraint and tab strain relief are the difference between a three-year and a three-month pack.
Electrical noise immunity BMS tolerant of VFD and contactor switching Variable-frequency drives and contactors generate transients that upset poorly filtered BMS electronics, producing phantom faults nobody can reproduce on a bench.
Service interval alignment Pack life matched to planned maintenance A pack that dies between scheduled shutdowns forces an unplanned stop. Size calendar life to land inside a maintenance window.
Ingress protection Sealed against dust, coolant mist and swarf Machine-shop environments attack connectors long before they attack cells. Connector choice usually fails first.

Three Mistakes We See Repeatedly

These come up often enough in industrial electronics projects that they are worth stating plainly. None of them are exotic; all of them are expensive to discover after tooling is committed.

1

Specifying at room temperature

A cell rated for 2,000 cycles at 25°C may deliver a third of that at a sustained 55°C panel temperature. Always specify against measured cabinet temperature.

2

Ignoring the fault-reporting path

If the BMS can flag an impending failure but nothing is wired to read it, the warning is worthless. Plan how the fault reaches a human.

3

Treating replacement as a like-for-like swap

Original packs are often obsolete by the time they need replacing. A drop-in replacement has to match voltage, envelope, connector and communication behaviour, not just capacity.

If you are working through a specification and want a second opinion before committing, send it over — we would rather flag a problem at the drawing stage than build to a spec we know will disappoint. See how our custom pack process works.
