Custom-made batteries for your most demanding projects
The choice of battery is an element that should not be overlooked when developing new equipment. Its characteristics and performance can have a significant impact on the proper functioning of this new equipment.
Active in the battery sector, Helpelek develops customized batteries that are perfectly suited to your new products.
With complete control over the design and assembly chain, from prototyping to pre-production and series production, we support you in creating batteries that meet the technical, regulatory, and environmental constraints of your sector (industry, health, safety, connected sensors, IoT, mobility, etc.).
Why choose a custom-made battery ?
✅ Optimization of the space available in your product
✅ Battery life adapted to your actual use (up to several years)
✅ Energy density, current peak, and temperature range requirements
✅ Choice of the most efficient chemistry (Li-ion, Li-FePO4, Li-SOCl²)
✅ Smart communication (Bluetooth, LoRa, NB-IoT, etc.)
✅ Compliance with current standards (CE, UN38.3, IEC, etc.)
Our approach: co-development, performance, reliability
Every project is unique. That's why we work hand in hand with you from the design phase onwards to offer you a solution that is 100% tailored to your final product, ready to be integrated, tested, and industrialized.
Focus on a recent customer case
An industrial IoT player entrusted us with the creation of a long-life battery with LoRa connectivity for an autonomous sensor deployed in a harsh environment. The result: a compact, robust, and reliable solution with a battery life of over 10 years.
