What Abertax Technologies does
Abertax Technologies Ltd is the Malta-based commercial arm of the Abertax Group of Companies, founded in 1999 by two German nationals and now led by Group Chairman Joseph Cilia. The group operates across three Malta sites (headquarters in Paola, R&D in Mosta, and the 1,600 square metre Abertax Kemtronics EMS factory at Mosta Technopark) and employs over 150 staff, the majority focused on research, development, and innovation.
The company's core business is designing, patenting, and manufacturing battery ancillaries and components for energy storage systems. Its product portfolio centres on four technology pillars: capacitive electrolyte level sensors (CLS and the patented CLS Lite), the e²BMS wireless battery monitoring platform (2.4 GHz MiWi Protocol) and the AMC cloud data aggregation controller, patented gas release valves (GRS) using a unique diaphragm system for VRLA/Gel/AGM batteries, and patented magnetic water inlet valves (MV). The portfolio is held together by patented connector systems (WLW) and complemented by voltage sensors (BVS) and accessories. Abertax Kemtronics provides in-house electronics manufacturing services (SMT/THT assembly, cable assemblies, transformer manufacturing, machining) at up to 80,000 components per hour across four SMT lines, giving the group captive production capacity for both its own products and third-party EMS customers.
Abertax monetises through three streams: sales of proprietary battery hardware ancillaries to OEMs and battery dealers, subcontracted EMS revenue through Abertax Kemtronics, and a newer OBM cloud-monitoring subscription licence with auto-renewing 12-month prepaid terms. Commercial motion is direct enterprise field sales to international battery, industrial vehicle, and machinery OEMs—combined with a multi-continent distributor/channel partner network that includes tier-one industrial battery brands such as Enersys, GNB, Hoppecke, and Banner. Pricing is quote-based with credit terms scaled to order size and a EUR 15 handling fee below EUR 150 orders. The group holds ISO 9001, IATF 16949 (automotive), and ISO 14001 certifications, and over its history has invested EUR 1M+ into lithium-battery products (2019) and launched adjacent product lines including the MicroCHP unit (2021) with the University of Malta.

Product offeringCore offering
Abertax Technologies designs, develops, manufactures, and sells proprietary battery ancillary components and electronic monitoring devices used in lead-acid and lithium energy storage systems. Its core product family spans electrolyte level sensors, basic and advanced (e²BMS wireless) battery monitoring systems, battery voltage sensors, gas release valves for VRLA batteries, and patented magnetic water inlet valves, supported by connectors, level probes, and the Abertax Master Controller (AMC) cloud data hub. Through subsidiary Abertax Kemtronics, it also provides subcontracted electronics manufacturing services (SMT/THT assembly, cables, transformers, machining).
Product overview
Abertax Technologies offers a comprehensive portfolio of battery ancillaries and monitoring solutions. The core product line centers on the e²BMS (Advanced Battery Monitoring System) and simpler BMS (Battery Monitoring System) platforms, complemented by specialized sensors including the CLS (Electrolyte Level Sensors) and CLS Lite for electrolyte monitoring, BVS (Battery Voltage Sensors) for storage monitoring, and GRS (Gas Release Systems) for VRLA battery safety. These devices interconnect with the AMC (Abertax Master Controller) which aggregates data from multiple e²BMS units for cloud-based monitoring and analysis. The product ecosystem also includes Magnetic Water Valves (MV) for industrial applications, and various connector and probe accessories for integration. The company operates in the industrial battery, automotive, and energy storage markets, serving OEMs, battery dealers, and end users globally.

Products and services
- Electrolyte Level Sensors (CLS) Capacitive electrolyte level sensors for flooded lead-acid batteries, with LED indicators flashing green when electrolyte levels are adequate and red when levels fall below the cell plates; protected against voltage/current transients, reverse polarity, and EMI, with a lead-free variant using a carbon-fibre probe.
- CLS Lite Patented energy-efficient electrolyte level sensor that operates between 8-18V using only one connector connected to a negative cell terminal, simplifying installation on flooded batteries.
- Simple Battery Monitoring Systems (BMS) Entry-level battery monitoring system with LED indicators and Abertax's patented battery analysis algorithms, providing battery health information including voltage, temperature, and electrolyte level state.
- Advanced Battery Monitoring Systems (e²BMS) Advanced battery monitoring devices for real-time, on-demand reporting, using RF wireless communication on the 2.4 GHz MiWi Protocol and storing battery data including charge/discharge cycles, temperature, electrolyte low-level duration, and deep-discharge duration for upload via USB or RF to a PC or the AMC central hub.
- Battery Voltage Sensors (BVS) Compact device that attaches to batteries in storage to indicate health by measuring terminal voltage, with periodic slow green flashes when voltage is above the threshold and red flashes when recharging is required.
- Magnetic Water Valves (MV) Patented water inlet valves using a float with embedded magnet that operates a diaphragm-type valve without electrical power, available in domestic (up to 4 bar) and industrial (up to 6 bar) variants for maintenance-free operation in flooded batteries.
