A Hawker Multi Voltage Charger is an industrial-grade charging system designed to support 24V–80V lead-acid and lithium-ion batteries. It uses adaptive algorithms to detect and adjust voltage/current based on battery chemistry, ensuring safe charging for forklifts, telecom gear, and renewable storage. Features like temperature compensation and multi-stage charging prevent overcharging, extending battery lifespan by up to 30% compared to fixed-voltage units. 24V LiFePO4 Batteries
What voltage ranges do Hawker chargers support?
Hawker multi-voltage chargers typically handle 24V to 80V systems, covering common industrial battery configurations. Their auto-sensing tech identifies voltage needs within ±1% accuracy, preventing mismatches. A modular design allows quick adaptation between lithium and lead-acid profiles via dip switches or CAN bus.
These chargers operate across a 100–240V AC input range, making them globally compatible. For example, a Hawker 40A model can charge a 48V 200Ah LiFePO4 forklift pack in 5 hours while switching seamlessly to a 36V lead-acid system without manual adjustments. Pro Tip: Always verify the charger’s maximum output current—exceeding 0.5C (50% of battery capacity) may degrade lithium cells. Technical specs include:

How do adaptive charging algorithms optimize performance?
Hawker’s algorithms use constant current-constant voltage (CC-CV) with pulse-mode balancing. They adjust charge rates based on real-time temperature readings and voltage dips, slashing sulfation in lead-acid by 40%.
For lithium packs, the charger initiates a “top balancing” phase after 90% SOC, equalizing cell voltages within 20mV. But what happens if cells are severely imbalanced? The system triggers a recovery cycle, discharging high-voltage cells through resistor banks. Practically speaking, this prevents premature BMS shutdowns in cold environments. A telecom tower using Hawker chargers reduced generator runtime by 60% thanks to precise charging windows synced to solar availability. Pro Tip: Update firmware annually—new chemistries like LTO may require profile tweaks.

What safety certifications do Hawker chargers have?
All Hawker units meet UL 1564, CE, and IEC 60335-2-29 standards. They feature IP54-rated enclosures, reverse polarity protection, and GFCI (ground fault circuit interrupter) mechanisms.
Advanced models include isolated DC outputs and redundant temperature probes. For instance, if a coolant fan fails, the charger throttles current to 25% within 15 seconds. Moreover, arc flash protection auto-disconnects AC input if internal humidity exceeds 85%. Pro Tip: Test GFCI monthly by pressing the “trip” button—failure to cut power indicates worn relays needing replacement. 48V 450Ah/456Ah Forklift Lithium Battery

FAQs
No—their firmware lacks NiCd/NiMH profiles. Forced charging may overheat cells due to incorrect delta-V detection.
What’s the lifespan of a Hawker charger?
10–15 years with proper cooling. Dusty environments require quarterly air filter replacements to maintain thermal margins.
Do they support parallel charging?
Yes, but only with identical battery banks. Mixing chemistries or capacities bypasses current sharing protocols, risking imbalance.
