High-efficiency waterproof LiFePO4 and lithium-ion chargers engineered by Shenzhen Eltrum Electronic Co., Ltd. for marine vessels, electric vehicles, utility fleets, and industrial equipment.
Engineered by Shenzhen Eltrum Electronic Co., Ltd., our AC-DC battery charger lineup delivers regulated multi-stage charging optimized for Lithium Iron Phosphate (LiFePO4) and ternary lithium battery packs. Built with die-cast aluminum heat sinks, full internal resin encapsulation (IP65/IP67 rated), and high-efficiency resonant topology, our units operate continuously under harsh moisture, vibration, and thermal environments.
Multi-Stage CC/CV Curve
Pre-charge, constant current bulk charge, and constant voltage absorption ensure fast recharging while protecting battery cell longevity.
Universal AC Range
Wide input voltage window (90V–265V AC, 50/60Hz) accommodates regional mains power across Europe, the Americas, Asia, and Australasia.
Full Protection Suite
Equipped with integrated short-circuit, over-voltage, over-temperature, reverse polarity, and auto shut-off protection.
Standardized surface mount and automated insertion lines ensure accurate component placement, uniform thermal dissipation, and consistent solder quality across all AC-DC power supplies and charger assemblies.
100% Full-Load Burn-In & Testing
Every battery charger unit undergoes rigorous burn-in cycles under maximum load, dielectric withstand tests, and precise CC/CV calibration before packaging to eliminate infant mortality risks.
Frequently Asked Questions for B2B Procurement
Can these chargers be left connected to LiFePO4 batteries permanently?
Yes. Shenzhen Eltrum Electronic Co., Ltd. engineers our chargers with automatic cut-off and float maintenance logic designed specifically for LiFePO4 chemistries. When the battery reaches full charge capacity (e.g., 14.6V on a 12V 4S bank), current drops close to zero, preventing overcharging without damaging cell separators.
What customizations are available for OEM buyers?
We provide custom DC output plugs (Anderson, XLR, GX16, terminal rings), custom AC power cables (US, EU, UK, AU), specific voltage calibration points (such as 14.4V vs 14.6V or 54.6V vs 58.4V), private labeling, and custom aluminum enclosure colors for bulk purchase orders.
What certifications are supplied with volume shipments?
Our manufacturing lines operate strictly under the ISO 9001 quality management framework. Products comply with CE EMC, LVD standards, and RoHS environmental requirements. Official test reports and documentation are available upon request via [email protected].
