eFoil riders, schools, rental fleets, and island resorts need battery packs that lift instantly, survive saltwater, and minimize downtime. Junda Battery designs and builds marine-grade lithium packs specifically for electric hydrofoil boards. As a battery pack manufacturer, we convert your performance targets into safe, repeatable production—IP68 sealing with potting, corrosion-resistant hardware, and a smart BMS with BT/CAN, logging, anti-spark, and multi-NTC protection.
Platforms cover 43.2V / 48V / 51.8V / 100.8V up to 54Ah, with UN38.3 shipping compliance and local warehousing in the United States, Canada, and the European Union. Popular builds include 43.2V 24/27/48/54Ah, 48V 27/54Ah, 51.8V 54Ah, and 100.8V 54Ah. We support OEM/ODM for global brands and battery pack suppliers, enabling faster development cycles and reliable field performance.
When global brands and OEM partners search for eFoil battery solutions, they choose us for one reason—performance with trust. With over 500+ successful OEM/ODM projects, a 98% on-time delivery rate, and full compliance with CE, UL, and UN38.3 certifications, we deliver more than batteries—we deliver confidence. Whether you are sourcing a Lift eFoil battery replacement or a Takuma eFoil battery pack, our factory ensures consistent quality and long-term reliability.
Junda offers a range of reliable, waterproof, and high-discharge battery packs built with premium 21700 cells. Designed to meet the unique demands of efoils and USVs, our off-the-shelf solutions combine robust energy output with marine-grade durability.
We typically provide custom eFoil battery packs in 48V, 52V, or 60V configurations, with capacities ranging from 20Ah to 60Ah or more. Each pack is tailored based on your runtime expectations, motor specifications, and waterproofing needs.
Yes. At Junda Battery, we design marine-grade enclosures with IP67 or IP68 protection levels. These casings prevent water ingress during eFoil operation and are pressure-tested for saltwater environments.
We use premium-grade cylindrical cells (typically 18650 or 21700) from brands like Samsung, LG, or Molicel. These are selected based on energy density, discharge rate, and thermal stability.
All eFoil batteries are equipped with a smart BMS that controls cell balancing, over-current/over-voltage protection, and temperature monitoring. Additional thermal shielding and waterproof venting are added based on the use case.
Yes. Our BMS supports communication protocols such as CAN Bus or RS485. These allow real-time battery diagnostics and integration with eFoil control systems or external displays.
Absolutely. We specialize in custom-shaped lithium battery packs. You can share your 3D design or space constraints, and our team will engineer a battery pack that matches your enclosure while maximizing capacity and thermal performance.
