The Umini 36V 2A Lithium Battery Charger is an ultra-compact, high-efficiency charging solution specifically designed for 10S Lithium-ion (Li-NCM) battery packs (nominal 36V, full charge 42V). Delivering a precise 42V output voltage and 2A constant current, it features a three-stage smart charging algorithm (CC/CV/trickle) to ensure complete and safe charging without overcharging. The ultra-small aluminum alloy housing (120Γ69Γ45mm) provides excellent heat dissipation and durability while taking minimal space. Ideal for e-bikes, electric scooters, portable power tools, and DIY 36V lithium battery projects.
β οΈ Connector compatibility check: This charger comes with a DC 2.1Γ5.5mm barrel jack (center positive). Verify that your battery pack or device has a compatible input before purchasing. Custom DC connectors are available upon request.
