Handheld measuring devices and portable inspection hardware require greater capacity than standard cells can deliver within the same enclosure. MAGNATE New Energy develops custom Li‑ion battery packs balancing high energy density and rechargeable performance for portable industrial instruments. Our Li‑ion battery fits applications needing compact size paired with higher capacity, such as handheld measuring devices, portable inspection hardware and smart field equipment. We combine matched cells with protection circuits and industry-standard connectors to build ready-to-install packs tailored to your power draw and enclosure limits. Each pack passes testing for charge stability, short-circuit protection and consistent capacity before shipment. We adjust pack dimensions, wiring and terminations around existing housings to cut your product redesign workload. Share your mechanical drawing and power consumption profile, and our engineers will propose a practical battery layout for your device.
