5S3P 18650 Battery Housing Storage Box & PCB BMS Set for Makita 18V Tools

Rebuild, repair, or assemble high-capacity power tool battery packs with this 5S3P 18650 Battery Housing Storage Box & PCB BMS Set. Engineered to accommodate fifteen 18650 lithium-ion cells in a 5S3P series/parallel layout, this heavy-duty battery casing delivers extended runtime and steady current delivery for demanding job site applications. Designed for seamless docking on Makita 18V LXT interface platforms, as well as compatible tools from Lomvum, Zhipu, Hongsong, and Jingmi, the kit includes a precision-molded Battery Management System (BMS) protection board. The integrated circuit actively safeguards connected cells against overcharging, deep discharge, over-current, short-circuiting, and thermal overload. Forged from high-impact, fire-retardant ABS polymer, it features internal cell matrix brackets, nickel connector plates, terminal blocks, and spring-loaded latches for a complete DIY battery rebuild.

Key Features

• 5S3P 15-Cell Capacity Matrix: Custom internal brackets hold fifteen 18650 cells to maximize battery pack capacity and operating runtime.

• Integrated PCB BMS Protection: Smart electronic circuit board guards against overcharge, deep discharge, short-circuiting, and overheating.

• Makita 18V LXT Interface Fitment: Precision-molded to dock smoothly onto Makita 18V tools and compatible Lomvum, Zhipu, and Hongsong equipment.

• High-Impact ABS Outer Shell: Flame-retardant casing shields internal battery cells from job site drops, dust, and heavy vibration.

• Complete Rebuild Component Kit: Includes outer plastic shells, internal matrix holders, nickel connector sheets, terminal block, and assembly screws.

• Cost-Effective Battery Salvage: Saves working 18650 cells by replacing cracked outer casings or failed circuit boards without buying expensive OEM units.

Why Choose Our 5S3P Battery Housing & BMS Kit

Discarding good lithium cells due to a damaged outer plastic shell or a burned controller board is wasteful and expensive. This 5S3P battery replacement kit combines 15-cell 18650 housing capacity, smart BMS electronic protection, high-impact ABS drop resistance, and exact Makita-style dock fitment—giving your cordless power tools, garage workshop gear, and DIY battery rebuilds an instant commercial-grade upgrade.
