Ryobi 18V ONE+ Compatible Battery Build Kit – 10-Cell 18650

Build a complete Ryobi 18V ONE+ compatible battery pack using ten 18650 lithium-ion cells.

This complete DIY battery build kit includes a new battery housing and the matched internal components needed to assemble a compatible Ryobi 18V battery pack. Battery cells are not included.

This is a battery build kit, not an OEM-style rebuild kit. The housing, circuit board, cell holders, contacts, and other internal components are designed to work together as one complete set. The internal parts may differ in size, shape, and layout from the components found inside an original Ryobi battery and are not intended to be installed individually into an original battery housing.

Assembly Requirements

This product is intended for experienced users who understand lithium-ion battery construction, cell testing, insulation, polarity, series and parallel connections, and spot welding.

The buyer is responsible for selecting suitable high-drain 18650 cells with the correct voltage, capacity, discharge rating, and specifications for the intended application.

Use only properly tested and closely matched cells. Do not mix cells of different brands, models, capacities, ages, voltage levels, or conditions.

Important Safety Information

Improper lithium-ion battery assembly can cause fire, personal injury, equipment damage, or property damage. Proper battery-building knowledge, tools, insulation, testing equipment, and safety procedures are required.

Always verify polarity, wiring, insulation, and pack voltage before connecting the completed battery to a tool or charger.
