Do you have Makita batteries and chargers? Do you want to use cool Ryobi tools? Don't want to spend $25 on a Badaptor or Surebonder? Then this is for you! This is a proper Makita battery adapter for Ryobi tools. It can be installed/used in three ways: 1. Removable, using side latches, which is useful if you own Ryobi batteries and chargers. 2. Semi-permanent, using screws to fix the adapter to the tool, which is useful if you don't own Ryobi batteries and chargers. 3. Permanent, using screws and soldering contacts directly, which is useful if you want a quick way to convert Ryobi tools to Makita. This adapter uses genuine Makita terminals pad (such as 643852 or 643838).
