2023 Seaborg G400J/400J LeoBrits S500JP and others also OK Confirmed using actual electric reels Please note that batteries and reels are not included with the product You can use your Makita batteries to power Daiwa and Shimano electric reels. Both 14.4V and 18V batteries can be used. Compatible batteries are also fine! 14.4V light batteries are not supported. The first image is the item for sale (batteries and reels are not included). You don't have to buy expensive manufacturer-original batteries; you can effectively use the batteries from your power tools that you use for work. It's set to 15.5V, so the high voltage provides powerful winding that you'll get hooked on. You won't be able to go back to unstable boat power supplies or low-voltage car batteries. The internal circuit board has a proven track record with over 300 units. I was also involved in its development. Word of mouth has spread on a certain boat in Aichi that I often fish on, and many people have one. Be careful of inferior products; they often break down quickly or overheat. Some products are clearly not providing enough current. Some products are sold that don't allow the reel to perform to its full potential. Like power tools, it's the type that securely locks the battery, so it won't come loose from vibration, providing stress-free and reliable use. The cable is 2.4m long, and the connector is a 2-pin type.
