Want to extend your e-bike’s range or power? This dual battery parallel adapter lets you connect two 20V–72V battery packs to your electric bike controller at the same time. It’s rated for 40A and made from lightweight aluminum alloy, so it’s durable and helps with heat dissipation. The adapter uses XT60 connectors—the male end plugs into two batteries, and the female end connects to your controller. It increases overall current, battery capacity, and discharge power, giving you longer rides and more consistent performance. Important: Both batteries should have similar voltage (don’t mix very different voltages), and make sure your controller supports the input range. Perfect for DIY e-bike builders, upgraders, or anyone who needs extra juice for long commutes or hilly terrain. Just one adapter included—get ready to ride farther!
