Imagine a battery so compact it tucks neatly under your kayak seat or secures effortlessly to the back of your paddleboard. Lightweight, yet powerful, the PP-378 is built to endure the harshest marine conditions. Fully waterproof, saltwater-resistant, buoyant, and fast-charging, this rugged powerhouse keeps you on the water for over 75 minutes at full power or 10 hours at trolling speeds -so you can explore, fish, and adventure without limits! No need to imagine, at just over 7 lbs (3.17 kg), the PP-378 provides finely tuned power to your Bixpy Motors for efficient, long-lasting performance. The PP-378 also features a communication module for wireless control of your battery, providing your motor with 12 forward speeds and three reverse speeds via a wearable, waterproof, and buoyant Remote Control. Charge your PP-378 with the included wall charger in about 5 hours or with the SUN80 Solar Panel in 6 to 10 hours of sunlight. Version 4 of the PP-378 also offers Warp Speed* and Error Clear** from your remote in addition to other safety features for the battery and motors.
