Key Features
- 2S Li-Ion Chemistry — This battery utilises lithium-ion technology across two cells, delivering higher energy density and lighter weight than traditional NiMH batteries, which translates to better performance and faster acceleration in your Jet Jam pool racer.
- 7.4V Nominal Voltage — The 7.4V output is the standard voltage for 2S Li-Ion packs and is perfectly calibrated for the electronic speed control systems and motors found in Pro Boat's Jet Jam range, ensuring safe operation and optimal power delivery without risk of over-voltage damage.
- 1500 mAh Capacity — With 1500 milliamp-hours of stored energy, this battery provides a balanced run time for pool racing sessions, allowing you to enjoy extended playtime without the battery becoming too heavy or reducing your boat's performance through increased weight.
- Jet Jam Pool Racer Compatibility — This battery is purpose-built for the Jet Jam 12-inch pool racer and related models in the range, ensuring perfect fit, weight distribution and electronic compatibility with your watercraft's power system.

Technical Performance
The DYN 7.4V 1500 mAh 2S Li-Ion battery is engineered to deliver dependable performance in the demanding environment of RC pool racing. The 2S configuration (two cells in series) produces a nominal voltage of 7.4 volts, which is the industry standard for small-scale electric RC boats and watercraft. At 1500 mAh capacity, this battery pack stores sufficient energy to power your Jet Jam pool racer for an extended session, with run times typically ranging from 10 to 20 minutes depending on driving style and throttle usage. The lithium-ion chemistry ensures minimal voltage sag under load, meaning acceleration remains crisp and responsive even as the battery discharges. Unlike older nickel-metal hydride (NiMH) batteries, Li-Ion packs maintain a flatter discharge curve, so your boat won't gradually slow down as the battery drains. The lightweight construction of modern Li-Ion cells helps keep your pool racer agile and responsive in the water, critical for competitive pool racing where manoeuvrability and top speed are paramount. Charging is straightforward with compatible Dynamite chargers (such as the USB Charger model PRB18019 available separately), and proper maintenance — including regular inspections and safe storage practices — will extend the lifespan of your battery investment significantly.

Frequently Asked Questions
- Is this battery suitable for beginners using RC boats in the UK? — Yes, absolutely. The 7.4V 2S Li-Ion configuration is the standard power source for ready-to-run RC boats like the Jet Jam pool racer, making it ideal for newcomers to the hobby. The battery is easy to charge, safe to use with proper care, and provides consistent performance. Beginners simply need to follow basic charging and storage guidelines, and they'll have reliable power for their watercraft.
- What charger do I need for this 7.4V 2S battery? — You'll need a charger designed for 2S Li-Ion packs, such as the Pro Boat USB Charger (model PRB18019) which is available separately. This charger is specifically designed for Jet Jam pool racers and plugs into standard UK power outlets via USB. Always ensure you're using a charger rated for Li-Ion batteries, as charging the wrong battery type or voltage can be unsafe.
- How long does this battery last on a single charge? — With the 1500 mAh capacity, typical run times range from 10 to 20 minutes, depending on how aggressively you drive, throttle usage, and water conditions. More conservative driving extends run time, whilst continuous high-throttle racing will reduce it. Most RC boat enthusiasts purchase multiple batteries so they can rotate them and enjoy extended play sessions.
- What makes Li-Ion better than older NiMH batteries for RC boats? — Lithium-ion technology offers several advantages: higher energy density (more power per gram of weight), lighter construction (keeping your boat faster and more responsive), a flatter discharge curve (your boat won't slow down as the battery drains), minimal memory effect (you can charge any time without degrading capacity), and longer overall lifespan. For pool racing where performance and weight matter, Li-Ion is the modern standard.
- Is this battery compatible with all Jet Jam models? — This battery is designed for the Pro Boat Jet Jam 12-inch pool racer and related models in that range. To ensure compatibility, check your product manual for the V2-specific part number (O-DYNB0110) or contact our knowledgeable team at RC Model Shop. Many items are V2-specific, so matching the code ensures the perfect fit.
- How should I maintain and store this battery? — After each run, rinse your boat with fresh water and dry thoroughly. Store the battery in a cool, dry place away from extreme temperatures. Check the battery and charging connectors regularly for any signs of damage. Periodically charge the battery even if not in use, as Li-Ion cells can slowly self-discharge. Avoid deep discharges and overcharging, which shorten battery life. Many enthusiasts use a quality battery storage case for protection.
