BAYWATT 48V 60Ah Portable Battery (2.88 kWh) — Standard & Solar MPPT Versions

Energy: 48V 60 Ah = 2880 Wh (2.88 kWh)

Discharge: 2C continuous — supports high-power electric outboards and trolling motors with minimal voltage sag.

Weight: ~20 kg with reinforced ergonomic handle (similar to a 20L fuel can), balanced for safe carrying and stable onboard storage.

Available Versions

• B8860 – Standard Version: 48 V portable propulsion battery with dedicated high-current charge port and Anderson connectors for motor output.
• B8860-MS – Solar MPPT Version: same 48V / 60Ah pack, upgraded with integrated MPPT solar charge controller, Bluetooth monitoring, 120A BMS, and M8 eye-ring terminals instead of Anderson for improved waterproofing and direct photovoltaic connection.

What it powers

• 48V drive output: Capable of running any 48V outboard motor or trolling motor available on the market. Perfect match for inflatable dinghies, small RIBs, river boats, and fishing boats that need reliable propulsion and instant torque.
• Versatile voltage options: By adding a quality step-down DC converter, this battery can also provide stable, regulated power for 12V and 24V motors, as well as auxiliary on-board systems.
• Accessory outputs (common to both versions):
  • 12V DC socket (110 W max): to run a fish finder, GPS chartplotter, or a cooling box while on the water.
  • USB 3.0 + USB-C fast charge: to recharge smartphones, tablets, action cameras, or navigation tablets.
• Charging input (B8860 – Standard): dedicated charge port, compatible with fast 48V chargers.
• Solar-ready input (B8860-MS – Solar MPPT): integrated MPPT controller for direct PV connection via M8 eye-ring terminals.
• Extended autonomy: up to 3 batteries can be paralleled (same model, same state of charge) for longer trips or heavier loads.

Foldable Solar Panel Kit (for B8860-MS)

The B8860-MS solar version is designed to work with a 300W foldable solar panel set on a 48 V system.

• Plug-and-play: the panel connects directly to the solar input of the B8860-MS via the integrated MPPT controller.
• Use case: recharge the battery at anchor, on a mooring, or during slow cruising to extend range and reduce shore-power dependency.

Smart power management & safety

• LCD display: shows real remaining percentage (% SOC) for precise range planning.
• Thermal circuit breaker: overload protection with quick manual reset.
• Advanced BMS: active cell balancing + user-adjustable max output cap to smooth peaks (useful in heavy current or when you want to limit power to save energy on lakes, rivers or in ocean swell).
• Système de gestion de la batterie avec protection contre les surcharges, les courts-circuits, la décharge profonde, la surchauffe et l’immersion (BMS function). (Boîtier étanche aux éclaboussures : éviter toute immersion.)
• Enclosure: splash-proof box; designed for decks and cockpits, not submersion.
• Bluetooth monitoring (B8860-MS): wireless monitoring of voltage, current, power and state-of-charge via compatible app.
• Integrated MPPT (B8860-MS): optimises solar harvest from the 300 W foldable panel set for faster and safer charging.
