Product highlights

1. Modular design, allowing for free capacity expansion

• You can first purchase a single module (48V30AH or 48V50AH) to test the motor performance and accurately calculate the required capacity.

• By paralleling up to 8 modules through the QuadCell docking station, seamless upgrades from small capacity to large capacity can be easily achieved.

2. High-safety lithium iron phosphate battery

• The battery cell material is stable, resistant to high temperatures and impacts, eliminating the risk of fire and explosion.

• Supports 3C continuous discharge. The peak output of a single module EB-4850 is 150A, meeting the requirements of high-power motors.

3. Intelligent BMS+LED monitoring screen

• It is equipped with an intelligent BMS system that monitors overcharge, overdischarge, short circuit and temperature in real time to ensure battery safety.

• The LED screen clearly displays voltage, current and remaining battery power, making the usage status clear at a glance.

4. Versatile for both Marine and outdoor use

• The stainless steel casing is waterproof and corrosion-resistant, suitable for humid Marine environments.

• The lightweight design makes it convenient to carry and use in various scenarios such as docks, camping, and RVS.

Application scenarios

• Electric boats: Replace fuel power, quiet and environmentally friendly, with freely adjustable range.

• Outdoor energy storage: Camping and RV power supply, supporting long-term operation of high-power electrical appliances.

• Emergency backup: Reliable power reserve for docks and off-grid residences.

Purchase Instructions
