Engineered for high-performance residential solar, the integration of EVE MB56 LiFePO4 cells and the JK PB2A16S30P (300A) Active Balance BMS sets a new benchmark for home energy storage. This system delivers an exceptional 8,000-cycle life and a continuous 300A charge/discharge capability, ensuring over 15 years of reliable service. Designed to handle heavy household peak loads with ease, it is a premier choice for DIY and professional off-grid power solutions in 2026.

New Arrival MB56 LF628K 628Ah 3.2V LiFePO4 Cell

Grade A,brand New Quality(The voltage, internal resistance, and capacity have been matched.)

Features

• Deep Cycle Battery: Discharge depth can reach 100%, storing more energy for the same weight and size, saving battery footprint.
• Long Cycle Life: After 8000 cycles, the actual remaining capacity is greater than 70%, with a lifespan of 15 years.

Some parameters

• Ultra-low Internal Resistance: 0.10±0.05mΩ. Effectively reduces battery loss and fully releases high current.
• 0.5P Charge/Discharge ratio: 314A continuous charge/discharge current, the battery can be fully charged in only 2-3 hours, with a continuous output power of 1kW.

Appearance Details

628Ah Cells with Pre-welded M8 Studs
Skip the complex setup. These cells come ready for your DIY battery projects, so no welding is needed.

They share the same height and thickness as the MB31, but with double the width for greater capacity in a familiar form factor.

The battery cell will be welded with a single M8 stud

Accessories

The MB56 cell comes with everything you need for assembly: flexible busbars, screws, and an epoxy plate. Build with confidence.

Flexible Busbars: Made of nickel-plated copper, offering excellent conductivity and oxidation resistance. With a thickness of 3mm, they can easily handle high currents of 300A without overheating. The flexible material protects the battery cells from damage to the terminals during use.

Package

Each package will contain two battery cells, which will be wrapped in high-rigidity custom foam and transported in a UN-compliant cardboard box.
