Safe use at home
Good safety performance, square aluminum shell structure, high precision explosion-proof valve design. 280Ah, long life, green environmental protection.
Our prismatic battery cells make ideal off-grid solar, campervan, marine and small off-road vehicle batteries. They are generally renowned for being the best DIY battery for energy storage applications due to their exceptional safety record, powerful storage and reliability.
Safe for commercial use
Strong iron phosphate lithium battery, cold and high temperature resistance, easy to solve the problem of electricity.
They have a lifespan of around 6000 cycles and charge at 0.5C (0.05C termination current up to 3.65V) with discharge 1C (down to 2.5V). These cells require connecting together with the included busbars and screws.
Wide application range
This connector is capable of handling the current, and is far safer, performing better than other studs or 3rd party connectors.Busbars (nickel plated copper) and screws (16 nuts and bolts) are included.
