Why, and for who, is this B4850 battery a good choice?

You should opt for this battery if you are a low power consumption household that would like to store excess solar energy or energy from the grid for power outages. The B4850 2.4kWh is a good choice for many reasons:

  • It is affordable: This battery is not only of high quality, and robust, but is one of the most (if the most) affordable Lithium-ion batteries on the market today.
  • It offers a long life: This battery is rated to do 6000 cycles at 80% depth of discharge (DoD), with a 20 year lifespan of which 10 years is guaranteed.
  • It is modular in design: The battery is universally compatible with most inverters such as Axpert, Goodwe, Growatt, Sofar, Sunsynk Deye, and is scalable. You can stack up to 16x of these batteries in parallel for in-grid or off-grid usage.
  • It has a BMS: It has an intelligent Battery Management System (BMS) which will protect against damage from over- and under-charging; and will manage the modules and battery packs effectively. This enhances the cycle life of the battery.
  • It is safe: The LiFePO4 batteries are the safest type of Lithium batteries as they will not overheat, and even if punctured they will not catch on fire. The cathode material in LiFePO4 batteries is not hazardous, and so poses no negative health hazards or environmental hazards.
  • It offers a 10 year warranty: It comes with a 10 year warranty which already beats most other lithium-ion batteries available, which speaks volumes to its quality and trustworthiness.


What can the Dyness 2.4kWh battery power?

While the battery holds 2.4kWh of energy, no battery should ever be fully discharged. The Dyness B4850 2.4kWh battery can comfortably be discharged to a depth (DoD) of 80% and deliver 6000 cycles from 100% to 20%. This means the battery holds approximately 1.92kWh of usable energy. This means, for example, that you can power electrical appliances that consume 480 Watts for 4 hours, or 768 Watts for 2.5 hours, or 960 Watts for 2 hours.
