24V Dyness DL2.5 100Ah 2.56kWh Lithium Battery
Product Description:
The Dyness DL2.5 24V 100Ah Lithium Battery is a compact and scalable energy storage solution designed for residential, business, on-grid and off-grid solar applications. With 2.56kWh of nominal energy, dependable LiFePO4 chemistry and a 95% depth of discharge, it provides an efficient alternative to traditional lead-acid batteries.
The DL2.5 is particularly suitable for properties in areas with an unreliable electricity supply or limited grid access. Its modular design allows the storage capacity to be expanded from 2.56kWh to a maximum of 40.96kWh by connecting up to 16 compatible batteries in parallel.
Compared with conventional lead-acid storage, the Dyness DL2.5 offers higher energy density, a longer service life, faster charging and reduced maintenance requirements. Lithium Iron Phosphate technology also provides improved thermal and chemical stability, helping to reduce the risks associated with overheating.
Its slim, wall-mounted construction makes it a practical choice where installation space is limited. The battery includes power cables, a communication cable and a wall-mounting shelf for easier system integration.

Safe Lithium Iron Phosphate Technology:
The Dyness DL2.5 uses Lithium Iron Phosphate battery cells, commonly referred to as LiFePO4 or LFP. This battery chemistry is known for its thermal stability, long operating life and dependable performance in solar energy storage applications.
The battery provides a longer service life and higher usable capacity than many conventional lead-acid batteries, while requiring less routine maintenance.
Scalable Battery Storage:
One Dyness DL2.5 battery provides 2.56kWh of nominal storage capacity. Up to 16 compatible units can be connected in parallel, allowing the system to be expanded to approximately 40.96kWh.
This flexibility allows users to begin with a smaller battery system and increase the storage capacity as their energy requirements grow.
Suitable Applications:
Residential solar backup systems
Small business backup power
On-grid solar energy storage
Off-grid solar systems
Areas with limited or unreliable grid electricity
Essential appliance backup
Modular solar battery installations
Replacement for compatible lead-acid battery banks
