Introduction
Under the brand Dineng Battery we offer a variety of battery packs LiFePO4 (Lithium-Iron-Phosphate) or Li-ion battery on various sizes and technical specifications.
Why LiFePO4?
LiFePO4 batteries have in terms of cycle stability (lifetime), dimensions, energy density and corresponding weight distinct advantages over the widely used lead acid batteries.
Compared to conventional lead-acid batteries LiFePO4 can be almost completely discharged without suffering a great voltage drop. While a lead-acid battery can deliver abouthalf of its rated capacity, the rated capacity of LiFePO4 batteries is nearly the real available capacity.
Furthermore, the LiFePO4 battery characterized by a comparable long life. The LiFePO4 battery cells have to replace a nominal voltage of 3.2V-3.3V and can therefore excellent in the formats 6V (6.4V), 12V(12.8V), 24V (25,6V) lead-acid batteries.
Applications
LiFePO4 batteries can be applied wherever previously sealed lead acid batteries were used. Whether small and large solar systems, caravans, motors, UPS systems (uninterruptible power supply), or medical devices, these batteries can easily replace the conventional lead-acid batteries. Even small devices such as echo sounder, measuring instruments, toys can be operated longer with such batteries.
Are LiFePO4 batteries expensive?
Often the purchase prices of LiFePO4 could be seen as a disadvantage compared to lead batteries. This is only partly true, because in many applications where the lead-acid batteries exhausted quickly, the LiFePO4 battery is even more cost effective. The long lifespan of well over 2,000 charge and discharge cycles sets the price per Wh far below the price per Wh in lead batteries charge.
BMS – Can do without it!
The BMS (Battery Management System) is the most important component in a LiFePO4 battery, because not only it protects against overcharging and deep discharge, but it also borders the removable current (expressed in amperes). We speak of protection against over-discharge.
Another important feature is the so-called balancing of the battery cells. In order to keep the battery‘s durability and performance equal, all built-in battery-cells inside the battery-pack must remain as homogeneous as possible. The battery cells in must maintain similar voltage level at all times.
