DKLR48105D-RACK 48V105AH lithium battery Lifepo4
Basic structure, advantages and disadvantages of cell
A typical prismatic cell, important components include: top cover, shell, positive plate, negative plate, lamination or winding of diaphragm, insulating parts, safety components, etc., and two are safety structures, NSD needle safety device; OSD overcharge protection device.
The needle-punching safety protection device is to add a metal layer, such as copper sheet, on the outermost side of the coil core of the prismatic core. When the acupuncture occurs, the local large current at the acupuncture position rapidly reduces the current per unit area through a large area of copper sheet, which can prevent the local overheating at the acupuncture position and slow down the occurrence of thermal runaway of the battery.
The overcharge safety protection device can be seen on many lithium batteries at present. It is generally a metal sheet, which can be used with a fuse. The fuse can be designed on the positive current collector. During overcharge, the pressure inside the prismatic cell causes the overcharge protection device to trigger an internal short circuit, which causes an instantaneous large current, thus making the fuse fuse fuse and cutting off the internal current circuit of the battery.
Product Description
● Long Cycle Life: 10 times longer cycle life time than lead acid battery.
● Higher Energy density: the energy density of lithium battery pack is 110wh-150wh/kg, and the lead acid is 40wh-70wh/kg, so the weight of lithium battery is only 1/2-1/3 of lead acid battery if the same energy.
● Higher Power Rate: 0.5c-1c continues discharge rate and 2c-5c peak discharge rate, give much more powerful output current.
● Wider Temperature Range: -20℃~60℃
● Superior Safety: Use more safer lifepo4 cells, and higher quality BMS, make full protection of the battery pack.

The reasons for the safety of lithium iron phosphate battery are:
The PO bond in lithium iron phosphate crystal is stable and difficult to decompose, and it will not collapse and heat or form strong oxidizing substances at high temperature or overcharge.
The advantages of lithium iron phosphate battery are:
1. Long service life of lithium iron phosphate battery;
2. Safe use;
3. Fast charging;
4. High temperature resistance of lithium iron phosphate battery;
5. Lithium iron phosphate battery has large capacity;
6. Lithium iron phosphate battery has no memory effect;
7. Lithium iron phosphate battery is green.
The disadvantages of lithium iron phosphate battery are:
1. The positive pole of lithium iron phosphate battery has low tamping density;
2. Poor conductivity;
3. Low temperature performance of lithium iron phosphate battery is poor.
