Tips for selecting lithium iron phosphate batteries.

There are various types of lithium iron phosphate batteries on the market, and the quality is also uneven. If you don't choose a good lithium iron phosphate battery and buy a low-quality lithium iron phosphate battery, it will also be harmful to later use. If you want to choose a high-quality battery, see how the editor teaches you to choose.

Firstly, lithium iron phosphate battery products can be judged from their packaging and appearance. Although ordinary products may appear deceptive in appearance, they can also filter out some inferior products based on their appearance.

The weight and capacity of lithium iron phosphate batteries are directly proportional. If the weight difference is too large for polymer lithium iron phosphate batteries, the capacity will definitely be insufficient, but some batteries have differences in their own capacity. In addition, the weight of the battery can also be perceived from the outer packaging to see if it is relatively heavy. If it is heavy, it tends to be high-quality lithium iron phosphate batteries.

Test internal resistance and high current

In fact, the fast testing method for judging the performance of lithium iron phosphate batteries is to test the internal resistance and large discharge current. A high-quality lithium iron phosphate battery has a very small internal resistance and a high discharge current. Using a 20A range multimeter and directly short circuiting the two electrodes of a lithium iron phosphate battery, the current should generally be around 10A or even higher, and can be maintained for a period of time. A relatively stable battery is a good one.

During the charged operation of a lithium iron phosphate battery, if the two poles of the battery do not heat up after continuous discharge for about 10 minutes, it indicates that the battery protection board system is complete. Generally, lithium iron phosphate batteries with high-quality protection boards have better quality than ordinary lithium iron phosphate batteries.

Most of the cells used in lithium iron phosphate batteries are soft pack cells and 18650 cells, which are also common materials for lithium iron phosphate battery pack cells. Firstly, check if the battery cells are brand new, as there are some unscrupulous small workshops in the market that use second-hand battery cells to make lithium iron phosphate batteries. Soft pack lithium cells, also known as polymer cells, are a type of battery with a gel like electrolyte that can be made into various shapes. The battery has high safety and will not explode.
