12v Lithium-ion Battery Pack Selection Skills

1. Selection skills of 12v lithium-ion battery packs: check appearance and packaging, compare components

First, it can identify the packaging and appearance of 12v lithium-ion battery pack products. Although the general product looks deceiving, it can also be filtered out from the appearance of some defective products. The composition of lithium-ion batteries is directly proportional to the capacity. If it is a polymer lithium-ion battery, the difference in composition is too large, and the capacity will inevitably be insufficient, but some batteries themselves have different capacities. In addition, the weight of the battery can be seen from the packaging, if heavy people prefer high-quality lithium-ion batteries.

2. Selection skills of 12v lithium-ion battery pack: check the appearance and capacity

Look at the appearance refers to the appearance, process, size and technology of lithium-ion batteries. Check whether the seam width of the shell is wide, whether there are burrs, whether there is oil stain, it feels good, and the advanced technology feels very comfortable. After polishing, the rubber varnish material feels good, and at the same time, the insulation performance is also strong.

See if you can figure out the capacity of a Li-ion battery without knowing its capacity, most likely by using the leftover battery or reassembling the leftover battery. There are many low-cost 12v lithium-ion battery packs on the market, whether you use recycled batteries or removed batteries, the price is of course cheap, but the life is short, the quality is unstable, and careless use may damage the device and cause an explosion.

3. Selection skills of 12v lithium-ion battery pack: check the lithium battery circuit board and brand

The maintenance circuit of the 12v lithium-ion battery pack characteristics solves the problem that the lithium-ion battery must be added to the maintenance board. In order to prevent the lithium-ion battery from overcharging, over-discharging and short circuit, if the lithium-ion battery does not have the maintenance board, there will be risks of deformation, leakage, and explosion. Faced with fierce price competition, battery packaging companies are looking for cheaper ways to maintain circuits, potentially phasing out the device entirely and flooding the market with potentially explosive lithium-ion batteries. Of course, in practice, consumers cannot distinguish and maintain circuit boards from the appearance, so it is best to choose reputable merchants to buy.

There are many brands of 12v lithium-ion battery packs, and it is difficult to tell the quality from the appearance. In this case, everyone should do a little more homework before making a choice, and check the manufacturer's information online. Generally speaking, professional manufacturers are more reliable than small workshops, and manufacturers with long working hours are more reliable than those who have just entered this field.
