Application

application

LiFePO4 battery Advantage

BMS system inside

High energy density - potential for higher capacities.

Does not need prolonged priming when new. One regular charge is all that's needed.

Relatively low self-discharge - self-discharge is less than half that of nickel-based batteries.

Low Maintenance - no periodic discharge is needed; there is no memory.

Specialty cells can provide very high current to applications such as power tools.

Sea Transport considerations

1. The battery must pass the UN38.3 test requirements and the 1.2-meter drop packaging test.

2. The outer packaging must be affixed with a Category 9 dangerous goods label, marked with the UN number.

3. Its design can ensure the prevention of bursting under normal transportation conditions, and is equipped with effective measures to prevent external short circuits.

4. Strong outer packaging, the battery should be protected to prevent short circuit, and in the same packaging, it should be prevented from contact with conductive materials that can cause short circuit.

5. Additional requirements for battery installation and transportation in equipment:The equipment should be fixed to prevent it from moving in the packaging, and the packaging method should prevent accidental activation during transportation. The outer packaging should be waterproof, or by using an inner lining (such as a plastic bag) to achieve waterproofness, unless the structural features of the device itself are already waterproof.

6. ​​Lithium batteries should be loaded on pallets to avoid strong vibration during handling. All vertical and horizontal sides of the pallet should be protected by corner guards.

How to choose lithium battery

1. Check the appearance and packaging

First of all, lithium battery products can be judged from the packaging and appearance. Although the appearance of general products is deceptive, some inferior products can also be screened out from the appearance.

2. Compare weight

The weight of a lithium battery is directly proportional to the capacity. If it is a polymer lithium battery, if the weight difference is too large, the capacity will definitely be insufficient, but there are differences in the size of the capacity of some batteries. In addition, you can also feel the weight of the battery from the outer packaging. If the weight is heavy, it is biased towards high-quality lithium batteries.

3. Test internal resistance and maximum current

In fact, the fastest inspection method to judge the performance of lithium batteries is to test the internal resistance and the maximum discharge current. A good quality lithium battery has very low internal resistance and a large maximum discharge current. Use a multimeter with a 20A range to directly short the two electrodes of the lithium battery. The current should generally be about 10A, or even higher, and it can be maintained for a period of time. A relatively stable battery is a good battery.

4. Test live work

During the live working process of the lithium battery, if the two poles of the battery are not hot after continuous discharge for about 10 minutes, it proves that the battery protection board system is perfect. Generally, the quality of the lithium battery with a high-quality protection board is better than that of the ordinary lithium battery.

5. Look at the battery cell

Most of the cells used in lithium batteries are soft pack cells and 18650 cells, which are also common materials for lithium battery pack cells. First check whether the batteries are brand new, because there are some bad small workshops on the market that use second-hand batteries to make lithium batteries. Soft-packed lithium batteries, also known as polymer batteries, are batteries with a gel-like soft-packed electrolyte, which can be made into various shapes. The battery is safe and does not explode.
