I bought a polymer lithium battery (3.7V10A, 1C) on TB. Can I use TP4056 or IP5305, IP5306 module to charge and discharge it? [Copy link]

 

RT!

1 The battery is as follows:

The charging and discharging module bought on Taobao

1 TP4056

2 IP5305 or IP5306

Can the lithium-ion battery in this article be managed by the pmic management module listed in this article?

The charging and discharging module I bought explained it very clearly.

It is a ready-made charger. Just connect the battery and solder the wires and it will work.

The charging current of IP5306 is 2.1A. If it is a constant current in the early stage, will it explode the battery when encountering a 1000mAH 1C battery?

The battery you bought is

The capacity is relatively large.

The standard constant current charging stage of lithium battery is 0.1C, and the maximum charging current is 0.3C-0.4C. Too much current will damage the battery.

The battery picture is just an example, it is actually a 1500mAH, 1C polymer lithium battery

So the 1.2A charging current of tp4056 is not suitable? Not to mention the 2.1A charging current of IP5306

When buying a charging module, you need to ask the seller for the module description or the seller's marked precautions.

If you feel that the charging current is not appropriate, some can adjust the potentiometer to select the required charging current.

Since the OP bought it on TB, I'll just give you an example.

Enter TP4056 in TB and find a random module.

I want to know how the current flagship mobile phones are charged with super fast charging.

for example

1 Huawei's scp 40w fast charge can achieve 9V2A ~ 10V4A;

2 OPPO's 65W Super Flash Charge 5V5A~ 9.2V6.3A

They are all polymer lithium batteries, aren't they all 3.7V?

Ordinary batteries will limit the charging current. Fast charging, especially low-voltage and high-current fast charging, should be a special battery.

To use a popular analogy, the mouth of an ordinary bottle of the same size is so small that it cannot be filled too quickly. A specially made wide-mouth bottle can be filled faster with a larger flow of water.

I read an article before, and then I understood it this way. I don't know if it is right, so I'd like to share it for discussion and hope to get confirmation.

Battery capacity and fast charging are double-edged swords

I vaguely remember connecting two batteries in parallel to increase the charging current

Connecting two batteries in parallel increases the charging current? How much? Does it make sense?

Connecting in parallel increases capacity while keeping the voltage constant. Connecting in series increases voltage while keeping the capacity constant.

The smaller the charging current, the better. It doesn't matter if you have time to wait. 0.1C takes 10 hours. Who can afford to wait for practical applications?
