TOPWELL-lithium polymer battery and 18650 lithium battery products video

How to choose an outdoor power supply? While we consider the practicality, we must also consider the safety of use. The product must choose a big brand. Secondly, after getting the product, we must check whether it supports earthquake resistance and drop resistance, and we must also look at the heat dissipation, just like this one. TOPWELL 500W portable outdoor power supply has done a good job in this aspect. The temperature control of the whole power supply is very good, and the AC output of 220V is also very stable, and it is a pure sine wave, so there is no need to worry about damaging the equipment. The built-in battery is a lithium iron phosphate battery, which uses an automotive-grade power battery with less heat generation and a long life. The advantages of this type of battery are anti-overheating, overcurrent, overvoltage, short circuit, and overload. On the whole, if our needs are for simple short-distance travel or business trips, without large electrical equipment, such a light and compact outdoor power supply is actually the most suitable.

Lithium polymer batteries are the latest innovations in battery technology. Compared to traditional rechargeable batteries, lithium polymer batteries offer several advantages. They have a high energy density, longer life expectancy, are lightweight and can be molded into any shape or size. This has made them popular in a broad range of applications, including mobile devices, electric vehicles, electric bikes, drones, and even full-fledged power grids. In this blog post, we explore how lithium polymer batteries are revolutionizing the power industry.

Will low temperature affect lithium battery life? What are the requirements of lithium battery for battery management system?

Low temperature will affect the life of lithium battery. The electrode materials of lithium-ion batteries have reduced activity at low temperatures, increased resistance, reduced electrochemical reaction rates, reduced battery capacity, and reduced charge and discharge efficiency, thereby affecting the life of lithium batteries.

Today, Yichun Topwell Power Co., Ltd will show you how to calculate the data of some common solar power generation systems, and use this to choose suitable accessories.

First of all, we need to understand some basic circuit knowledge, such as Ohm's law (that is, voltage = current * resistance), and the calculation formula about power:
