Steps to Custom Your 48V Lithium ion Battery 

1 Lithium Battery Cell Selection

There are many different types of lithium batteries in the market. No one type works for all applications. For example, robotics need a high discharging output; power tools need high discharge C rate;

18650 Battery Cell

Energy storage systems need high power density; Car Jump Starter batteries need to be operable even in freezing temperatures, and batteries with daily charging/discharging usage may need a long cycle life.

That’s why you should tell us the application of your lithium battery pack.

We have been in the lithium battery application industry for more than 10 years. We are familiar with the battery supplier chain and quality is our life. We will offer you the most suitable lithium battery cells based on performance, price, and reliability.

2 Choose Battery Management System

Battery Management System (usually short for BMS), which is an electronic regulator that mainly designed to monitor and control the charging and discharging voltage and current of lithium battery cells or other rechargeable cells.

For Battery packs that contain too many battery cells, since battery cells voltage and capacity are not performing the same all the time, that’s why BMS comes out. A BMS is a simple electronics system to measure and control voltage and current. and it will stop charging when the desired voltage is reached.

For example, in 10 cells pack, some battery cell may reach its full capacity already, while others might only 80% full. In case battery cell are already charged full, the BMS will shut down the power flow, in case there is no BMS, the already filled charged battery cell will go on with the charging and thus will short its life or even cause heat or fire.

Our BMS can monitor many more factors such as temperature, humidity,etc.. we can even send data to computer or App, so your customer can read the data on time.

Custom BMS for Your Lithium Battery Pack

  • Custom Any Size: Small, Big, Round, Strip
  • Custom Voltage Range: 3V ~ 120V
