Why choose 48V lithium-ion battery?

  • Custom 48V lithium battery pack since 2010.
  • PCM/BMS customized available.
  • Provide RS485, RS232, CAN BMS Protocols optional.
  • Capacity, Size/dimension can be customized.
  • PVC wrap, ABS, Metal housing can be chosen.
  • Short-circuit, over-current, over-voltage protection.

How to charge a 48V lithium battery?

  1. Moderate charge. By charging and discharging lithium-ion batteries appropriately, battery life can be extended. The battery capacity of lithium-ion batteries is maintained at 10% to 90%, which is conducive to battery protection.
  2. Choose the right charging temperature. Lithium battery charging temperature range: 0~45℃, lithium battery discharging temperature range: 0~60℃.
  3. Avoid overcharging. Lithium-ion batteries must avoid overcharging during the charging process. Any form of overcharging of lithium-ion batteries can cause serious damage to battery performance and even explode.
  4. No activation for the first charge, standard charging time. The charge and discharge characteristics of lithium batteries and nickel batteries are very different. Do not charge for more than 12 hours, repeat three times. Charge according to standard time and method, especially don’t charge for longer than 12 hours.

Steps to Custom Your 48V Lithium ion Battery

  • Lithium Battery Cell Selection

    Now there are two models of lithium battery cell that is mostly used: NCM battery and lifepo4 battery. 

    While considering the cell selection, we would like to consider nominal voltage, capacity, lifespan, price and size. Their capacity ranges from 2Ah to 200Ah. 

  • BMS (battery management system) choice

    It is designed to monitor and control the charge & discharge voltage, current and temperature. Even before assembling the battery pack, we did complete battery cell match. It is necessary to monitor their internal performance.

    Otherwise, some cells are full charged, some are only 90% charged. It is out of cell balance. The whole battery pack only discharges 90% SOC. It will affect their running time. 

  • Assembly and get ready certificates

    It is ready for battery packs with work statement. It is vital to follow rule of simple and useful.

    We will apply relative certificates based on customer demands. It may CE, CB, UL, UN38.3, MSDS.
