1. Use a voltmeter or battery tester to detect the voltage of each battery string and find abnormal batteries.
2. Disconnect the positive and negative terminals from the battery string.
3. Remove the replaced battery from the battery pack.
4. Install the new battery into the battery and connect it well.
5. Close the battery case, turn on the power and check if it is installed correctly.
6. Test the battery voltage again to ensure all batteries are working properly and have the same voltage.
Xingheng ionic battery is good.
Regarding your question, I think Phylion lithium batteries are better. Phylion lithium batteries are good quality because Phylion lithium batteries are manufactured using new technology and new processes have a longer battery life. lifetime. Heis long, has large power capacity, is very cost-effective, and has a good reputation. The Phylion lithium battery can be said to be a dark horse that has been hiding for many years. Phylion's main product is lithium manganate battery. Its advantages are low cost, good resistance to low temperatures and energy density suitable for low-speed electric vehicles. After years of research and technology development, Phylion has mastered the basic manufacturing process of battery cells. And it has achieved the first position in the market in advance and is also the only low-speed lithium battery company with annual sales above 5 million units.
