Do ebike batteries still need regular balance charging even if they have a battery management system (BMS)? I believe that a BMS has no effect on balance charging unless it is an active balancing system, which e-bike batteries do not usually have. Therefore, batteries with an advanced BMS still require occasional balance charging. Is this view correct, or am I misunderstanding?

I want to assemble a satisfactory lithium iron phosphate battery pack so that it can do a good job of balancing, protection, data acquisition, and control of lithium batteries. Lithium battery protection boards and BMS are two good choices; what is the difference between them?

I am in the project’s initial phase and must select the appropriate lithium battery protection circuit board. Can you provide me with a guide?

Now that Bluetooth wireless technology is everywhere, we are going to use Bluetooth technology to upgrade our electric vehicles. What benefits does the utilization of low-power Bluetooth offer?

I am considering purchasing a BMS so that I can charge this laptop battery pack that has died. I’m wondering if I can properly connect the wires leading from the battery to the BMS and then just use a basic DC power connection to charge the battery, or do I need to install other equipment?

I plan to build six individual 10S2P lithium-ion battery packs. Each battery pack contains ten cell singles connected in series (10S) and two of these series cell singles are connected in parallel mode (2P). As far as the bms goes, what is the best way to connect them?

I made a new 10S battery pack, perfectly balanced, and all the wires in the 10P plug were connected in the right order. When I connected the main + and 10P plugs, there were two areas where the components would overheat. I have tried to connect all the wires and shorten the reset contacts, but still, both locations are extremely hot. what’s the reason?

Because the BMS of my electric car fails to charge, I would like to know what circumstances will lead to such a thing.

At first I bought cheap batteries, and the first 5 months without a problem, but after the battery BMS failure, I bought a new battery and BMS, installed and working well. But I wanted to know what caused the previous failure, so I disassembled one of the faulty batteries and tested its voltage. The voltage reading of the faulty battery is 13.45 volts, indicating that the battery is in good charge. However, the battery did not work when connected to a system that had bypassed the BMS, which further confirmed the faulty BMS. At this stage, can I try some methods to try to disassemble the battery and somehow get the BMS back to normal?

I was away from home, and my e-bike lost all power after I leaned it against a tree. Twice, the BMS cut off the power for no reason and could not restart until I recharged it. I tried to disconnect the power supply five times, but the voltage of the BMS remained zero until the charger was connected. Why did it repeatedly disconnect for no reason before charging?
