FAQs 6

What is a BMS in an e-bike battery?

The main role of the BMS in an e-bike’s battery is to make sure all the cells of the battery are in balance during charging and discharging. “Cells” of a battery pack are actually cell blocks, made up of multiple 18650 cells in parallel (to give additional current capacity). Each cell is thus the voltage of one battery, which is around 3.6V.

How do you connect a BMS to a battery pack?

Connecting the BMS: B- Terminal: Connect to the main negative (-) terminal of the battery pack. B+ Terminal: Often already connected internally; check your BMS specifications. B1 (or B0): Connect to the most negative point (first cell's negative terminal). B2, B3,: Connect sequentially to the positive terminals of each cell in series.

Do You need A BMS to charge a battery?

A BMS is a delicate issue. There are actually people who believe in charging batteries without a BMS, like this guy on YouTube: He makes a lot of good points. Essentially, if you have a charger that can balance all the cells, you don’t need to use a BMS for that purpose. Firstly what does a BMS do?

What is the most important part of a BMS?

The most important part of a BMS is the size of the battery pack it’s rated for. You might know you have one of the following battery pack sizes: 24V, 36V, 48V, or 52V. These are the most common battery pack sizes (36V seems to be the most common out of all of them). The size of the battery pack dictates how many cells you have in the battery.

Can a new BMS be soldered to a B0 battery?

Note: If your new BMS has a B0 wire and the previous one had none you will have to solder it to the B0 battery nickel strip, there is no work around on that.

How do I install a new BMS?

There are three steps to installing the new BMS. Firstly, remove the connector at the top. Mine is a 14-pin connector; you might have 10 or 12 pins or some other number. This should be a plug-and-play replacement for your current BMS. Secondly, use a low-power soldering iron to de-solder the three connectors at the bottom.
