How to test ebike battery with multimeter?

To test an eBike battery with a multimeter, you'll need to first fully charge the battery. Then, locate the positive and negative terminals on the battery pack, and use the multimeter to measure the voltage between these terminals. Make sure the multimeter is set to DC voltage and that the red probe is connected to the positive terminal and the black probe is connected to the negative terminal. The reading should be within the range specified by the battery manufacturer. If the reading is significantly below the specified range, it may indicate that the battery pack is not functioning properly and may need to be replaced. It's also important to note that if the battery has been recently used, you should wait at least an hour before testing it, as this will allow the battery to rest and provide a more accurate reading.
