An e-bike battery tear down - mildly interesting if you own or are thinking about buying an e-bike. These batteries cost half the price of the e-bike and are not easily user serviceable.
Rich went to get a spanner from the car and returned with an E-Bike battery that was sick... so, we wanted to help out our friend ... and stripped it down to establish what the problem was... Our pal said his bicycle didn't have as much "oomph" as it used to... so we took it apart and found there was a cell that needed replacing... We were expecting to see high "C" rated 18650s but ... well... NOPE! - STACKS of BIG HAIRY LITHIUM ION PHOSPHATE cells... interesting... I'm sure this could be put to good use one day! :-)
