What is the voltage of lithium battery pack
Looking at a Sanyo Eneloop bicycle circa 2010, battery packs no longer available even from Japan (Amazon or Rakuten). The bike has a 250W brushless motor. The battery pack is stated as 25.2V 5.7Ah. Most 250W motors today are 24V. So I''m wondering why they would have used a nonstandard lithium ion 25.2V battery pack... must be 7 cells?
