Judging from all the advice here, a Tesla battery pack seems happiest when operated around 50% SoC. So you charge it to 70%, drive it down to 40%, etc. I'm curious to learn how well this usage rhythm would apply to an electrical bike battery. For the Batavus Padova Easy (Dutch brand) with a lithium ion battery (unsure about the exact chemistry used), the official advice is to keep it connected to the charger as much as possible. My gut says this isn't particularly great for the battery. What are your thoughts on this?
