Hey Noreen,Thank you - I probably should have found that myself. Appreciate your pointing it out to me.
For lithium battery's, depth of charge is more important than the number of charges. Your battery will supposedly last longer with a lot of little charges, than fewer deep charges. The thinking is if you charge after every ride your battery will last longer , because the depth of the charges won't be as much.
It's also considered good practice to let your battery cool off before charging.
This is probably the case with LiFePo4 battery's but other chemistry's like Manganese or Cobalt may have slightly different property's.
There's plenty of discharge graphs from battery manufacturers for depth of discharge and capacity and they all show longer battery life if you limit charging to less than 100% and discharging to greater than 0... Just not my experience!
I wonder how the percentages are determined on my somewhat closed system on my Stromer. I have a light that says done when charging, hard to stop at 90%. Also I wonder if the battery cells in a different branded battery use the same voltages for the fully charged and discharged states.
