eBike battery charge status indicator

If you take good care of your ebike battery, you'll have a fancy carger like me that can charge your ebike battery to 80% (for storage), or 90% or 100% when needed.

To keep track of the charging status I designed this... thing.

You can select the amount (80/90/100%) and if the battery needs to be charged or not.

Oh, and do your self a favour and buy a fancy charger, those cheap supplied charger don't protect your battery from overcharging. Rule of thumb: if your charger feels light, buy another one.
