When you go to sites selling LPolymer like "battery space" you can see all kind of warnings,
As I said everthing is fine as long as charging electronics works , but when they fail I would not be anywhere close to the bike with LPolymer battery.
If charger electronics fail and allow Poymer cells to be overcharged you look at fire.
It just chemistry.
Ask me why they offer LPolymer safety charge bags for sale, why they say never leave the charger unattended, why pople charge LPoly in ovens or enveloped by bricks, they must be a reason for that.
I would never buy a bicycle with LPoly cells just meter behind my back.
