Hello everyone ,
I wanted a small electric bicycle scooter without having to issue papers insurance and all that for me and my girl so we can roam the city cheap.
The electric bicycle-scooter i took was the best in Greece at the moment but as always i want to improve some of its features.
The technical specifications of the bicycle is 250 watt rear hub drummed motor 20A controller 48 volt 12Ah Lead acid batteries.
The bicycle has a lot of tongue even with two peoples riding it but the controller gets really hot when i climb hills with a second person.I think that the controller gets hot because it is enclosures in the body of the bicycle and because the motor runs in 20A when i climb a hill.I was wondering if i can do something about that to improve its temp please let me know.
Also the bicycle has 60KM range with one person and 40-50 km with two persons.For now i am not thinking investing in a Lipo4 battery but i will do it in the future after the lead acid ones die.
So i derided to make a small project that will give an extra 10KM of charge when i need it.I was thinking to buy a small inverter 150 watt and take a 4s lipo pack's at 5Ah and use the inverter with the bicycle charger as an insurance in case i run out of battery.The only think i am not sure is if i can use this kind of setup while the bicycle is running because i don't want to discharge my lead acid batteries more than 50%.Do you think that is possible ?if it will help i can also provide you with the electric bicycles electronic schismatics.
Thanks in advance
Andreas
