Batteries in Open source electric vehicles are based on the Open Source Battery Project.
Open Source Battery Project
The OSBP4EVs is an attempt to gather the expertise of many to design low cost battery solutions for Electric Vehicles and Hybrids, in a good solid 'Open Source' design.
We feel that inexpensive DIY batteries of this type will give home built EV and Hybrid vehicles greater range and provide more options for the builders.
Also you will have the opportunity to understand the battery, chargers and battery managements systems better than ever.
