Has anyone gone down the lithium battery route ?
If so which make?
They are a fraction of the weight, perform better and have extended life compared to lead acid equivalents.
The Caterham guys use the Powerlite PS-20 which will fit the original battery tray and has over 400 C/A.
Wonder where you read about the extended life compared to lead/acid.
Tesla I believe guarantee 80% capacity after 8 years. They are able to offer this because they double the 100% capacity ex factory and initially charge to 80% of this and discharge to 30% gradually scaling the range up until using 100% of remaining capacity. Clever eh!
