Just as a point of interest. I weighed my Freego Eagle battery which is 16ah and was amazed that it was actually 5.5k. would this be a normal weight or are more modern ones lighter. I don't actually need such a big battery so when it is done I will go smaller if I still have the same bike

Batteries are getting smaller and lighter. Your Freego battery may be a LiFePO4, heavier and bulkier than the more usual Li-Ion or Li-po.

the weight of your battery depends on the type of cells inside. Best for weight batteries are usually built with cylindrical 18650 cells.

I think it's full of bricks like a night storage heater

A modern 36v 16Ah battery would weigh about half of that.
