Chances of depleting this battery in normal use are nil unless you end up driving to Berlin from Amsterdam or so :) It can go up to the country borders in every direction.

The added weight is 130 times 50 grams + the weight of the enclosure. 170 batteries in there, but the original battery already had 40 of those.

Agreed that you don't want to pedal it uphill without the motor running that would get old really quick.
