Hello and welcome,
Ive lurked for some time on this site, but first time posting.
I have a 2008 Zenn (for those who dont know, its a Microcar MC2 extended wheelbase) that was converted to all electric here in quebec, with the numbers of plated Zenns dwindling down i come to a hard decision to make really soon...
Last time i checked there are about 11-12 left on the road here in quebec, and on the facebook group there may only be another 60 that remain in existence in the US-Canada market.
The zenn runs off 6 deep cycle-agm 12v DC batteries each 100-105AH rating, meaning about 7kwh of energy packed into a 1000lb go cart/golf cart. Which means the motor, and charging are set up for a 72v system
One of my batteries is finally letting go (second set in its lifetime, none of which i purchased).
Seeing how the pack is pretty worn i cant replace just one battery (or two) and would ultimately need to replace the whole pack.
Here in canada we are talking about 300-350$ a battery, times six, making it an 1800-2200$ expense with taxes... for a car that does ~40km per charge at 40kmh...
And heres where I need your help... I have three options as far as I see it
option A, get a new pack and forget about it for the next 5 years
option B, do a li-ion swap, for which ill need the community's help as to finding the best bang for buck for making a pack, charger and balancer, would probably double the range but i would need a new motor/ecu for any speed increases. buying a 100-105ah 12v battery seems to go for in the thousands for one...
option C, swap it to an infernal combustion engine... which would probably be the cheapest option but require the most work too.
the car doesnt drive in the winter and gets limited miles in the summer, its basically a groccery getter at this point due to its dimishing range...
(has about 2000km on the odometer)
So what do you think i should do? im mechanically verse with all sorts of tools, a decent enough understanding of how EVs work...
