My EVT4000e scooter, li-ion project ?
Posted: Sun Sep 26, 2010 11:39 am
Well I've finally got my EVT4000e (orginally owned by GeekyGrilli ) on the MOT'd and on the road
Currently running it on a set of tired four ex UPS SLA 38Ah 12v batteries but it seems to perform not too bad on them, next stop is to try a Li-ion it up.
So the question has to be which way to go, I could go the easy route and order up a set of 30ah LiFePO4's from Ping which look as though they will be around £650 mark, but I'm not sure if this is the best route
Certainly its the easy peasy option as they come with BMS and a charger and they would drop straight in a couple of connections and away I go
I've got to take some amp readings just to see what it uses while going along to find out if a 30ah set would be ok but I am concerned that they wont be man enough as I've seen 100Amps plus from my meter just riding about in the garden.
What other options have I open to me before go plunging into a set of ping LiFePO4's
My one concern with a fully DIY option is all the BMS malarky if I get individual cells etc
