Leaf Battery Alternatives?

Finding Nissan Leaf batteries is turning out to be a little challenging. I am persistent and will eventually find some.

My question for the group is, has anyone used others? I have seen the antiscab video from 2011 but seems like things must have evolved from there.

I found these on Battery Hookup and it would seem feasible although you would need to use quite a few in parallel to accomplish the necessary amp hours.

Any thoughts?

Re: Leaf Battery Alternatives?

I have not tried those, nor heard of anyone doing it, but I have seen people use other battery packs. I think someone used a Chevy pack from a Bolt? Volt? I remember it was inexpensive at the time to get those packs, but if it's the Bolt, I would worry about fires.

My FAVORITE one is someone did a 3 pack of Tesla cells. Not actively cooled, but with the little energy that is drawn from them by the bike they won't get too hot, and with even a 6.6kW charger they won't either. I loved that I think they were getting more than 100 miles range. Plus the supply of Tesla packs hasn't dried up the way Nissan and Chevy packs seem to have.

Of course the Tesla pack needs SURGERY done to the pack, which is a bitch, while just buying a full Nissan pack and selling the unused cells could pay for the full pack.

Re: Leaf Battery Alternatives?

Thanks for the feedback Randy.

Most Teslas use either 18650 or 21700 cells. I could go that route, it's just a lot of welding and I would need a lot of them in parallel to get to a reasonable range. I would prefer not to because a single bad cell is very painful to find and replace when they are all welded up.

Re: Leaf Battery Alternatives?

I don't think there is welding, just cutting of the metal plates on the outside to change the voltage of the pack from 24v to the 150v we need for the bike. I am not sure how much a bad cell will bite you on a Tesla pack as there are so many in parallel that one gone bad will only affect going to the very bottom of the battery. It's pretty rare that I go there. And the Tesla packs are pretty good at maintaining their balance. Not sure if the BMS they have can be re-used on the Vectrix.

Hi Randy,

Thanks for your feedback. I would need to see what you are referring to. The Tesla packs I have seen are configured at 400v using 3.7v cells in series. They are massive trays that ride on the underside of the main cabin and would be too big for this purpose.

I think the Leaf batteries are probably the best route for now. I was hoping to find Gen2 for the range but may have to go with Gen1 as there seem to be more available.

Re: Leaf Battery Alternatives?

Sorry if I was obtuse, the point is the modules are only 24v so to get to 400v you have to put a bunch of them together, but if you can only fit 3 into the belly of a Vectrix you need to split them into smaller packs that you can connect in series to make the 150v the bike runs on. The article is on this board on what was needed to cut the plates if people are interested.
