I got a Jiangsu Xinri E-Grom clone with SLA batteries that are tired and need to be upgraded. It currently has 72v 32ah of lead acid in it. I used to do 46mph according to the gps, but only does 41-41mph now. I've been looking at getting some 70% capacity Nissan Leaf Gen 2 cells tested at 41-43ah from Greentec Auto. I think I can get 10 of them for around $600. I was also looking at possibly doing CALB Lifepo4 40ah cells but that would be more than double the price and maybe a little bit tougher to fit them all in the chassis. I'm looking for recommendations on how you guys would run your setups or what batteries you would choose. I also thought about running Chevy Volt cells but I haven't seen them as cheap or available as the Leaf cells. I'm also not sure how to connect individual Volt cells if I need to split up the pack to make it 72 volts.
Here's the measurements of the battery tray. I believe I can get 6 Leaf cells laying down and 2+2 on each side of the main chassis bar for a total of 10. I think I could possibly get 2 more on top of the chassis bar for 12 cells if I cut the plastic fake gas tank or maybe fab up one outta sheet metal. If I could find another plastic gas tank I would cut it up, but replacement parts are hard to find in the states.
If I go back 12inches from the front of the battery box, I can get about 8.5 inches in height which I believe should clear 6 Nissan Leaf cells stacked up.
Width of battery box from bottom
Then I was gonna put 2 on each side of the chassis bar like how the current SLA's sit.
Should kinda look like this.
