You NEED to check out HPEVS, they have a 140 AH plug n play Lithium Battery for $5k. Not sure what it’d take to make it work with the Navitas setup as HPEVS has their own AC Drive setup using a Curtis controller and an HPEVS AC Motor but 140 AH is some serious range..

I have an Onward with Navitas AC conversion/600a controller on the stock lead acid batteries. I'm underwhelmed with acceleration and battery life using the oem batteries and want to upgrade to lithium. I'd prefer a "plug and play" setup because I don't feel comfortable piecing together a kit myself and am unaware of any local to help.
I looked into Roypow but heard from 2 different dealers that they have issues with voltage drop on the Navitas setups and haven't figured out a fix.
Looked into Allied, more expensive, and not sure if they figured out the battery balancing and charging issues.
In your opinion(s), what would be the best setup as far as:
1) safety
2) reliability/longevity
3) best suited for my motor/controller
4) price
in that order
