Need help for diy lithium battery integration. We have rx-60 forklift, battery was leaking acid 80v 560ah and we have changed to diy battery from lg chem cells used in kona electric 4.2v max min 2.8v.

Now battery specs 22s3p 180ah max 92.4v min 66v. But we have an issue : our battery showing 40% left 78v on bms but the forklift screen showing 0%
amd forklift moves/ works like with empty battery.

Main question would be, what to change in forklift setting to let it work in lower voltage?

Ps forklift worked 3 moto h before that, everything is working properly. Any advice would help
