Won’t Turn Over

Dec 23-24. 52’ Fahrenheit, stored indoors
I have an AIH Texas chopper 2000cc S and S engine, NLP20
I have only started the bike about 10 times
It worked good til now
On the third attempt all the power went out
I disconnected it
Recharged it with a NOCO 2 amp lithium charger
The lights now come on but it won’t engage the solenoid or move the starter
I put in my old lead acid battery and it moved the starter
It’s a big ask to get that engine to roll over in less than 70’ Fahrenheit
For either battery
NOCO should make a higher amperage battery in the NLP20 case as an option
I don’t have room in the battery box for a larger unit
I think the battery management system died,
Anybody know how to revive it?
