Issues with a Lithium conversion on LIDO golf cart

Hi All, I am converting a 48v LIDO (EZGO-WESTERN) golf cart to lithium. Battery in place and wired up. Issues is NO POWER to motor. I have 57v going into the coil but get no sound when I press the “gas” pedel. (like it is not making a contact inside) There is a light on the controller that blinks 2 times, short pause then 5 times. This pattern repeats itself. Just looking for any ideas on what I can try. Cart worked before the batteries were switched.
These lithium battery pack is Nissan Gen 3. I have converted two club cars with no issue. The current LIDO car is a 2001.
