If that battery uses those Headway cells it should be a good battery.
The two wire connection
(Battery + and Battery -) is standard for most charging applications even though a three or four pin connector is sometimes used.
It should be possible to make up a simple adapter using a three pin socket to suit your charger's plug and then wire it to a couple of suitable Anderson connectors to match the Battery's charging connectors.
But I suggest that you check the output of your existing charger to ensure the output voltage does not exceed 58.4V or you may overload the new battery's
BMS.
