Iota DLSX bulk charging plug?

Hey everyone,

I recently bought a used Iota DLSX-75 battery charger, without knowing that the DLSX series has been discontinued. The charge controllers for the DLSX are no longer available, and unfortunately Iota says that the charge controllers for the regular DLS series won't work.

I'd like to be able to occasionally use bulk charging mode. (meaning stepping the voltage up to ~14.2v) There's a simple plug that can be installed in the regular DLS series to force bulk charging mode without having a charge controller. Does anyone know if it's possible to do the same with the DLSX? Iota technical support has not been helpful in this regard.

The bulk charging plug for the DLS uses a 4 pin RG-9 connector, where the DLSX uses a completely different 6 pin connector.

Thanks in advance.
