agm to lithim mixed chemistry concern C-288

I'm converting a C288 with Agm batteries to Lithium The main battery switch conects to the windless and house main via a connecting bar on the backside of the panel . My concern is that the two battery chemistries appear to be tied together. My question is do I need to seperate the windless and if so where would I pull a agm power source from.

The contractor keeps the chemistries separate, it's just you use Lithium to engage the motor side of the contractor/relay, which I assume is AGM.

However, even if it was Lithium, the Lewmar 1000 uses about 50amps and most Lithium systems/BMS should have no problem supporting this load, even with everything else in your system. My lithium system had 400amps sustained output, even with motor starting surges, there was plenty of capacity. I ran my windlass (switch and motor) off my Lithium house bank on my R31.

The motor side is AGM
