Have you tried Battery Bill... batterybill.com

Why not something as simple as a dual zone automatic transfer switch. e.g https://www.ebay.com/itm/GCQ2-63-2P-63A-Dual-Power-Automatic-Transfer-Switch-ATSE-Switch-CB-Class-Switch-/174427269392

So how about something simple like.... 24v--> DC to AC inverter --> AC to 48v charger? Simple and cheap.

Theoretical vs practical. Theoretical.... don't go there. Practical. 35mm wire should be fine because.... a) your batteries will die long before you will heat up/melt the wires and b) look inside the inverter. You will most likely find substantially less wire sizes than you think.

I have 48v Lifepo4 batteries with the brand Deutche Technologies. They have a KYHT branded BMS inside (see http://www.kyhtbms.com/goods/show-135.html). I have tried contacting local battery supplier and the BMS manufacturer but have no joy in getting a response. Does anyone have any information...
