Battery Management System with Charger - PCB Layout + BOM

We are interested to buy PCB-Sources of an existing Battery Management System (BMS) with Charger. We need a PCB Layout for EAGLE or Altium, Documentation / User Manual and a BOM, incl. all informations for production (that includes sourcecode for microcontroller, too). We don't need a housing - We'll build or own. The BMS must be able to charge this types of batteries: Lead-Acid from 50 - 120 Ah AGM from 50 - 120 Ah As Input we need: 230V AC 14 - 24V DC (comes from generator) Perfect would be an additional 14 - 24 DC input System should be able to show the State-of-Charge, State-of-Health, Current consumption in Ampere & Watt and also should have warnings before deep discharge would happens. So it would be good if a display is on the PCB for all this informations. Some other Requirements: Temp.-Range from -40°C to +85°C RoHS & CE Conform Batteries should be loaded with up to 15 Ampere You should be able to send us a datasheet or manual of the system that you can offer and also the total costs of the BOM. Thank you very much for reading. If you have any questions, feel free to contact us.
