My battery is RITAR (generation 1) (lifpo4 25.6v 100ah 8cells) G1 haven't any communication interface ports or On/Off button. But BMS board inside its support CAN bus/RS485 already built-in. Only generation 2, 3 have CAN/RS485 and others interface. Instead of changing the all BMS boards with supported RS485 port i decided to make the communication interface port for RS485 as long as its built-in on existing BMS board, im only a user "not an engineer" learn many things from your posts.I didn't run anything yet, the picure for BMS Software from the Ritar menual the battery is G1 i don't know whats Software is compatible with its yet

I did not connected the battery bms to RS485 communication interface yet Your english is very good and simple clear. it my understanding to english my apologies

Thank you for your helps, i appreciate Also i found in battery bms connector 3 next (A B text) there's (ic MAX485) that makes more identifiable pinout of CAN bus H L and RS485 A B But the Ritar menual say the battery BMS default ADD is 0, if the battery needs to do communication with inverter or there are 2 or more batteries connect in parallel. it needs set ADD . and setting configuration needs to *connect CAN terminal resistor (120 ohm) to last battery down RJ45. * Automatic coding part (pin 2;3 short together) to first battery up RJ45. *then pressing power button for 6sec. As its showing in the picure connector 3 have 10 pins i don't know where is pins 2;3 (pin 2 in up (O/F/LED+) down (SWB) pin 3 in up (O/F) down (SWA) In Ritar menual "BMS Software old" there's "Dry Conn1;Dry Conn2" can i setup modbus id or ADD master and slave for two batteries by bms software only for each one ?

I think Ritar battery G3 hasn't DIP switches the add 1 activate and configured by power On/Off button ( pressing for 6 seconds) after connecting terminal coding to last BAT (CAN RJ45 pin 2, 3 short together) according to menual https://drive.google.com/file/d/1PI65vDR28mE7Mw02WT_aQThAx3Ma9jf3/view?usp=drivesdk

In battery bms is RS485 are dual channels or only one, i mean transceiver is 2 or 1? Also if you look in picture connector 3 you will see onboard printed (H L) and (A B) may be for (H L CAN; A B RS485) I try to upload some more pictures to identify but its work.

Hello, I have two batteries LiFePO4 25.6v 100Ah (Ritar G1) in series, without any communication interface ports. And the inverter (voltronic vm iii twin 6000w 48v). The inverter was not recognize batteries gives bp error (now it is working after many try). So i want to make RS485 or CAN ports if its possible. I think (RS485;CAN) are built-in on BMS board but without com interface ports. I attached some pictures to identify which BMS connectors is RS485 and CAN? I hope you can help me and thanks in advance.
