Thanks Rick for your comments and commitment. I am currently building my second 20aH battery, its just minimally breadboarded now. I have the two batteries connected to a Cerbo and find some int...
Hello I am interested in this posting. I will trying to connect 4 LFP batteries in parallel using 4 REC BMS units. My plan so far is to use a Victron BMS-712 battery monitor and/or a Victron Cer...
Thanks Eboat, I am up and running with the REC configured on the Cerbo. Follow up question, have you set up a trigger on relay 1 or 2 to switch based on the BMS SOC? I could see possibly fooling t...
Hello Eboat, Thanks for the reply. I will try this response once again. I did try as you suggested using the 250kb/s selection. I assume if it worked I would find the REC BMS on my device list? ...
Listen to the boot up of the BMS. When I do I hear 2 separate clicks indicating the relays are functioning. If that is working, Using the wires from the main connector, Tie pin 5 (fused input to r...
Hello, I have recently integrated a Victron Cerbo device that provides a lot of usable information to the Victron products that I have connected to it. Can anyone discuss the steps I need to take t...
Thanks Rick, Unfortunately because of the physical locations of the batteries on the boat, my charge/discharge cables are at different lengths. No way around that. They are 4/0 cables, which wil...
Hello I am starting to build my diy battery drop in box. It is designed to drop into a 8D fiberglass battery compartment. I assume it’s ok to cut most wires to make the build a bit cleaner. I wi...
Hello Can you please tell me if the switching channel in the REC signal lines labeled DHC F & DHC NO can directly drive the Tyco EV200AAANA without blowing the BMS internal slow blow fuse? T...
Thanks for your reply. Yes I understand and think my small battery capacity can alter the effect of the algorithm as compared to what I will have on the boat. I do realize they measure SOC by two d...
Hello I am still learning about the 4S REC BMS. My question this time is related to the SOC. I question the accuracy of the process used to determine the SOC. For instance, I charge my small 20 ...
Thanks Blaine, very helpful information.
Thank you for the diagram, but I am looking to control the Blue Sea’s unit from the REC BMS. Can you help with that configuration?
Hello, I am interested in using the signal relay1 - user defined normally closed (pin 1) of the main connector. What are the specs and pin type I would need? My request is from the need to draw...
Why would full scale for a 4S configured BMS be set at 34 volts? Isn’t 4S by definition a BMS for 4 cells with a max voltage somewhere around 18 volts no matter the chemistry of the cells? This wo...
Thank you Tine. That was helpful. I opened the program as an admin and that must have changed the windows restrictions permanently. I am just learning about the BMS and have multiple questions....
Thanks Rick, this is one of my questions that I did figure out as I found it in the online manual. My next question is how do I post a new question. I can’t seem to find that on the website.
