Looking at the 2Q manual it looks like if I want OV and UV disconnects, then I can't use the standard Opto-Relay as it is only intended for controlling a single contactor. So I'd need to use the O...

Rick,Thanks for the reply. It sounds like you recommend a single contactor/relay?Regarding precharge: I understand that when the contactor switches you want the pre-charge to ensure you don't get a...
I'm looking at at least two contactors (actually EGIS relays), one for the charge bus and one for the discharge bus. My current design (which I'm reducing as we are changing from 12V to 24V) has 2 ...
@Rick Thanks for the pointer to the git repository. I am a tech guy, but hesitant until it's fully tested to put stuff like this on our boat, unless it's a system that I can live without.It wi...
I've been contenplating installing two seperate 12V LiFePo4 banks rather than just one. What would be the best way to do this with REC BMSes? I know there are the 2Qs, but they seem to be for...
John,I considered the Blue Sea swtich - it's a good switch (I have one and like it), but for my Lithium I wanted a smaller more compact solution which the EGIS seems to provide - I'll know when I p...
Here is what my system looks like.(as a reference. Hopefully nobody finds mistakes :) )

I wanted to share what I've found as it might be of value to others. My system will have a Load bus and Charge bus, so I need two contactors/switches. Initially I was planning on using the standar...
@Ben Thanks so much for posting about the TBS - it looks like a great solution which made me go looking some more!(I'll be posting in a new thread about this)
Rick,Thanks for the update - things make more senses now!One question - on the updated diagram shouldn't pin4 (Pack+) go to the battery pack side of the contactor?For an actual install should you h...
Rick, Thanks for the feedback. The only diagram I could find that uses the V3 pre-charge is: https://rec-bms-na.com/download/31/rec-active-bms-sketches/1290/rec-active-bms-wiring-diagram-rec-acti...
I'm currently planning our my upgrade to Lithium from Trojan T105s and am wondering which pins on the REC Active BMS should connect the following to:- Victron Battery Protect (for charge disconnect...
