Any relay that's rated for the amps your pushing should be legit.. you talking something you can turn on/off with like a GPIO pin or something or what?
So I was thinking I would use the LOAD terminals from my renogy Rover MPPT controller. One of the modes is a low voltage cutoff. My understanding is that it will disconnect LOAD terminals at 11.0 V which should work just dandy from a "protect the battery" standpoint. I am not really sure what my other options are for a low voltage disconnect, as the Victron indicates it can't be charged through.Any relay that's rated for the amps your pushing should be legit.. you talking something you can turn on/off with like a GPIO pin or something or what?

Are those listed for continuous duty?Ray I dont know if you have found a suitable relay yet. I have used these automotive "diesel glow plug" relays and they are good for 200Amps maybe overkill but it will never burn the contacts $17

sorry that one is not but this golf cart relay is 12V 300amp continuous dutyAre those listed for continuous duty?
A lot of those that say they are rated for 300A continuous aren't really. I have these, TYCO ev2000aaana rated for 500A. They are the ones used in the trucks that the Valence batteries come out of. Here's some on ebay https://www.ebay.com/itm/TE-Connect...584029?hash=item4454914a5d:g:hnAAAOSw4gVeMIm3Note: Normally Make 80A as Working Current, Need Break 5 sec on, 50 min off -/ If u need a long working one, pls note us.
The ebay seller, responded with this as well. Does that sound like the right approach?charger was set to 14.6. I'll try discharging to 10v but would that really make up another ~100 AH? the problem is that they don't seem to hold a charge over 13.4v
Thanks, I did amd neither one would hold a charge above 13.3. Ebay seller is actually issuing a refund! Thanks for responding!Not really. But I don't have that battery. I have the smaller Valence RT batteries and they have an internal BMS and don't require an external BMS.
Only thing I can suggest is to test the batteries separately. That would be very telling.
Just curious. Did you capacity test each one. The resting voltage is around 13.3 volts.Thanks, I did amd neither one would hold a charge above 13.3. Ebay seller is actually issuing a refund! Thanks for responding!
I did not capacity test them individually, noJust curious. Did you capacity test each one. The resting voltage is around 13.3 volts.
