Thank you. This was helpful. I just set my float to 52.5V. I want it to cycle sometimes. There are a ton of terms in that document that would benefit from a bit more detailed explanation but I could've googled if i wanted. it was still helpful.
What is the high knee?
Hi, thanks. I have been on...
I have read nothing from the recent posts but I see people struggling w/ cables (as always).
So... the main issue I found with DIY cabling is that the Victron Brand cable is isolated and the one from the old video that everyone suggests following is NOT.
I updated what to do here...
I've read all the things, especially @FilterGuy's resource on voltages. I previously had it set according to that: Absorption: 56.8V, Float: 54.4V. But it felt like the system was acting weird when I "barely" used the battery, which is often the case, and then it either did or didn't charge...
My Overkill BMS kept connecting and disconnecting over and over again. I was using the UART usb that came w/ the BMS.
and now my smartshunt wont connect at all. (the same cable effectively connects my smartsolar)
You'd probably need to flip some of the wires, since Victron likes to do that, but maybe. Would be an interesting experiment. If anyone wants to fund buying me a bunch of cables I can try and test it.
My big worry is that it's just sending raw data, and the shunt is what parses it and turns it...
The Victron Lynx Distributor is designed to be connected to either the Lynx Shunt or Lynx BMS for power and data, via an RJ10 cable. It can tell the VRM which fuses are blown. And it uses 5v power via the RJ10 cable as well.
I know I can power the Lynx w/ my mini 12v -> 5v step down board I...
Also. I was gonna heat shrink my bus bars between batteries to prevent potential shorts, but now I'm worried about heat dissipation after all this research, fuck.
I'm not using batteries with terminals like that. Mine have lugs. But still relevant info. Thank you.
I think I'm just gonna buy 1/8" x 1" copper. I'm probably over doing it on mine then. Which is great.
that sucks. we're doing our own repairs, for better or worse ?
48v 300ah battery on a 3000VA inverter. So i'll be hitting 65A nominal, 120A peak. I should be in a relatively safe zone. But like i said in OP. sub-par Aluminum in an enclosed space. I dont want it heating up. I should probably...
Pre-posting edit note: Hindsight I figured out while posting this, I had not matched the units' magnitude while comparing resistances, and they're much closer than I thought, by about 10^2. I am now fixating MUCH less, but still curious what people think of the differences between the two, so...
Need to know the voltage, the amps you'll be pulling, and the arrangement of the batteries you'll be using. As well as which 25mm2 cable.
You can probably do this yourself by looking up the ampacity provided by the cable manufacturer, and your knowledge about the setup.
