    Bump - can anyone offer any insight on this?

    Cell Cap. Voltages for BMS

    I’m using 3x DIY 190ah batteries each with a 4S Overkill Solar BMS. What Cell Cap. Voltages are recommended for 10% up to 100% and everywhere in between? These are my current settings which don’t seem right:

    Solar output drop, unsure why.

    Got it, for some reason I thought panels were more dictated by volts than amps, as in amps we more of a constant if in the sun and it was the voltage varied. Now I feel stupid. I appreciate the replies!

    Solar output drop, unsure why.

    So even though the panels are hitting their max voltages, they will produce less watts? Sorry my knowledge of panels is limited. Edit: I'm in Colorado

    Solar output drop, unsure why.

    I have 2x 200W panels on my van that were producing around 350W Pmax a few weeks ago (closer to 400W P max in summer). I just noticed now that output is around 200W P max. The V max is the same at around 40V. I cleaned the panels as they were a little dirty, it made a little difference of about...

    Battery Case

    Also, for anyone who comes across this post later for the same reason - $80 is a decent deal on these cases!

    Battery Case

    Yeah I've seen those, very nice!! But I really only need the case so spending $600+ on 3 cases is too much.

    Battery Case

    Thanks but I'd order then from Ali if I had the time to wait - I'm looking for something available now. Good idea to bring some in though!!! They're impossible to find in the US.

    Battery Case

    Thanks but that's the one I don't want.

    Battery Case

    Anyone know where I can find a battery case in the USA? These ones are quite bulky: I'm looking for one like this but can only find them on Ali Express (I'd like one from a US supplier to get it ASAP).

    Adding batteries with different SOC

    Hi all, I have 12x 3.2V battery cells. They've been split into 3 separate units of 4 cells in parallel in order to level out out the voltage (since I wasn't planning to use them for a little while). Each battery the 3 batteries has 4 cells with the same SOC, although each battery has a slightly...

    DC-DC Chargers in Parallel

    I think you may be referring to the non-isolated version? I purchased the isolated version. I haven't got to the wiring of them yet, although off the top of my head I think I will wire them independently of each other (perhaps with another busbar at the battery so the terminals are clean & I can...

    DC-DC Chargers in Parallel

    Hi, I haven't installed this yet (the build is slow with kids and a business) but I have all the parts in my garage and I have decided to go this route of wiring the two Orion DC-DC outputs into a busbar (one for + and one for -) then feeding from the busbars into the Lynx Distributor. I've...

    DC-DC Chargers in Parallel

    My Lynx Distributor has no room for the 2nd Orion DC-DC and I'm trying to avoid getting a 2nd Lynx Distributor. Can I wire the Orion DC-DC units in Parallel from the Starter to the Orions, then feed their outputs onto small busbars (one + and one -) that then feed as one cable into the Lynx...

    DC-DC Chargers in Parallel

    In hindsight that now seems very obvious! Not sure why I didn't think of that... Thanks!
