Wow. Cool photo. Thank you

HMmm. I appreciate your thoughts. The alternator builder said the hottest part would be the back of case behind the diodes. He does all the local fire truck and military alternators. He doesn’t know LiFePO4 batteries. But Wakespeed takes care of that. I probably will add a second 4/0 cable...

Hi. Agree with all that. I was collecting my own data not a realtime dashboard from Wakespeed. I measured the cable terminal temp with an infrared gun after manually checking different points and connections for hot spots. I just don’t like the cable terminal at the alternator positive post...

Since you guys are using Wakespeed, I'm curious have you measured cable temperatures at the alternator positive output stud? I installed a full Victron system for a customer, including 4 x 330Ah Victron 12V batteries (+ 2 3VA inverter chargers, 1500W solar, etc). I fired up the Wakespeed for...

I sent a Direct Message to @SignatureSolarChris and @SignatureSolarJames @BenFromSignatureSolar @SignatureSolarTech I'm having the BMS alarm issues with a 12V - 400Ah Lifepower battery I bought back in January '23. And just installed a month ago. I have 3000W Victron Multiplus. The BMS...

Good thought. I intend to mount in on the back / rear. so the cells would only have their own weight. This is also a mobile application.

Hi Danke, Thanks! interesting. The mfg says it can be mounted in any orientation. Since they do the warranty, I'll go with that. The application isn't stressful. Mostly very low loads and charging rates. <.1C. Doug

Hi Jay, Thank you for the reply. I did hear the same from the folks @ signature solar. I did hear something slightly different from members of this community on 200Ah EVE cells, which given the same chemistry I'd assume the same guidance. In any event, I'll proceed with this installation. Doug

Will and David Poz, I believe have tested these EG4LL server-rack format batteries with high marks. https://signaturesolar.com/eg4-lifepower4-lithium-battery-12v-400ah/ Can they be mounted in any orientation? For example on the small side? I want to mount under the RV dinette. The base is not...

I would call a solar wholesaler / supplier and ask them. It never occurred to me you couldn't find 60 cell panels. I have 3 on my RV for 3 years. I assume they'll last a very long time, since they only see 4 to 6 weeks of use each year. And normal are 25 year rated. Why not buy a spare panel...

Tim, Good point. but then again, when you plug the harness in, there is no guarantee all connections are made exactly at the same time. Doug

I'm looking at one of these 5A versions for my 560Ah 13.2V pack (pairs of 280Ah are wired in parallel with 1 BMS). My C rates are very low. RV application. Highest load is 125A for air conditioner. That happens 2 X / year for a few hours. Charging is normally solar - up to 45A. Normal...

Tha k you for that feedback

I have 300W x 3. 60 cell house type panels. I've seen as much as 650W out of the MPPT (Magnum) SCC, never real close to rated. And that'd be with maximized geometry (mid day sun). And mine our mounted flat. Given your description, I'd expect less efficiency. The geometry of your panels and...

In my 10S clip i do see wide variation in cell level voltages on each. All vary at least 40mV and cell 3 varies by 70mV. This could be a statistical anomaly. I didn’t take more video. They sort of seem consistent. Is the same reported on all ED BMSs?
