I am about to pull the trigger on EVE cells, about 300Ah each (not sure if 280 or 314 or something in between) for my sailboat. My current battery is 740Ah of AGM, and works wonderfully -- this would indicate that I should go with 8 cells (2P4S) for a significant step up in available power...

I have a sailboat, and am about to upgrade the existing panels (an accident has shattered my existing, so a chance to redesign). A simple replacement with identical panels will get me about 600W. I'd like to get over that. For starters, consider money to not be an issue (of course it is, but...

I have a 43' sailboat, currently with 800Ah of AGM. Over the last 3 summers, I've been aware that they aren't long for this world. Yesterday, I used a heat gun with the inverter, and in under 5 min I had a "low voltage alarm" -- and my batteries were at 100% SOC when I started. Not sure the...

Not sure if this is the right subforum, but it seems right. I have a simple (ha!) system, consisting of 4 BlueSolar, a 3kVA Multiplus, a SmartDongle, and a Battery Protect. My BMS (ElectroDacus) is not Victron-friendly (at least out of the box -- apparently it's not terribly hard to make it...

I'm getting close to building an LFP pack for my boat. It will be either 2P4S or 3P4S, using EVE cells around 280Ah. Either studs, or if I get them from 18650 then the two hole version (which I like). Especially for the 3P version, bus bars are a challenge! I'll be fusing the battery with a...

I asked this on the Victron community, and the silence is deafening. I hope it is better here. I have a Mutliplus and a BP in my new LFP install. The BMS (ElectroDacus) has a single opto output for "allow to charge." I need to have this turn off the Multi and the BP. Both have "allow to...

I bought a Finirsi HRM-10 resistance tester to hopefully help with my new LFP setup, or at least to provide insight. It tested cells very well, providing consistent/repeatable readings on each cell (and showing that the cells were very close). I am not posting a link, as I am not crystal clear...

I'm trying to settle on a BMS. My power needs are fairly high, potentially over 300A both charge and discharge. Also, since it is going on a boat, I have to be aware of ABYC (building code for boats) requirements. Also, since it's on a boat, I have space and power constraints. So, that said...

I have just received a dozen EVE MB31 from 18650. Well packed, look good, fingers crossed. I also have a FNIRSI HRM-10 resistance tester. I've tested all cells, and now don't know what to think of the data. Looking for advice! The meter on resistance would dance around, I recorded high and...
