Im looking to insteall this exact system and am glad I came across this thread. Great diagrams too! (what did you use for it?) The Victron Phoenix has a rest mode - it shuts off when no load is attached. Turns on to check for load every 3 seconds. Just thought Id throw that in here as I read...

Please do not think these offerings by BigBattery.com are "marine" While I have not specifically purchased any of these, I spent weeks going back and forth with BB trying to get information for these for use in my boat. They have no idea what is even means to be "marine", and Will's teardowns...

I mean, it kind of does that right? Alternator turns full amps to charge batteries, then it goes down to no output. Same amount of fuel/power provided the efficiency is the same at all RPM (im sure it isnt, but probably a negligible amount difference realistically). Essentially, because there...

Have close up photos? So If I wanted to copy (as will use overkill BMS as well). Seems like it advisable just to buy the adapter from bigbattery and toss the 8-wire part. Im looking at 600ah so 6 BMS and 6 adapter add a lot to the bottom line.

Also you can program

thanks guys, I didnt know this.

Sorry am more concerned with the lead wire adapter piece. Someone else here is trying to find what works with this battery so you dont have to splice in wires...and not bigbattery is out of these. Thank you!

@Opie91 is this theory or can you point to supporting documentation? Is it for lifepo4 specific (not lithium ion?). What kind of life reduction is expected when you keep topped off at all times? Thx.

@traderd65 could you take a couple close ups of the 8-wire BMS adapter?

@Sails there is also a alternator protection device availabe in the $70 range - can get from Battleborn. Eliminates size/weight/fill with water of LA battery in parallel.

FYI you can grab that APD from battleborn w/free shipping for $74 I think

Theres also the EVE Cells from @Craig but unsure when another order.

what kind of load can these take for charge/discharge? 24V 100ah - is 1C or 2C able or even more??

Why does this matter?
