Thanks for the suggestion - I sent a quick email to Battle Born Batteries <info@battlebornbatteries.com> and had a response within 2 hours... and their recommendation is the following: "You would want 2 strings of 4 batteries wired in series, and then parallel the 2 strings together." Thank...

No problem. My question was vague. All I have to go on is this statement from battery university which states: With Li-ion, the parallel strings are always made first; the completed parallel units are then placed in series. Li-ion is a voltage based system that lends itself well for parallel...

If I had 8 battleborn 12v 100ah, to get to 48v 200ah, what is the best way to wore these?

Got that. Thank you. I guess I should be more specific. Is it best to parallel 2 first and then series each set of 2? Or create 2 48v strings first and then parallel the 2 strings? Thanks!

Are you doing 120/ 120 split phase for 240? I am planning a very similar set up. I was going do diy sinopoly prismatic for batteries but since I am new to this I think I’ll just spend the little extra and do battleborn. The big question is what are you running off of this and for how long can...

Thanks, I realize that the question about usage is subjective, and I need to correctly calculate my loads, but it always helps to get a read on some real life situations, if I am going to load in to a full system for 10-15k (Canadian) then I need some assurances lol. Regarding the Battleborns...

Will very cool set-up. I am designing something very similar currently using the LV5048 as well, Post here: http://www.diysolarforum.com/index.php?threads/lifepo4-12v-100ah-lithium-iron-phosphate-battery-pack.509/ but I have a lot of indecision regarding my battery bank and to parallel first or...

Thank you Svetz for your valuable information, much appreciated! Regarding your comment about 2 BMS's. I'm a little perplexed about BMS set ups and paralleling them. 1) If I am 2p16s (I hope my terminology is correct - I mean 2 cells parallel to create 200Ah and then series each group to get...

Thanks b.james for your reply! Still trying to wrap my head around best set ups and whether or not to bite the bullet and get all my batteries at once. Seems like the best bet for longevity.

Looking at building a potentially expandable 48 volt LiFePO4 100Ah Lithium Iron Phosphate Battery Pack. I'd like to start with buying this 4X12v kit and series connecting this kit in series to create 100 aH 48 volt bank...

I see that you are still using the Smart BMS in your set-up (one of the earlier BMS's that you profiled in your 48v back-up system video with low temp cut-off). Still working ok? Wondering why you are preferring the newer app connected BMS over this one. Keep up the great work BTW

Thank you for those tear down shots. I hope these batteries work as somewhat advertised even with less capacity. I will say that the poor quality soldering on the BMS and abundant messy use of glue and caulking makes it look like a middle school shop project. I would bet that those are used...

I am in the middle of working with the same supplier for four damaged cells that arrived recently. Out of 16 that arrived, four were badly damaged. I can say that their packaging has certainly not improved. At first glance the cells have adequate padding however the boxes are poorly put...
