I have a question that I think might be related to this Post...I want to be able to turn off my inverter but my WFCO panel is full and the converter is already on a shared breaker... As of right now when I cut the converter off I lose power to several of my outlets. Can I not just add a single...

I can’t seem to get my battery charged over 80% I think I’ve got some parameters set up incorrectly... can I get some quick thoughts from folks...

Very nice. Where did you get the braided bus bars? I think that is a critical piece of the puzzle...nice job...

That seems about right... mine went for over four days before I started getting movement ...don’t leave them un supervised...

Exactly...I watched this thing like a hawk....Its tempting to raise the voltage...Don't do it !...

A short balancing countdown video I made a few minutes ago. After slow charging for almost 4 days, the amperage is starting to click down, and the battery voltage is starting to go up. Went from 3.37 to 3.55 in under 90 minutes. It's all coming together... Balancing Countdown LiFePo

Thanks....moved them properly...I totally forgot out that...

Plugging away...

Yep...I've got an RV and will eventually have to update the converter/charger in the WFCO panel - so that it can handle a LiFePo profile and is more compatible.

I wish I would have a purchased a bigger power supply now...I got a 10 amp CV/CC to do balancing not realizing how slow this same charger would be to use to just "charge". My EV cells were all sitting at around 3.2 when I got them...now it's taking me forever using the 10amp. The TekPower...

I"m doing single cell topping now with a 10 amp CV/CC power supply. Mainly because I want to see for myself what the visual ques' are from the power supply and get a feel for the process. Like someone above, I only have a 4S setup. So my plan is get all the cells near 3.5...then rack then...

I decided against a B2B for now - The distance from my F250 alternator to the battery bank in my towed 26ft RV will end up being almost 40 feet. Using the Victron Cable Calculator, for a 30 amp charge, I would need to run 1/0 cable....I cannot visualize this being a good option yet. It makes...

I'm getting a quote now from Mac Metal. As it turns out, their on-line website was just "turned on". Nice folks and I talked to them today...

Good deal...I have a copper pipe in the garage...about to smash !

I'm short of bus bars at the moment... and have a 4S Configuration. Q - What's the downside to me top balancing each cell one at a time rather than all 4 at once? I'll just hook up my power supply to each until they find the top, then move to the next... Not a crisis...but I was hoping to get...

Robert470 - LOL...I feel your pain. I've not ordered yet but we might all be splitting hairs here...If I get the M6 option, I'm going to go with two 4AWG wires that I'll fabricate and cut to length for my install...

Awesome...does it come with 3 M6's on each side, or with 2 like the photo shows (might be an old photo)?

I don't have much to offer other than to say thank you to everyone that is giving input on this question. This board is really my go-to source for finding out cutting edge techniques to solve my solar challenges. I wanted to tackle the DIY LiFePo for the same reason that I wanted to put brakes...

Has anyone purchased an Overkill BMS with the "Stud" option ? I am assuming it has studs instead of the 8 or 10 AWG leads? If you have one, can you post a picture...I'm trying to decide what options to get.... Edit - I did see a photo on his web site and it only has (2) studs on each side...so...

If you connected this to your 8735, can you explain / show how you did so...? tom

Wow...this is really helpful...there are a lot of 8735's out there...I too called WFCO and asked the question...I called tech support, not sales...they told me the same but said it would only charge to 80% - said a new 8735Lis was coming out for Lithium... Anyway, thank you for posting all of...

I talked to the WFCO manufacture last week. There is a new WFCO8735Lis coming out - it is designed to charge LiFePo batteries...apparently the standard 8735 does not do so... check out the website for WFCO... www.wfcoelectronics.com

This is all very interesting. I'm doing the exact same thing - with the exact same WFCO 8735P Power Center. I am finding out that this Power Center is not set up to charge Lithium cells. I talked to the manufacture yesterday. They have a new model that is coming out very soon...8735Lis is the...
