Hey Guys, I have staff that won't iphone out an iphone app to check the charge. That is not going to happen. They need something on the dash like a zenogy battery monitor. Have you wired one of those up?

Nice video, well done. However I have a question, in the busbar configuration could I further reduce the current differences by adjusting the cable lengths for two of the batteries, say battery 1 and 2, to take into account the current path length through the busbar?

Thanks for this. What if you added a couple inches to the battery 1 cables? Would that even it out even more?

Could you have the cable for the inverter in the middle of the three cables on the busbar coming from the batteries? In other words could you connect the inverter to the middle lug on the busbar? Pause at 10:50 on the video

Can these be used as a second battery for a car?

Ok so will AGM lead be okay like the first set up? For two batteries? My boat has 2 battery system. Factory wired it parallel but battery (1 ) & (2) are 5 ft away from each other. The load is plugged into battery 1 like your first set up. Battery (2) is 5 ft away located in the back of the boat with just the Pos & Neg cable ran to it from battery 1 😅. Neg to neg pos to pos. Long cable. Should i just add a bus bar to it at this point so it pulls from each end? Draining & charging it equally as 1?

Saw Jasonoid's review and I love and want this lid! Is it possible to get with the 275SE? That model is better for me as it is a bit lighter weight. My use would be home backup to recharge my power stations.

Great vid - thanks for posting - what Screen / Case did you use for VenusOS on the RPI ?

What size are you cables?

Great info ! Much appreciated ! Liked/Subscribed ! *FJB !*

I love your video, this is extremely helpful for me as I’m setting up a 8S4P right now. The question is instead of a bus bar if you want them equally distant why don’t you just have one post where they’re all connected together? A single post and stack up all the connections that way they’re all equidistant?

The ground should be at the other end

Why are there so many low grade ( failures) generated in mass production of LFP batteries? Precision manufacturing shouldn’t result in such high losses. This is very concerning.

They look ok, I will gladly accept them for testing and review on the channel,. Best regards, ParagonDIY

Most people don't have a Hydraulic crimper. Many of us are not great with electricity projects. This would have been a much better video if you did it manually. This video is useless.

Does someone know how to weld the thread diy?

Dont buy nothing from china! Lets ban china! They steal and cheat! Alm china products are very bad and fake! Youre paying too much for garbage! Buy usa or eu products!

I prefer eve terminal with flexible bus bar. And using simple screw.

That first battery taking the load more than the others . I hook up the power to one of my battery's and the ground on the other to keep the current and load the same . I do the same with Power Inverter too

The one flaw in your setup is you should have fusing to each battery either at the battery or the busbar connection. Fuse rating at 150% of anticipated load. This prevents failure due to one of the batteries internally shorting and the other batteries delivering 10XC (C = battery capacity) current!! In your setup 60 to 80 amp fuses would be suggested.....

A custom made circular bus bar ? A big flat washer with battery lug holes on the outside and a big hole in the middle for the input/output ? But with just a standard bus bar mount the two anode/cathode wires of the four on top of each other with the charger/load wires in the middle ?...🌩 ⚡️

stupid way of talking

The Ranger can pull up to 400amps under a load. pulling or going uphill. The BMS will shut the cart down.

I'm completely stumped as to why no one is commenting on wire Guage. I'm seeing all kinds of wire used across the internet and no one seems to care but people say it's important... but leave it out of every tutorial. I have 3 12v 200ah batteries to be run in parallel. I was just going run a bolt and nut through the 3 red to the red trunk, and the 3 black to the black trunk. Wouldn't this be better than a bar? I'm stuck on wire size... I'm also stuck on, do i need a fuse and what size to my 3000w inverter. I have a bunch of 8awg and some 4/0. Was going to 8awg the bank and 4/0 the trunk, with a 100a fuse, although i might up it to 200a. Thoughts? In case anyone cares: 2 x 60v 7ish amp solar panels, 300w? To controller run in parallel. So 60v 15a for 600 watts. To meet 100/50 mppt. 3 x 12v 200ah sla bats run in parallel(haven't done this yet, but planning to) on 8 awg wire to stud/ trunk. Trunk would be a fused 4/0 to inverter. All lines would be as close to same length respective to their run. Although I feel like a fuse would mess up one leg on the trunk... something else i don't see anyone addressing. Any help appreciated

The negative wire should go out to inverter from the last battery.

Stack the terminals instead of bus bar?

Great video man!

Does Victron have a 48v system and are you working on a 48v kit?

Question. i got hold of 57 free batteries of 6volt 4,5Ah NiMH type of batterys .. Thats a lot of batteries.. i wish to make a giant powerbank in parallel connection .. Is there something i have to remeber? ... do i need thicker cables then the ones that already are on the batteries? how is it when i charge that many batteries in parallell ? do i need a super charger? or just use a normal charger that will just take much longer time? I also got a hold on 43 of 4 cells NiCd batteries with a voltage of 4,8 and they have 4,5Ah -- planned to make a 2nd powerpack with those. All batteries are only 3 years old and they are fully functional.. they had to be replaced because of strict rules on batteries that feed emergency light on ship .. they get replaced every 3 years even the law say 5 years.. guess shipping company just want to make sure their ok .. they have been maintain charged trough the years they been active.. and they only sometimes get used on test of the emergency light onboard.

I was told that everything goes to One positive bus and 1 negative BusAnd everything is distributed charging equally. In a parallel configuration

Can I buy this switch to go with my SFK 200 amp BMS ?

what type of welding is used to weld to the cells terminals

Very good teac😊

Great video, it helped me figure out why I was having shut downs in my system. Love the buss bar!

Good 👍 stuff..

Don't buy from these people they have the worst customer service.vthey are liars . They have no customer skills. Talk bad about other sellers. But they can't even ship on time to blame it on labels. Can't even now up to their own 0:12 mistakes. Be careful they are not honest business people.

Higher nominal translates into lower value of current at discharge test.

I really want to buy US made. I like ur batteries, but need a nice % off inspiration. All your competitors are doing it. Help us shop US confidently! Thanks!!

You should have used a saw to cut the lug for display. The cutter you used smears the copper, and even a bad crim would look smooth…

Good video. One of the odd ball things I have seen out there is others maintaining the battery to battery connections and doing bus bars.

Thank you much? This was a huge help!

Excellent video, thank you!

What would happen if you tapped off the middle battery.

We were fortunate to have SFK send us an early shipment of eight of these for some customer projects. They are just as great as this video shows. We purchase completed units and received one with a transparent lid for demo purposes. With the transparent lid, it's easy to see how well built they are without taking them apart. This is another terrific product by SFK and I can't wait to see what they have for their next product(s)! No other battery manufacturer in this space innovates as quickly as SFK.

It would be useful to add the multiple mounting option around the whole perimeter on each side of the plastic boxes by adding many threaded inserts. Using angle bracket moutings would then allow the battery to be attached to the floor or wall. And with flat bracket motings, the batteries could be joined together.

This 24V battery looks very cool, but I can't wait for your 48V battery.

I’d watch the “end” of the charge, ie. Final voltage achieved to see if the stock charger was able to top those batteries off.

What about the new flexible busbars for the new two hole terminal? Ordered 16 new a grade eve from an european shop preorder. Two hole terminals come with flexible busbars. Should take out any issue with slightly angled flat surface not making the best contact. Also less stress on the terminals while swelling. But nobody seems to have tested these yet.

I'm just getting into this stuff, so I'm somewhat stumbling around. This is a very useful video. Ij ust got an Elefast 100 Ah Bluetooth-enabled battery. I'm still waiting for a few other components which will arrive soon. The app lets me see the real-time voltages of each cell along with the amp draw for the battery. I'll put some loads on it (up to 100 amps, as high as the BMS allows) to see how the cells respond. If they are crazy, I'll return the battery, but maybe they'll be ok. Having that monitoring that monitors the voltage of each cell will be really useful.

any ideas what the range was after some testing?
