[@jasonhamilton5756]

I have to agree with the placement up front. It will let you easily see it, and if you ever have to remove the pack you don't have too worry about removing the lead. It makes the unit a self contained thing. If you where worried about getting glue or something on the board, use some clear shrink tube on the board so that you are sticking the tube to the runner and not the actual BMS board it self.

Hello there I use xt60(Amass) connector with cover on back on every pack....they are rated up to 60A and look really good all insulated.... Looking good new busbars👍

[@dtec30]

I think for reliability and visual indication put them on the front will also be a reminder too when you go to remove the packs for any reason to disconnect the mon board otherwise on the side you may forget it and pull the wires

[@cheetahkid]

On the front think best, so you can see the LED. Did you find out the maximum current of those batteries together? Not sure it will cope on that copper wires.

[@kurtpalmer3674]

I'd put the long Mon on the side (between the busbars) and could you use large spade terminals to join the packs and if the spade terminals don't have the current carrying capacity you want you could place the bus bar is a x pattern with a join were they cross in the middle and then have 4 spade terminals one at each corner I'd also use heat shrink or some other insulator between the last solder join and the terminal to join to the next pack :-)

[@Dutch_off_grid_homesteading]

The front mate if one fails it would be much harder to get it out to replace it. I do not know how many strands you used but I am thinking of using number 10 multiy strand wire on my next ones I do

[@Diy-For-Life]

So which is better. Im building up for 14s100p to start. Im curious is there any electrical benefit to running say multiple banks of 14s10p. I get there would be little less wiring going bigger. But i want the packs to serviceable. Being able to remove smaller packs for spot testing and hot swap easier. Im thinking larger packs make for harder to change that one bad cell in the center of a 100p or eventually like to be talking 400p and larger.

[@TheUserid82]

You can build a simple wire stripper using a 2x4 with a hole just large enough for the wire and a drywall screw into the side of the hole just deep enough for the point to cut the insulation. Can be done to cut the larger bundles and individual wires as making a hole and a drywall screw per size is easy and cheap. For bundle wire holes 2 smaller sized holes drilled together work well for flatter bundle wires then a large single hole with room for the wire to move around. A C-clamp to mount it to the table and you just pull the wire to cut it and can peal it ether as you pull or after with no strain on the wire. When stripping the wires a bucket or trash can to pull the wire across lets you collect the insulation as it is separated to reduce repeat work.

The BB looks a bit flimsy where it joins at the lug. I would solder 75mm of the ends of that twisted wire to increase stiffness.

[@HBPowerwall]

It is very flimsy however this was just a test fitment to work it all out. Ones I'm making at the moment are twice as thick :)

[@SidneyCritic]

If you solder the ends for a distance it becomes a rod, so it might be solid enough as is. The individual wire strands can slide on each other, where as if they were soldered together it would become a rod with a greater 2nd moment, thereby more rigid.

[@TechMan-sl5gf]

I’ve been watching you for a couple of weeks mate when I ran around this method. Am not sure if it will met my main needs of powering half of the houses that uses we will say on worse time of year 40kw. But it does have other possibilities that am thinking of. Your design is clean and practical unlike some of the of ones I have looked at. I do have some disagreements but haven’t yet came up with the answers myself so I can’t fault you there. I’ll cover that in a bit. The use of strained wire is better because it can carry the amperage better. As I think you know, the current rides on the outside of the wire and not through it; so it’s better for that. It should have the same surface area as what you did before but much easier in the construction. Here is what I think I would do. I know you made the jig on the fly but I think I would use trim wood to help bend the wires near the correct shape. You may need some claps of sorts to keep the wire locked into position as you formed its layout. But if may not be worth it as you maybe nearing the end of your build I think. For myself am just going to run two wire from the centre positions of the left rows and right rows and not wrap it around at the base as you did. I don’t see the point or gain in doing this; electrically speaking. I will keep it in place using clear silicone sealant. Now, this is the bit I haven’t liked on any ones design and I haven’t solved it myself. It’s the the way each bank is connected together. No matter if it is horizontal or vertical and I have seen both. It would be better for safety sake if it wasn’t bolted together. I see all kind of chances of dropped bits getting between and shorting out the lot. When these batteries do explode its a mess. I saw another bloke that used a vertical shelf but kept it negative to negative or positive to positive on the shelve so it reduces that possibility. But giving the housing I think heat will be it’s overall problem verses your design. What I would like to come up with is where it would connect to some automotive style connector which the wires go to the other bank using the same connector to plug into it. The problem is it’s not very tidy even through its more safety minded. I guess it could be hidden under a plate which is what am thinking about as I write this. But I’ve been trying to think of something that it could plug into which may not be practical. If I could then it wouldn’t be a powerwall but a power cube that would sit on the floor with indicator LEDs on the sides where if there is a problem you would remove the fault module and replace it with another one. Then I would have the same problem as am looking at if I use a forklift battery which is what am also considering. Loss of floor space but much more lighter. The problem for that design is the battery pack temperature. So, temp sensors would have to be added to enable fans to blow it out. Since the power will have to come from the packs then there would be a loss of power to run that. Thinking about a power cube design it would have to have some sort of power management. Not that BMS nonsense I keep seeing for bikes and what-not that charges each cell. But to look at each module for performance issues (voltage and current) and temperature. If any of the packs were bad then it would disable all modules in that given array to prevent damage to the rest and the fore mentioned explosions. Then just replace the pack and reset it so it will re-enable the module array. Either way it would have to have a super structure build to house all of the packs and manage the cooling of it. Now, let me say why I have been thinking about this. There are a number of people around the world working the next generation batteries. There is one bloke in the UK that has increased the storage of a battery. All of the ones I have looked at are using graphene or graphene oxide. In all of the claims as it hasn’t been fully fielded really is that a battery the size of 18650 could be increased to be 3.7v @ 185A. Now, I don’t believe that amperage but even if its four to six times greater then it makes this something I need to look at more seriously. Now, these cells are really supercaps in battery style housings as it’s not really charging it chemically but statically. So, if it can store say 3.7v @ 20A then it’s something I need to seriously look at.

[@MrSummitville]

Who told you that stranded wire carries the DC amperage better? You need to educate yourself before posting such nonsense. RE: BMS - clearly, you have no idea what a LongMon is or does ...

[@MrLabarr123]

hi love your set up quick questions 1st how many amps is one pack and voltage. 2nd is total of each square 36-48volt and total amps

[@MrSummitville]

How many (max) AMPS per your cell ? Then multiply by # of cells per pack. Voltage = all cells are in parallel.

[@richardhoard5951]

My vote is for putting it on the front. Putting it on the side of the pack makes me a bit uncomfortable. Did you know, you can make those end terminals out of copper tubing. Cut, flatten one end and drill out the mounting hole. You are then only limited to the available tubing sizes. You don't get the purdy plating on them, but then you have enough exposed copper in your system.

[@HBPowerwall]

[@markjamieson2005]

using that smaller cable made testing so much harder the 10mm cable would have sat and bent into position so much easier also are you going to heat shrink the copper at the terminal end? as for the pcb, visible IMO as you'll be able to use the flir to check it easier

[@MrSummitville]

3 twisted is 1/2 the price...

[@rhoemberg1969]

Spin a line of solder into your wire before you form the buss bar and then heat the buss bar to melt the solder into place in the form it will stay rigid then when fusing across you can just wrap and heat the cross connects .

[@HBPowerwall]

That's not such a bad idea!

[@MrSummitville]

@@HBPowerwall Don't you think it better to twist ONLY the copper conductors first and then apply soldering iron (heat) and then slide down the wire with solder? Copper is a much better conductor than solder.

nearly impossible to say. I had 10 identical looking battery packs with identical specs and there were 3 different brands of cells between them, Samsung, LG and Panasonic. I guess the production dates were different. The grey ones are panasonic cells, and probably the 2900mAh ones. The OPUS BT-C3100 he uses to test the cells shows about 10-15% more mAh then it really is, so those cells are about 2550-2700mAh in real life. I have quite a few of the same cells testing 3000mAh in the same charger.

[@SoGladUCame]

Can any battery nerds answer this for me. I have some lifepo4 18650, they all are externally metal (originally wrapped in plastic that is removed), and all but the very top is negative. So, you can just sit them next to each other side by side with no risk of a short, as it's all negative on the outside. I'm thinking instead of welding all the bottoms together for the negative connection, that I would just let all the bare metal cylinders touch which is a lot of surface area actually, and then just heat shrink them tight. So, would not need to do all that tab welding or soldering of wires on the negative side anyway. As I don't like how if 1 cell would die I would have to desolder all that mess just to find the bad cell. I could just remove the heat shrink and seperate the the cells with card board then test them individually. This would only be done for the parallel battery blocks of course. Anyway, guess the question is, is there anything special about the bottom of the cell that makes it a better location for the negatives to be attached, like is it thicker, or something. These cells were reclaimed from a bad 12 volt battery used for a medical device, so I already had to "detab them' once, and in that process ruined some of them, but like 2/3rd were good and I have sever of the bigger 12volt batteries, so will be making my own 24 volt battery from the cells. THANSK!!!!!!!!!

[@MrSummitville]

No, you can NOT just heat shrink the entire pack together - that is NOT an electric connection. And when a cell fails - you just cut that cell out the pack and re-insert a new cell.

Here is one of those tips of a lifetime for stripping wire! Get a piece of preferably some hardwood (oak) about 2in.wide X 4-6in long. Drill a hole just slightly bigger than your wire in the piece of wood then drill another pilot hole perpindicular to that hole on the opposite side of the piece of wood! This is a pilot hole for a woodscrew that you screw into the piece just so it sticks into the original hole for the wire about 1/32in. start your wire through the hole about 2 ft. then pull . The screw point will cut the insulation. adjust the screw as neccesary so the wire doesnt bind up when you pull it!

Also with the chemistry all mixed up and of unknown ages balancing is going to be a problem and you will need more expensive high amp balancers to keep up with it. Some advice for those who are thinking of doing this, but I like the project and you have a lot of power there to manage, it's like your own power company.
