Hi Frank from Aussie great video from start to end no B.S all good info.........Enjoyed and subscribed

Looks like it will work fine, please do a follow up video showing installing them.

Nice mod on the busbars! I buy "excess" power wires, which often are too short... this is the solution. thanks!

Got a question on your BMS if you got a minute? Are you attaching your leads to the first battery of the parallel battery? Or are you going to +/- of each battery? The later is what I was thinking was how a normal way to connect an BMS.

Amazing as usual ! Wow Frank, your videos are so awesome. How do you it?

Frank, why wouldn't you hold the sections together and solder them together instead of crimping? It would be fairly quick with a torch and solder. I think you should be good but it would ensure you have a solid electrical connection between segments that isn't susceptible to oxidation.

Interesting Idea!👍

How many amps can the inverter that you will use with these packs draw? Is it a 12 volt inverter, so 4s40p packs at 12 volts X 3 in parallel or are you building a 36 volt battery with 3 X 12 volt packs in series?

what would 2 10 gauge wire be equal to. about 7 ga? I'm planning to connect them to a small 1/0-2/0 buss. with 0ga. to the inverter. 5' long. with the cable connected in center. so it is like doubled. the cells will be connected to opposite ends. then to the buss.

I soldered my 10 ga with a 150watt iron. . maybe you could solder yours also?

What the heck happened to your thumb?!? Oh, excellent video too!

hi why use busbars?

great work, just getting started, would like a copy of your spread sheet to keep a complete record, but the only address i found so far did not work. Could not find a download link on thediyengineer.com . Again thank you for your explanations of different configurations for the purpose of the pack and the vidion on the charging board.

I used 10 gauge solid wire. and made a loop of sorts. so its doubled 10 gauge. and I have average Joe glass fuses. I haven't actually assembled anything yet. but I don't like them. its 40 cell packs . all paralleled. then the packs get wired 7s. I'm planning on 100-120a max peak current. for now until I get more cells. my cells will do 5a continuous. but I hope to get the peak current down to 100ma eventually. that will take lots of cells. I haven't done the maths. 225-250 amps divided by .100 amps. eq. lots of 18650's my 5kw inverter plus a few amps for DC loads. about 10a or so. my bank needs to be more of a cube. than a flat.. I'm wondering about the purity of the copper . I never had copper change so many colors when heated to solder. blue purple maroon . its cheap wire from amazon. great video. between my lead acid T-105 . and adding the lithium cells. hopefully I can at least go 8-10 hours without running the generator. and I'm getting solar panels. soon. but that will only charge at under 30a. so I need to build a tracker. I'm thinking about a a small tracking system of 600 to 700 watts. and put the rest on the roof. or ground mounted. then I can at least get the most from some of the panels. I'd like to have the whole array track. but I don't see that happening. what charge controller are you going to use? I'd like to get a flex max. but I'm using a epever tracer. and thinking about getting a Esmart3, when I get more panels. sorry I'm rambling again. I hope to get about 500ah more battery. and to about 2500w in solar. this summer. I'll have nearly 1000ah then. I know it would take forever to charge 1000 ah with 2500 in solar . while using power also. I'm working on a gas powered 150 amp generator. to make up for sunless days and heavy use. I mostly just run a fridge and a freezer and a TV. with an occasionally microwave and 7amp well pump. keep at it.
