Bro ur knowledge of how to do this stuff is pretty incredible
Id really really consider sorting that soldering out not only in the qs connector but on the copper strip also run the cable all the way down on the negative side like you did on the positive side under hard discharge you may get uneven discharge
Also maybe some ffp sheet to protect the battery
Just my 2cents
Man you are an inspiration ... thank you
Good shit bro just had my ant bms fail on me waiting on replacement 96v 100ah
You need a 150 - 200W soldering iron for those 4AWG wires and flux.
Hmm yeah mine is definitely not that!
I found the best way was to put the wires on before spot welding them to the pack You can use a minni blow torch and large solder works heaps well, like how they coper solder hot watter plumbing
Do you have a link to the BMS and the QS10?

Clean build. Very nice
I really really like how detailed this video was… also my second batter build is going to be a very big build 28s 20p using jp40 cells ( also if yo haven’t heard about them read up my boy lol ) but do have a question have you tested the amperage and what did you end up with ( and yes I know you have the BMS controlling the amps)
The battery can do up to 945 amps.
Now If your talking amp hours thats 88.2Ah.
Are you talking about the Ampace jp40?
if so i have indeed never heard about those lol
Im going to have to research up on these!
@@ItsMalliea lot of people havent heard about them lol so if you hadn’t heard about them I wanted to make sure you did causethey are very very good cells and can push a lot of amps… but 945 is crazy… I’m also shooting for around 900 peak and around 500 continuous… good luck out there
@@2facedTony Yessir!
The project that this went to needed some power!!
amazing battery but damn how are you soldering those wires😭😭😭😭
Yeah it bad! lol that's the one thing i feel like i still really struggle with.
@@ItsMallie do you use flux?
@@foebelboo Tried to use some to spread the solder a bit... i just suck at soldering thats all lol
@ItsMallie preheat the wires with one of those torch lighters they sell to crack heads at the gas station. Then use your soldering iron to finish.
Can you put the list of the material in the description? For example I am interested into the connector. Thanks.
Good idea!
Very nice battery build. Your soldering needs work. The iron isn't hot enough or you should let it absorb more heat. When the solder is hot enough it'll flow through those wires rather than just sit there. The soldering on the connector also same issue. You might have wanted to do a technique where you fill the connector with the solder then heat it up and insert the wire.
Also with such a high voltage and high amp discharge. You may need to prechargre the caps in the controller.
Overall very nice build can't wait to see the project and what bike your putting this on
Yeah my soldering really sucks lol
But if its because of not enough heat like your saying its probably the very cheap soldering gun that i have isn't able to get hot enough
so definitely gonna get a better one in the future.
But when you ay pre charge the controller caps
what does that mean? never heard that before.
flux flux flux
I think he means because if the caps are not pre charged in the controller it could be a crazy spark trying to put those connectors together @@ItsMallie
@@Truebillycat Ooooh ok i think i've heard of that.
Well that isn't necessary due to the QS Connectors, They are anti spark connectors so plugging this in i get no spark!
hey bud! what copper is that .1 or .2? beautiful build
.1
dare i even ask how much you spent on cells getting good cells in the uk is a nightmare nice build bro especially for your 2nd
to get the amount of cells i got right now would be 2499 but not including shipping
I have ordered p42a and lishen 2170la cells to the UK, just as cheap as they get it in America. cant make that excuse man.
where did you get the cells?
LiionWholesale.com. i'll put info on everything else in the desc soon
cooling?
Well... that will be determined by how i build the project that will be using this battery, But it is going to be air cooled either way
What is the kWh?
10.3kWh Fully charged 8.8kWh Nominal
Hey hope all is well…. I wanted to ask have you tested this pack for its amperage ( with or without the BMS) I’m asking because I had these copper nickel busbars that I won’t be able to use. So I may have to go copper/nickel sandwich strips like you. But I want to make sure .1 copper will be able to handle 900/1000 amps( and can’t find any charts or info online ) so like did you achieve that with this set up?
Not quite.
The bike that this battery went to is so strong that it scares the 💩 out of me to pin the throttle therefor i don't think i've ever went high enough to get to those amps but with the little bit i did do and how long i've had the battery for it gives me no issues nor does it overheat in anyway.
