Hi, I have the same battery as the resistor to use antispark, in winter I charge the batteries at home because I don't want to charge in the cold, main bms ant 300a
I have the same BMS in my pack. Just be aware that it can only handle 100-120A Constant. Those cells are nice. I wish I could find some here in Canada for a decent price.
The 300A model? I'm aware of that and even then, the 2 8awg wires couldn't take 300A! The guy I've bought from is the only seller as far as I'm aware and I know he says he only ships to europe. I could ask him but shipping them would be hefty!
Looks like a Rats nest of potential problems with all these wires for a not needed bms setup.Seeing how you have crammed those cells in the frame ill be interested if you intend in riding this build offroad.Im sure it will all work out in the end though.
@Fpvlee A BMS is basically essential with a powerful build like this (look at other people doing a similar thing and you'll see). However with the frame I chose, granted it's a tight fit but when I insulate everything (and I mean everything 😁) and secure it all down, it should work fine. Also I plan to mainly use it on road but who knows where I'll end up going 🤷♀️
@@EverythingEbikeChannel Its not essential on simple builds like these add in the very little space you have .I know a good few builds including both mine that run over double your projected power.Im by no means saying dont use one just they are not essential is all.
Very good job mate I wish I'd have found your video sooner I have the same BMS and cells wired it all now and cased with alloy plates and I forgot to put the temp sensor in the middle of the packs like you have 😩 any advise on a second place to fit 4 temp sensors 😩

Not yet as it's not fully built and probably won't be until the summer. Should be around 55-60mph and 35-55 miles depending on riding? Some of the sensors came with the BMS, and the others are 100kΩ 3D printing sensors bit.ly/3o53xx1
@@EverythingEbikeChannel thanks, dont get why do you need 2 different temp sensor, any reason? Im just trying to fit 72V in the same frame but need to cut the frame somehow lol
@@alexferenciYou don't basically. I'm planning to build an arduino based module that reads data from the bike and then displays it on an lcd. Probably could have used the same sensor and then soldered an extra pair of wires on but didn't want the arduino interfering with the BMS. I know a few people who are fitting 40+ cells into this kind of frame and they've either had to chop the underside off and make a deeper bracket or just cut the frame in half and extend it.
I haven't actually sorted that out yet, but have seen a 40A audio power supply from Connex that I would love to use (has adjustable current, over current protection, voltage adjustment) but at the moment am using my 250W bench power supply. The Ah of the battery doesn't matter what charger you use, it's the maximum charging current you need to find from the datasheet. 👍

@@Kenny-jg8ld They've both got pros and cons. I can't see the samsung cells on battery hookup but I know their specs. Li-ion packs can be made to fit any enclosure as you can spot weld them together pretty much how you like as long as you have the parallel and series connections. However if you look at it from a price perspective, you would need 182 cells to build a pack that's equivalent to the pack I have which (assuming a cheap £2.5 per cell) would cost over £450 for just the cells without nickle strip, spot welding or wires. But the cells I chose do need carful thought for mounting and connecting. If you want more info, I can give you my email address. Great to hear your building your own!
Hey found your channel it’s very good, just keep up the good work. Also if you ever go to a 5000w hub motor think about configuring your battery to 72v will give your bike some extra acceleration
Thanks! I would love to have a 72v pack but I chose range over speed for this bike. With a custom build li-ion pack and larger frame I'm sure I'll do it one day. 8kW is certainly a step up for me though!
You connect the positive of the charger directly to the positive of the battery, and the negative to the same wire from the BMS that goes to the controller. It will detect that current is flowing in reverse and give you all the protection features. Also works great for regen

@@fpvlee1586 Better safe than sorry I guess...
@@EverythingEbikeChannel If you balance charge your packs and treat them correctly you should not need to be sorry lol.Enjoy the build bud
@@fpvlee1586 And that's partly what the BMS is for, along with over current protection. But of course there are lots of ways of doing it 😁👍
When you charge the battery using the ant bms do you have to turn the discharge mosfets off? Or do you leave charge and discharge on at the same?
I leave them off in the app (just turn charge ones on) but I think it will handle that automatically so no need to worry about it.
