I've been obsessed with this ever since I was a kid, but never had the direction to know what to study to master electrical circuits without killing myself lol
The first time you charge a battery that was that low can be pretty dangerous. The chances of a cell being unbalanced is a lot higher when they sit for that long. I recommend staying close to the battery for that first charge and being near a window or a door in case you need to throw it outside. Also, be sure to charge it fully so that the bms can enter the balancing phase.
@@bj97301 I know how to check balance and temperature, I just don't expect every single one of the customers to do that. Especially with deep discharge cells that have a way higher chance of forming dendrites on the quickly growing SEI layer. Also pressure can build up but that's not visible in cylindrical cells until the top goes pop.
@@Beeeeeeeeeee got a better idea for where to put all of these batteries? If so feel free to implement it. It’s easy to poke holes in other people’s ideas.
Wish Arrival would produce components for mini busses and perhaps eventually a DIY kit to let builders get the frame and panels to create an electric mini bus. The materials they use to cover their vehicles won’t rust or dent. I believe a lot of people would want it.
Can we get a picture of the MOSFETs on the BMS? Some how I'm doubting the you can string them in series like that... I mean, what's the maximum Gate-to-Source Voltage of the MOSFETs?
Hi Jeju, how did you connect this secondary pack to the vehicle as it's not recommended to connected to seperate battery packs of different size configuration chemistry in parallel or even series in an ev.
As far as balancing, is it just relying on each batterie’s BMS to eventually equalize everything out? I’d be worried at a certain point some packs would start getting down to 30v while others are fully charged. Need a 400v version to add range to a Ford E-Transit…
Jehu, I’m working on a VW beetle conversion. Can you confirm I’m thinking of this right? With a Hyper 9 HV motor rated at max 180v I would need 5 of these packs in a series and 13 in parallel to get about 30kwh? I believe my beetle will get about 4 miles per KWh so that leaves me with a range of about 120 miles. Does that sound right? How would you arrange these??
In your bus are you using the bms from the pack? If you use the BMS do you use the small leads to charge or go through the discharge bigger leads to charge? is there a separate charging circuit?
Please show us a DIY version how to combine 2 of the Bluetti ac200p units together (like u can with AC300) I will buy more batteries and have more inverter capacity if I could combine my two ac200p solar generators.
Hi ju .I have been watching your vids .great vids I see you have a lot more options. Hope you can help want a 72volt 20ah battery for my ebike on my down tube I can use 2 -36 inseries what do you recommend of your inventory...small and lightest as possible. .18or 19"down tube.thanks in advance.
I’ve seen nothing but bad things about them. I’ve seen people open them up and figure out that it’s not actually lipo4 and they supply you with a lipo4 charger (very unsafe) and seen other people have them explode
I'm just learning about battery packs for e-bikes I would like to make up my own packs, I like to make up 52 volt packs ideally to batteries for my e-bike I'm not clear what BMS to get I see something generic BMS's recently priced I don't know if this would be when you're better deals to split apart and makeup to 52 packs being seem to be good quality cells or if you have other options with more capacity and cheaper all in all I'm very cheap thanks for your time let me know if this will be the most logical and cheapest route or if there's another way to get quality sales a little more work the tear apart something
What would you recommend on a battery and voltage for a E300 Scooter i am replacing batteries for and a controller for now. looking to upgrade the motor after i burn up the stock one.
@@JPSURF16 not sure it will fit 3. I see people use 2 for sure. I am getting the 36v R3 hoping the BMS will be a small one at the end. Then I can cut the battery down the middle and make it shorter and wider. Which will be the cheapest. And almost the same ah as 3 hoverboard batteries. Most of these scooter pack they are in 2 rolls of 20cells. But it will be too long to use in razor. But my plan is to change them to 4 rolls of 10. Then they will fit perfectly inside the tray. Also most hoverboard battery come with the cheapest cell and low capacity like 2500 or 2600ah per cell.
Did you decided on you replacement motor and controller yet? Maybe hold out on the battery until you decide. Because those 48v 1800w my1020 brushless motor and controller are cheap and a very popular up grade choice. Same amount of work as the 500-1000w brush motor. All larger motors require to drill new motor mount holes and remove kick stand. If direct replacement the 350w will be the biggest you can go.
I did a 36v over volt on with a 36v controller on the stock 24v motor. It go much faster about 18mph. It is for my 80# kid so the motor is not burning up. But if I am going to ride it for a long distance. I assume the motor will burn out. So keep that in mind.
i wanna buy the 2x untested r5 36V 13AH 460WH pack what do you think the chance is that both of then sont work like 50%of the time they don't work or what?
I am building a scooter with a drag car slick I have a 24-volt Jazzy wheelchair motor wonder what you recommend for a battery for it if you can help please

Yes

@@jeremym9140 damn. I need to open one up. So far I've had 2 10 amp chargers fail and a 5 amp charger fail. Maybe they are different cells
I cant really understand when you said the capacity of the 18650. Was it 1000mah per cell?
On your battery pack shows charging and discharging from the same cable right?
Discharge cable is bidirectional.
Do you see any more motorized wheels in the pike?
Jehu could I add one of the popular 40 cell Panasonic packs to a pack with these and still have it function ok?
Now if you have to charge the heavy cables first, then the smaller cables, how do you do that on your bus?
You only have to do that the first time, after being dormant and not used for long period of time
@@jehugarcia I see, thanks.
So, on an ebike, why not use a simple "Y" connector to run two batteries in parallel?

Correct, tested working unit has no dead cells
I would like to get 100 of those-R5’s…
We have them
Looks like a great battery
Would these packs work to create an add-on pack for a first generation Nissan Leaf?
Battery is battery. You can use these for anything you want, the question is how…. That I don’t know
