E-bikes newbie question

[d8veh]

I think you need to slow down a little bit. There's lots of different ways to get to where you want. You need to understand how they work and what's involved before deciding what to do. From some of the questions you're asking, it seems that you're missing some knowledge. Do you have any soldering experience? Do you know how a BMS works? Do you know about charging procedures for lithium batteries.

The LCD is plug-and-play. I'm 90% certain it will release you speed limit, but it won't give you more power. The 48v controller doesn't cost much, so it makes sense to get it at the same time to save postage. You'll be able to learn about changing to 48v later, and see which is the best way to get it. The options are: Change to a complete 48v battery, the same type as you already have; chuck the battery (at least the cell-pack) and replace with 12S lipos; modify your battery to increase it to 48v by adding in extra cells and changing the BMS; use a separate booster pack in series with your 36v battery.

The 48v controller should be a direct swap, but it won't work with your 36v battery.

I think you need to slow down a little bit... 48v controller should be a direct swap, but it won't work with your 36v battery....

.. but for the sake of experimentation, why not put that over-amped controller on, with a 36V battery, and a 250 watt motor, and just to add excitement, wire it up with 36 gauge wire... :lol:

I am already so slow it will take a month for the items to arrive, I have some soldering experience yes, English is one of my issues, I aint sure what is BMS.

Do you know about charging procedures for lithium batteries.

With the IMAX B6 i guess there are some videos otherwise I don't think so, my battery is 10 cells to make it 48v i have to add 3 cells multiplied by 4, 12 batteries. but the issue that I wont be able to charge it with my 42v charger if you have ideas please share them.
I have no idea how to crack the limits from the LCD or the controller, I can open them and upload pictures if you want them, and I am so please that you're helping me

I don't see this getting better since the OP obviously will not listen. My advise stands. Start over with all the right parts, but I guess it's to late. One positive. He'll have a bunch of stuff to cook.

We tried.... all we can do. I'm sure my dad had similar frustration as I was growing-up with my head screwed on side-ways. Sometimes its the school of hard-knocks that delivers the lessons. Oh, experiments and experience. Can't wait to put my MXUS 3000 on the road at 50 amps and 60 volts. Thinking of putting that setup on a $100 aluminium frame from Walmart. :lol: :lol: ... no, not really. Hopefully the OP will continue to post his experience ... I seek the forum for laughs, not just advise.

if you have paid more than 1200$ in less than 3 months you'll know that it is so late to start over and in the shitty country I am living at if you miss a 1 battery it takes you a whole new month to get one, not mentioning a whole new kit costs more than 200$ for shipping only...

I got no body here to share me same interests people only looking at it as a waste of money "bikes" and I am trying to learn from Internet but I have some English understanding issues.
I see trying and experimenting is the best way to learn.

 

[bahaa.zahika]

could any one tell me how i would be able to charge the battery when I make it 48 Volts without buying a new charger ?
and does the bypass the speed limits ?

Its never too late to put together a working eBike the right way. I've spent more than that $1200 USD learning the hard-way in the school of hard-knocks. Wished I had found and followed ES-forum advise before that.

Well, no... the best learning takes place with reading-up, then trying things based on your best understanding. Fail, go back to reading & asking questions of experts, then try again with an improved approach. Until you get it right.

Your battery has a 10 cell management system (BMS) that prevents you from damaging it by over-charging or over-discharging. If you add another three cells, it can't manage them, so you have to get a 13 cell BMS or manage the 3 cells by yourself, which you can do with a imax charger and a real-time voltmeter or lpo alarm.

Does your bike already have a LCD? I didn't see one in your photo.

SorryI meant that:

From where I could get a 13 cell BMS ? and what is over-discharging ?
charging them by imax that mean I have to open the battery case each time :|

 

[bahaa.zahika]

I have space for 16 Samsung batteries thought.
is this the BMS you're talking about ?
