    80a bms with 200a controller

    Yeah the fan is a bit louder than I’d like, and moves quite a bit more air than I expected. I cut the hole for the fan to be the same diameter as the fan like you are talking about but the seat bracket blocks a lot of the air flow🤦🏼‍♂️ my plan to remedy this is to build a carbon fiber cover for...

    80a bms with 200a controller

    Thanks for the tip, that’s a great idea. After I cooked my old motor and the magnets fell out I tried to fix it but it seemed to be lagging in power so I threw it away and bought a new one.

    80a bms with 200a controller

    That’s a great idea. I will do that when I get around to working on that bike again. I was able to test the 72v bike with the 200a controller this wknd and the new controller made a huge difference in power, right up until the the bms trips. So it’s time for a new battery now. I modified the...

    80a bms with 200a controller

    Ok great. I’ve done some diagnostic stuff on the bike that doesn’t work but my results were inconclusive, I’ve replaced just about everything except the hub motor so I’m hoping that’s the issue, these bikes are definitely money pits for me but I really enjoy riding them. I started...

    80a bms with 200a controller

    Im located up in Prescott Valley, so about an hour from Phoenix. I actually have a second enduro e bike that I’m stumped on what’s wrong with it and could use some help getting it goin again, you seem quite knowledgeable about this stuff and I’ve had zero luck finding anyone in my local area...

    80a bms with 200a controller

    sorry about the typo, I was supposed to say “higher quality battery” 🤦🏼‍♂️ Thanks again for all the great information. I would like to get a quote for a high quality battery with EV grade cells but I don’t even know where to look for something like that, or what I should expect to pay. Is...

    80a bms with 200a controller

    Ok, what would you do? Risk it with a the custom built 200a bms China battery or try to find a higher quicker battery? From what I gather, worst case senario would be the cells aren’t up to par and catch fire

    80a bms with 200a controller

    I asked about the battery cell info with the battery manufacturer and they sent me this pic of the cells they will use. Can anyone tell me if these are good quality cells and will work well for my intended purpose?

    80a bms with 200a controller

    Ok great. It looks like I should be in pretty good shape with the 200a controller/bms, thanks for running the info through the simulation for me🙂

    80a bms with 200a controller

    How would I go about doing that? If I did so and found that I need more than 200a of power would there be sufficient options that are reasonably affordable (less than 3k) Or would I be better off ditching the enduro e bike platform and move to something like a sur ron that uses a mid drive...

    80a bms with 200a controller

    That’s a great point, I messaged the seller to ask about this information hopefully they can provide it for me. If not, do you know of a good source to get a 200a 72v battery that uses suitable construction materials?

    80a bms with 200a controller

    I got a quote for a 72v 40ah custom battery with 200a bms for the Amazon seller I bought the controller from. They said the battery would be $1700 shipped. Is that a good price? And how do I know if the cells are high enough quality? Is there any other information I should be asking for from the...

    80a bms with 200a controller

    Again thank you for the very informative reply. I messaged the seller of the sabvaton 200a controller I just bought to see if I can adjust it to work with my 80a bms until I figure out what to do about a battery…. They are also quoting me for a new battery but they are in China so the...

    80a bms with 200a controller

    Wow, thank you for the in depth reply. That was exactly what I was looking for. I already bought the 200a controller so I’ll be looking into a battery upgrade next. I don’t have any information on the battery because I bought the bike used, but it looks to be a 72v 20ah and it’s a few years old...

    80a bms with 200a controller

    I Belice it’s a 72v 20ah with 80a bms. Is there a way to upgrade the bms to 200+a so that when I install the new 200a controller everything will match and be an ideal setup?

    80a bms with 200a controller

    Hi guys. I’m new here and have had a 72v enduro e bike for over a year now. I recently blew the 100a controller that came with the bike and have upgraded to a 200a. However my battery bms is only 80a I believe, is there a way to upgrade the bms to 200a to get the full power potential? And are...
