Re: bluetooth BMS?

Appreciate your feedback. All the cells go up correctly from 1s to 10s in approx 3.8V increments from b-0 as they should up to 38V. The last cell 10 is 38V and the second wire from b+ to power the mother board is the same 38V. I think you may be talking about a different BMS board related to the led...

Re: bluetooth BMS?

Took a little break from this as I was irritated with it-but now I'm back. My battery is 10s. Total 38.6 V currently. Approx 3.8 V per cell. Today, I opened the battery back up. Also took the cover off the BMS again. The 10th jst pin location shows a red led light on the board. (Photo attached below...

Re: bluetooth BMS?

Well truly massive disappointment today. Ran the balance mode yesterday to balance the cells and everything worked great. Balance mode worked to within .01V as set on VBMS app. All VBMS info showing up on my phone nicely. Getting psyched to charge and go for a ride. I went to charge the battery and ...

Re: Shock absorption AND cooling ?

You could put some plastic over the bottom then use spray foam on that to get a surface which could then be cut flat or as needed. Then you could pad that with whatever. As an alternative solution for others, I would suggest that a battery bag with some give and a foam wrapped battery inside provide...

Re: bluetooth BMS?

Turn on the BMS by holding the small momentary micro switch down (if you have connected it) or shorting the two small switch wires to each other for 3 seconds then disconnect them. This turns on the BMS. Make sure both red led lights are turned on to show the BMS is working and the Bluetooth module ...

Re: bluetooth BMS?

The VBMS does all voltage set point adjustments, alarms, controls and more to manage your battery. Look up VBMS on the google play store. There is an overview there. Looks like it also coordinates with gps, etc. but I havnt got into that part. Thanks for pointing out the importance of putting the al...

Re: Where to Get Clear Shrink Wrap for LiPo

Next challenge. Went to extend the factory presoldered wire coming off the BMS so I could have 2 seperate longer negative leads coming off the C- pad. One for charge and one for discharge as shown for the single C- pad method (in other words both charge/discharge leads connected to the C- pad only)....

Have a cargo bike and I'm looking for an original version 1 or 2 kickstand from Extracycle. This version is really wide and goes into the side of the extracycle footpeg holder to make it very stable. They don't make this version any more. Anybody have one on a shelf somewhere? I'm in northern virgin...

Bought this Stokemonkey motor used to put on my cargo bike but I never needed it as I went with the cyclone kit instead. Prolly worth around 400.00 as is?

Girvin, noleen, proflex front fork

Comes with shock. I was going to put it on my cargo bike but the stem isnt the right size. Bummer cause this is a cool front fork.
Will ship.
250.00 seems like what they are going for?
Will take offers and ship at your cost.

Re: Battery and BMS are not wired properly?

OK, so I pulled all the sense wires off the battery and started to rewire it. Interestingly, I tested the BMS with a multimeter and found the B- was already coming from the negative of the battery and so no b- for the sense wires needed. Ran 11 sense wires to the pluses for each cell and then back t...
