Re: bluetooth BMS?

Hello, in one of these bms there's a high-voltage sound alarm when a cell exceeds, say, 3.55v.? (for charging the battery lifepo4).
I found this picture that looks like yes?

Re: Speedict Ebike - Anybody seen/tried this?

Hi, they told me that the 20s? is coming up next month maybe.

I will also use it with this charge (Adjustable Digital DC) CPS-6011 60V 11A Gophert (c.c/c.v).
Will go everything okay?
Now I use it to charge 16s at 80-90%. without bms.

Rear Rim Type 20, Alex DM24 (inside), forward Rim Type 20 , 1,8 inside.

My weight 60kg, bike 19? battery 4 or 13kg. + possible 20kg shop. Some I wanted are no...

Re: Using cheap adjustable power supply to get 80% charge?

I'm satisfied with mine, I don't need various battery chargers anymore. I charger the lifepo4 at 90%, and sometimes check with the test for safety the parallel that increases before the others. When I need 100% sometimes I finish to charge with the balancer charger to 99%, I don't trust a lot of Bms...

Im sure it will put some charge in your batteries, but remember it is only a power suppy ( CV reg ?) and NOT a CC/CV controlled charger.
Most batteries are charged with CC initially (to about 80%).
mine seems to be a CC/CV controlled charger,
charged with CC initially.

11 amps is overkill; not sure many batteries can take that? Usually I charger from 4-7 ah and are batteries lifepo4 48v 30ah (8 years old) and 7,5ah a123, and without bms, but I do examine with the balance charger from time to time, to be more secure of the stability of each 16s. in the future I th...

I don't need it because I use a three-button switch, with 3 different powers and speeds, I start with the delicate only to prevent gear breakage, it's enough for me, and it regulates my pas according to the law, (separately from the throttle). consuming a few extra watts doesn't bother me with a sub...

If the hub you received it semi disassembled, perhaps the cause of the problem could be from incorrect assembly (washer). I opened a bafang, I had the wrong washer position when I assembled it, and did what he's doing to you. I can't remember if the washer was inside the hub or at the freewheel. Aft...
