Absolutely, it should not be done on a regular basis even though the BMS and controller do a great job at protecting the battery. I wonder if not reaching 4.2V per cell but 54.1V total is also done for longevity.

It should use the full voltage of 54.6 unless it's done on purpose by the bms to prolong the lifespan.

As for the opposite question, my charger just showed the green light so the charging has stopped, however the battery is only at 54.1V. What's happening here?

I think on DasKit displays you can't change that. At least on the L7 one.

I don't think that with 4A charge on a >13Ah battery you're in the danger zone. it's not even to close to 1C.

15A controller for sure. Also would a 48V controller handle a cut off voltage for a 52V battery?

Yes DasKit, doesn't the controller handle only current though? So you would only get slight more power because of higher voltage?

Still have to see if you can even use that high voltage with the controller?

Don't know, I don't even know what brand is used inside the original batter pack 😅

No it's the Dorado case. The problem with these is what kind of cells they use? I doubt NCM chemistry.

Yeah sorry my bad, I meant 720W. I see, the ones sold in the EU have a 15A controller that you can unlock since it comes shipped at around 10A. I forgot that in the US the limits are different. It's rated at 250W but you can unlock it to 350W nominal.

Are you talking about the NCM bikes? I thought the controller was limited to 750W @ 15A. Did you pay import duties?

I tried today to fully discharge it and when I tested the voltage when the motor turned off it said 40.5V and when not used for a while it will still output a little power for a minute. So I would say the cutoff voltage is around 40V.

On this site https://www.leoncycle.com.au/dehawk-i5-battery-48v-for-ncm-moscow-milano-venice I see 42V cutoff, isn't this a litte too conservative? That is 3.23 per cell. But then on this other site https://www.leoncycle.com/replacement-battery-for-ncm-moscow-aspen I see "End Voltage 27,5V"...

Does anyone know what is the cut off voltage of the standard Moscow's controller?

Sure I don't think that would be a problem. I haven't used my bike lately so my main issue now is to decide which brakes to get.

The weird thing about the Julet connector on the Moscow non Plus in that is not that list. I really don't know where they got that 2 pin connector from. Seems like they're the only one using it.

That's what I thought! Thanks! Is there maybe a list with names of all the types of Julet connectors?

I see, I actually never thought about it before (funny because I own an EV with NMC batteries and read a lot about them :D). I thought it was some kind of German acronym :p NCM does of course features this lithium batteries...

Hey thanks, mine has a 2 pin Julet. Comparing with your picture it seems the Aliexpress item has the same plug. Don't you think? However when I find the 2-pin version it doesn't look like my 2-pin Julet. mine https://electricbikereview.com/forums/attachments/img_20201023_090538-jpg.69465/...
