Not meaning to reply to myself but even my DP242 display acknowledges the 52 volt battery on startup and gives a pretty accurate battery display in percentage. Probably to enable one display fits all voltages across the range.
It would be really really interesting to fit a 48 volt battery to the 43 volt motor ( or even a 43 volt battery to a 36 volt motor ), my M600 48 volt motor will accept without any high voltage warnings a 52 volt battery. It in some ways is a much nicer motor as it lifts the best cadence to about...
Guys, please be aware of basic electrical calculations,
V x A = Watts which is what you feel as power from your motor.
Whr's is simply the Watts x hours which in our case is the energy contained in your battery, that has nothing to do with the power of the motor.
So if Amps were to be equal
36...
For the amount of time involved, far simpler to buy a late analogue bike which seem to be going for next to nothing and enjoy riding a more modern analogue bike with all the trimmings, late Geo and swapping in the goods bits off your Cove as and when you need them. Old frames really are now...
There are other simple things to look for as well, a number of people have found that they haven't inserted the connectors to a full depth, they look right but can be inserted with an extra push another few mm making a full contact.
I have seen also a couple of batteries with poor welding...
Its very easy and cost effctive to put a very small magnetic switch on the brake lever, there's quite a lot of detail on this over on the bafang thread on EndlessSphere.
Sounds more like your battery BMS is cutting out, you may want to check your wiring connections or that the BMS can actually carry that amount of current if you have DIYed your own battery.
Be aware that the higher current cells voltage can sag badly in the later stages of discharge. This as we have found from actual use will trigger either the battery BMS, the bikes low voltage threshold detect or simply will mean the motor will go into reduced Watts output, much earlier than an...
Ummm where do I start, we don’t use Lipo batteries, we use Li-ion. I think you are maybe confusing the advertised nominal charge capacity and max continuous current.
If we take the Samsung 21700 50E battery you have a 0.5C charge rate (2500mAH ), a nominal capacity of 4900 mAh ( 1C ) and the...
I would largely agree however in the world of practicality and production cost you are not going to produce a new design of cell with 0.001gm lighter materials just for the Bafang M820. Instead the cell manufacturers are going to stick with their production line where they make millions of...
Not quite, good battery build will ensure that interconnections will handle any load between cells.
You can get some cells that will handle the 20A load as a 1P design but and it’s a very big but, you will trade capacity Wh’s for instant Amps. The best and most suited cells for EBikes are those...
Just looked online and the Shimano M8000 is all 11spd ( which I have on my EZesty ) and I know I bought 3 x 10spd cassettes as part of a deal about 18 months ago ( on my last one now ) which I thought was M8000, but apparently not.
OK so the only 10spd Shimano I can now see available is the...
Sadly an 8spd rear cassette ( Acolyte ) just has too wider spacing for a good feel to the shift. But that really depends on what rear min and max rear cassette teeth you want. I tried the Suntour 11-46 8spd but it really felt notchy as in a large jump between gears. If you were only interested...
Look on EBay and the likes and the 2 smallest gears are available seperately.

And change your chain at 2/3rds worn, you can increase the life of the other gears.
