The older DP242 display used to give accurate % right down to 1% for the 52 volts, the newer DP245 doesn't for some reason. On my M510 it works out about a display of 40% is around the 46 volt shut off ( which is 3.2 volts a cell, the motor knows you started with a 52 volt battery ). On the...
Be careful with what appears a very limited knowledge of batteries. Can I suggest perhaps doing quite a bit of research into battery building before proceding down this route. Little things like parallel charging with approx. voltages can lead to some serious problems. Choosing the wrong cell...
Does the display register the correct speed when spinning the rear wheel on a stand. I think the motor has to see speed registered to continue supplying drive ?
Thanks for the reply Dado. This high cutoff is stopping me using nearly 100Wh of a 800Wh battery. In 3 years the battery technology will have moved on so far that my 800Wh battery will be redundant. How many Ebikes batteries are going to be charged 1000 times a year ( typical cells are based on...
I've had a bit of a realisation that the M510 controllers at 52 volts know that it is a 52 volt battery and will shut off the motor at 46 volts on the battery even without any CAN signals ( home built battery ). Thats 3.2 volts a cell. My old M600 motor used to run the battery fully down to...
Sounds very
Sounds very much like a connector problem, check the usual culprits of the display connectors not being pushed in far enough and down at the motor end, also make sure the connectors are pushed firmly into the correct place.
Voltage levels changing could also be the battery to...
This guy might be the guy to ask. Bit further on than the French / Spanish border but maybe worth the extra couple of hours driving.

For every rider who hates the over run there are an equal number who ride technical trails that like it. I think your perception that " everyone" hates over run maybe a bit flawed.
In my case I have learnt to use it to advantage and can now climb up over extended rough steep uphill short bursts...
Thanks. Yes looked at his mods and from my engineering experience, its a good mod but.
I've just pulled my M600 engine down and largely for the really harsh environment of the UK winters where I'm riding in wet, muddy, sandy, rock strewn conditions for possibly 6 months of the year, for the 3K...
Not actually sure as I bought it in and stuck it on the shelf as a spare as I had eyesight problems with the older DPC242, I'll have a look in the next couple of days.
I think Neeko had a vid of it but I can only find the short clip Quick Peak of the DZ41 display (CANBus) hooked up to the...
Mike, you maybe better looking over on Bafang M500/M600 thread where there are a couple of very knowledgable guys on there ( CiDi for one ) who have already logged the CAN signals. They may be able to save you considerable time.
There are number of replacement screens, have a look at 20.55￡ 45%...
Guys be a little careful with seeing 42 volts on a voltmeter. Although there is volts on the line, there may not be enough current flow ( power ) to be able to power up any of the motor processors to begin the power up routine ( which includes powering the display.
You may need to put some...
It was missing for a while but now back on the EBay site.
Not sure about the L but I think when I bought my E10 there wa sonly medium available, they slowly bought on the other sizes over about 6 months.
Note the size of batteries ?
