    Bosch 4a Charger for performance and active lines

    I bought a replacement battery second hand and it came with a charger, so I now have two. Offers please, it is on ebay also.

    Bosch Battery/Charger issue

    Well that couldn't have gone worse. INSAT organised package pickup as they know couriers who carry lithium batteries (INSAT told me this) and are insured (I assumed). Battery picked up and damaged/stolen/lost by UPS somewhere along the way, turned up at INSAT as a empty tube with just the...

    EggRider for Bafang BBS01, BBS02, BBSHD

    I'm going to try it anyway, the lack of the plug in power assist level buttons was my only reservation. Perhaps I'll figure out voice commands over the traffic noise. With a Android 7 phablet/phone it will now be possible to run this display and a GPS map side by side on the same display.

    Bosch Speed Sensor

    Agreed sort of. I assume when you switch on the display it sends a signal to the battery pack to turn on and it's not. However how can this situation only occur after a power off due to inactivity and only after a few hours will it return to normal. If my wife remembers to turn off properly, no...

    Bosch Speed Sensor

    It appears when (sometimes) you switch on the display it doesn't tell the battery pack to turn on, which in previous Haibike I've had certainly should be the case, again though it's not all the time. I can fix by pressing the on button on the main battery pack, but this is not right.

    Bosch Speed Sensor

    So nothing wrong with the battery, seems like when you switch on, the battery is not switched on, so the display acts just like its off the bike, I have to actually switch on the battery when this happens to fix it until I turn it off next time. Makes no sense.

    Bosch Speed Sensor

    OK, not random. It appears after much grilling, on arriving at pubs, display is left on and it times out after perhaps 5 minutes (someone should know) and shuts down. when going back to the bike, she turns it on in the normal way and although there is power, no mph display and no operations on...

    Bosch Speed Sensor

    As you say, it's not aligned to the bolt, alignment is fine. Anyway it works most of the time and only breaks when switched off. Actually come to think of it I wonder if the missus is actually switching off or perhaps the issue is when it turns off itself after inactivity. I shall enquire...

    Bosch Speed Sensor

    Random speed sensor working, not working on an active system. Stop at pub, get back on, no speed, no errors, nothing and of course no assist, pedal home leave overnight and working again. Doesn't stop or start working unless system is turned off and on again (not windows 10) but not every...

    Bosch Battery/Charger issue

    Well the motor is an "active" which is gen2? So how can you tell for the battery pack? Also some of the balance wires are disconnected/melted, but (and I'm not sure) these are read only by the BMS, the main voltage supply is still connected.

    Bosch Battery/Charger issue

    Just reading similar stuff online regarding "suicide" tamper chips in Bosch powerpacks since 2014. Mine is probably post this, but close to this date being an active model. The microprocessor certainly gets readings x 10 for every 4 cells to check accumulated voltage is even. Cannot get the...

    Nothing on their website suggesting battery repair, are you suggesting contacting directly.

    Bosch Battery/Charger issue

    All options are welcome, but there is a discrepancy between the bars on the battery and the LCD display. Unfortunately as the pins are so close together on the accumulative voltage returns on testing, I shorted across two and melted the wires. This makes it way more tricky to fix. Nothing...

    Bosch Battery/Charger issue

    I have had many electric 36v bicycles and all are 42v chargers, that actually includes Bosch's own battery powered mower, currently charging at 41.8v. On top of this whatever the charger and battery is indicating, the intuvia display states 4/5 on the the power levels and range is not what it...

    Bosch Battery/Charger issue

    Small update - the fifth battery light does go solid eventually, but individual cells / overall voltage remain 3.92 / 39.1 respectively.

    Bosch Battery/Charger issue

    Won't seem to charge past 39v. All cells I can reach with the multimeter read 3.89v, but I cannot read the accumulative voltages, the pins are just too small for the multimeter. Also, although the incoming voltage from the charger also reads 39v, there is a third pin to/from the charger, so DC...
