Yes it's stable at 25A, that's the same current as bbs02 stock controller. I run mine at 52V 30A, as long as I don't push the throttle for too long it doesn't overheat, I use it mostly with pedal assist. As for the fase connectors I bought the correct connectors and a crimping tool from a...

I'm running a BBS02B with BBSHD controller, can confirm that picture is correct, it fits and you need to change the bullet motor fase connectors.

First Thank you @mspider65 for your brilliant work in this project! Just to report, with an Android 11 phone I can't update the firmware, app just closes when I press the button to start updating. I used another phone with Android 10 to update the firmware, it went fine. Today is raining I...

Yes, tested with full battery 58.8V, it works. With stock firmware my controller didn't accept more than 56V.

I flashed this firmware posted by Tomblarom: CRR10E4830E105027.1_(latest)_190927.bin Can confirm it works with 52V battery, has a current limit of 30A, and corrected the issue of PAS overriding throttle. Thank you Tomblarom for sharing this firmware!

Yes, it's a controller's firmware limitation, bafang introduced a 52V/28A and a 48V/30A in the latest years. There is an older 48V/30A firmware with higher overvoltage cut-off that works with 48V and 52V batteries. If you are willing to take the risk, you can flash a firmware from this thread ...

Looks like you are making some confusion between capacity, measured with Ah(Ampere hour) and voltage measured in volts (V). Em3ev consider each cell do have a capacity of 3.4Ah, if you multiply this value with the number of cells in parallel it gives the total package capacity of 23.8Ah. In...

In your eggrider battery settings try a lower value for voltage 0%, for a 14s battery it should be around 42V (3V per cell). I'm not sure if your battery percentage is wrong because of that, because I don't have an eggrider, but is worth a try!

Looks like INR21700-48G is a Samsung cell https://lygte-info.dk/review/batteries2012/Samsung%20INR21700-48G%204800mAh%20(Gray)%20UK.html It's a good priced pack if cells are legit, but I would not trust someone who calls Panasonic-Tesla a Samsung cell.

wow that was fast [emoji57], thank you! I'll test ride it this weekend.

Already see that this is a bug with 2.1.2 and 2.1.3 Android app. With Android app 2.1.1 I was able to introduce the correct values for Battery cell overvoltage, it should be around 4.2V or 420 mV x 10, but with latest App it is out of the range, looks like it is expecting a overvoltage value for...

Hi! I installed this PCB today, running with last firmware (esp32 v1.1.2 and controller v7) and android app v2.1.3 I have 48v motor and 48v battery (13s5p). I can´t set Battery cell overvoltage and Battery cell all bars, it does not save the values that i input in the app, it revert to mutch...

You are right, sorry about that! I will remove my posts to avoid confusion.
