    Battery mod thread

    Yes for sure. It it was not working, either you would get a "not genuine batt" message or the motors would not rotate.

    B0B : Battery without BMS ;-)

    No just a simple resistor bridge to lower the tension in the range of the PIC vdd (8.4 v --> 3.3V). Only the voltage is measured.

    B0B : Battery without BMS ;-)

    It took me some time but at the end I get a very simple option to flight any 2S battery , boot the MM directly on this batt and get some basic telemetry (voltage and an estimate of % of charge). To use it you need to: - keep the firmware <= 1.0.400 - set the batt type to 0 (firmware 1.0.500...

    Have a look here ;-) ... B0B is born https://www.facebook.com/groups/DjiModsMM/permalink/709141743166163/

    Mavic Mini White Balance

    To fix this white skin effect, it's just a matter of exposure, try to shoot with -0.3EV or even more and the face will darken..

    MM LED Light

    Well, I did this for night flying my MM. It does a pretty good job for few grams... https://www.thingiverse.com/thing:4203545

    Mavic Mini BatMan V2 ( a battery manager)

    It was my intention to do so: - boot the MM on the original DJI batt BMS (only the SMbus/I2C part) - unplug the BMS SMBus lines - plug a homemade "BMSlight" board emulating the exchanges However this is somewhat more complex that expected. - the protocol is SMBus not I2C, and some checksum...

    Mavic Mini BatMan

    Thanks for this idea, it is implemented in the V2 device. It drains around 370mA at 8v to push 500mA at 5V into the smartphone.

    Done ;-) See my other post on the BatManV2 !

    Mavic Mini BatMan V2 ( a battery manager)

    the BMS has some internal FET that act like fuses if it detects an undervoltage on a cell or an unblalenced batt or overcurrent it opens the FETs permanently. Those FET can be reset using an encrypted protocol... (SHA algo) but the key is not public. I'm afraid the firmware will follow the same...

    Yes, I know this. But it is not clear, at least to me, if the BMS is coming from an original battery or not ?

    Mavic Mini BatMan V2 ( a battery manager)

    I'm not sure it would work... Part of the exchanges between the ESC board and the BMS over the SBS protocol are manufacturer fields that are not diocumented...

    Get power out of the mavic mini for attachment ( LED )

    No that's not possible... However for your needs you can do something like this : https://www.thingiverse.com/thing:4203545 Have a look to all pictures...

    Mavic Mini BatMan V2 ( a battery manager)

    BatMan V2 is coming... As some of you requested, I added a battery hibernation function to empty the batt down to 65% of charge. In order to keep the device as "green" as possible, the load is either a smartphone or a powerbank and the extra energy is transferred to the connected device The...

    good idea, that would even save some energy ;-)
