    You might want to look at something like an Adafruit Feather M0 instead of the Arduino Nano. It has a much more capable processor (32-bit ARM Cortex M0) and can still be programmed in the Arduino...

    Charger is probably seeing an open circuit as the BMS is not closing the charge safety relay.

    Vacuum forming a clear tank sounds interesting. I vacuum formed an ABS tank and it showed the rough spots in my mold. Now I'm making a better mold and back at it.

    Should be a fun build. Why are you trading the AC-15? Going for a 20 or fit issues?

    I see digikey has the iso1050evm for $49US which could be a cheap solution for isolated CAN or you can get the chip and some parts and build your own but it will cost more with your labor added.

    I couldn't see any markings on the screen to indicate what timebase you were set on. The controller should output 0-300Hz drive frequency. If your timebase is set to 10ms per division you should...

    I used one of these solid state relays on the charger port to let the BMS shutoff charge current. The charger sees the current drop to zero and shuts down....

    The LEM CT is a good choice. Curtis should be around 300Hz (well within the LEM range 0-20kHz) and the datasheet mentions pulse width modulated. Looks like you get an analog waveform output so you...

    You are right...purpose made IC's like the ones from LT or Freescale would be better. Celllogs are ready made and give you a record of use that is very handy. I started with resistors and an ADC...

    Sounds like you would use 25 resistors (~8.30 Euros) and one ADC (~$15 US https://www.adafruit.com/product/1085) connected to an arduino or ($11) STM32 Nucleo board which gives you a charge timer and...

    Good catch Tom! The 10-bit adc on the Atmega line can handle up to 5Vdc directly for one cell, beyond that you need help to get the resolution you need and/or an isolation scheme. You could use an...

    Sweet! Good application of RFID. This will be a nice improvement and will be more secure than an ignition switch if you protect the wiring well. Range is so short that false triggers shouldn't be...

    I use a Vicor VI-24P-EV DC to DC because it has a pull down enable that floats around 13V so it can work through the stock key on your bike without putting out of range voltages on it. It also can...

    The Pi zero seems to contain unobtainium, unless you got one on the first day, and has no native audio out. I'd look at the A+ to get reasonable power consumption. (If you want better audio quality...

    If I was starting today I would choose Leaf modules over the LiFePO4 cells I have now, saving money, weight and space. Thinking about converting but still have too much life in these to justify it.
