You will probably struggle to find a BMS with a higher balance current, diybms and batrium seem to have the highest loads at the moment. Somewhere between 0.6A and 2A
Hi, I've no plans to move away from resistor based load balancing - it works for 18650 cells, what do you use?
This could be a useful enhancement for the BMS, and not that difficult to achieve. The BMS would need to have a new "start up" sequence or feature added.
If you are only drawing a watt or two during the pre-charge, then any suitable relay could be used, you would just extend the duration of the pre-charge depending on...
Hi @robanderson, yes the solution is just to let them do the holes.
Oh dear, this isn't going to be easy. The prototype v 4.3 board uses an external crystal rather than the internal oscillator. Therefore the fuses on the attiny chip are...
The XTAL pins (2 and 3) are connected to the SENSOR1 connector - so its likely easier to connect the crystal to this point (pins 1 and 3) You may...
Silly question, but you did provide power to the board via the ISP programmer? Did the GREEN led light up when attempting to program to board?
I'm struggling for any other solutions for you I'm afraid.
Thanks for the useful recovery guide. The new ESP32 controller board does indeed have a built in ISP programmer to help avoid these problems.
