Re: Develop a QCA7000 board?

Around 90mA at 13V. This is a lot of heat for just doing nothing, we should look to possibilities to safe some current. I see 5V low iq SMPS and 3V3 LDO, one option is put uC controlled P-fet switch on 3V3_D line to shut QCA completely. This could be tested by removing R43. QCA datasheet seems to r...

Re: BMW i4 battery 84 kWh

This is interesting and bit dangerous design, as there are no separate BMS boards on every battery module, here every battery cell wiring is connected to one big BMS module. Module isolation for measurement is done on BMS board. This is kind of hazard, because those are low voltage connectors and if...

Looking for Tesla LR pack or equal

Looking for big capacity battery with good SOH and preferably 96S. Tesla 3/Y long range pack or modules would be pretty perfect. Perhaps 108S could be possible option too.

I tried with Mitsubishi charger, but it measure input voltage and was not happy with DC I bet it would be just fine with non-sine supply, even bit dirty H-bridge 50Hz might be just fine.
