Running iPad Mini 4 Without Battery


I’m after some advise. I’m using an iPad Mini 4 Lte as project, I need to run it without a battery as it’s being used in car dash. I will hard wire a power supply.

I’ve done this with various tablets in the past by using the battery circuits board then running 5v power supply from an USB Charger.

Ive tried the same with this iPad Mini 4 LTE and no joy.

Without the battery, using just the old battery circuit board. You get no power, if you use lightning cable it just does the Apple Logo loop or the battery charging icon.

Any help without trying to fool the battery circuit board in thinking there is battery connected? like removing diodes, resistors. etc

I’ve attached pictures of the iPad logicboard, and the battery circuit board.
