 The battery number resistors settings on the aliexpress page were wrong. With a too big resistor it did six flashes on all LEDs.
+===== Configuration =====
+By resistors, can set number of cells to between 2 and 6S.
+S voltage is too high for regulator used on common aliexpress boards.
+Does not balance battery packs.
+Also can config max current.
+Has I2C, but it is on the same pins as the LEDs, so need to choose.
+Can add NTC for battery.
+k, B=3380
+Connect from pin 37 to ground. If not placed, use fixed 10k.
+Stops charging if outside 0C to 45C (wider limits for discharge).
+BAT_MODE pin 46: Open / float LiPo, short LiFePo.
+RVSET = 7.5K for 4.15V charge cutoff.
+Battery Capacity
+Set to allow meter LEDs to work properly.
+===== A battery pack I have =====
+  * 3S, 5P.
+  * Cells: 3.7V, 2200mAh (marked 8.14Wh).
