| The battery number resistors settings on the aliexpress page were wrong. With a too big resistor it did six flashes on all LEDs. | 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. | ||
| + | 6S 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. | ||
| + | 10k, 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. | ||

| + | * 3S, 5P. | ||
| + | * Cells: 3.7V, 2200mAh (marked 8.14Wh). | ||
