    Default Systems Saber, Adjusting low battery indicate for TX and RX

    Adjusting low battery indicate for TX and RX.

    I am converting to lithium Ion batteries across the board. Has anyone adjusted the low battery alert on these radios? Any guidance as to the ADC decimal value versus the actual voltage? All I have gleaned from the manuals is that the reference point is 1/2 the battery voltage. I have already run down one home brew battery until the BMS disconnected the load. Luckily it reset, but I would like to know within 20% or 25% of battery capacity where this will occur. Assuming a 2 cell arrangement it appear the BMS will detect at a voltage of 4.6V (2.3V per cell). I would like to set the alert at 6.8V which would indicate a SOC above 25%.

    So again, what do the ADC decimal values equal in battery voltage?

    Hmm; maybe this is answering my question assuming an 8 bit. 256 count ADC. Seems my default setting 158 is 6.17V. (5.0/256) * 158 = 3.0859, * 2 = 6.17V
