I see the spec has been changed to 6v now. It used to be higher.... I wouldn't call it a spec. 6v applied to V_BATT should be viewed as a maximum value. Damage will occur if V_BATT exceeds 6v. V_ROBOBATT maximum becomes a thermal issue that depends on the V_BATT load you present to the robostix... --- Ken |
