Ideally your USB Port should be able to deliver 500mAof current or more. 500mA is sufficient for intermittent use at maximum operation current and charging, you may find thatheavy continuous use will not allow you to take on extra charging with a minimal current USB port.While long USB cables are handy for moving the iVA into harder to reach places. Low quality USB cables can reduce thepower available to charge the iVA.The iVA will self-limit at 1.2A, and is designed to charge from a number of different sources. A heavy use pattern mayrequire the use of the supplied USB Charger.The supplied USB charger and small USB cable is recommended for charging.1.7.2 Charging After the Battery has Been Run FlatThe iVA has a number of protection systems to reduce the chance of battery damage from complete discharge. The iVAhardware will prevent higher current charging of a discharged battery. If discharged, it is necessary to charge the iVA whileswitched off initially for at least 1 Hour. Note : That if the iVA has an adequate charge level remaining, normal and highercharge rates can occur and normal use can commence immediately once connected for charging, lower current USBcharge sources may not support continuous heavy usage.If the iVA is not going to be used for a significant time and has been run flat, it is recommended to give the iVA at least anhours charge before storing. Li ion batteries can self-discharge at a rate of approximately 1% per month, if not used formany months a periodic recharge may be needed.1.7.3 Charging TimeCharging time will depend on the USB port current capacity. A new iVA, switched off for charging with the supplied a 5V1.2A charger can reach fully charged in approximately 3.5 Hrs.1.7.4 Battery LifeFully charged with continuous return loss sweeps and under Bluetooth control the iVA will last typically 3 Hrs of use. Withconnect and disconnect time, rigging and installation work time a nominal 8Hr work shift is readily achieved.1.7.5 SafetyAny attempt to replace the internal battery could damage the unit. Care should be taken to not expose the battery to hightemperatures and to not overcharge the battery. |
