VenVolt™ 802.3at PoE+ Site Survey Battery Pack

Charging and Operations Guide

The VenVolt™ is an 802.3af/at compliant during Site Surveys. It can be battery for powering WiFi Access Points

operated either on its back (with the ethernet ports facing the right side of the unit) or on its side (with the ethernet

ports facing up). It supports ethernet pass-through for conguring devices or other ethernet IP connectivity

requirements you may think of (Meraki Cloud, gateway checking, iPerf, etc.). This Charging and Operations Guide will

familiarize you with the VenVolt’s features so you can be up-and-running in no time.

Performance: The VenVolt delivers over 6 hours of continuous run time using a fully powered Cisco 3802, with both

radios turned up to the max, 1 client associated to each radio, both sending trac to each other and to the AP. This is

expected to be a ‘worst case’ scenario, and any deviation from this is likely to produce run time improvements.

Display Gauge: The gauge on front the front cap is not a ‘battery charge’ gauge, but rather a ‘power output’ gauge.

Ventev recommends using the Voltage display when charging your VenVolt. Use the ‘Display Cycle’ button below

the gauge to change the display from Percentage to Voltage numbers for a better understanding of the charge

status.

Note: The gauge has three positions: Voltage, Percentage, and Blank. Simply press the ‘Display Cycle’ button

repeatedly to cycle through the various displays.



Charging: Charge your VenVolt before use. Charging typically takes 4-5 hours to recharge a fully discharged

battery. Ensure the wall charger is fully and securely plugged into the VenVolt’s charge port. When plugged in, and

at full capacity, the gauge should reect the maximum voltage of your AC adapter, indicating that the battery has

completed charging and the voltage from the charger is being fully passed through. Full charge capacity is either

just over 15V (for 15V chargers) or just over 18V (for 18V chargers). Both AC chargers/adapters are functionally

equivalent and fully interchangeable. The 15V or 18V readings indicate that the battery is ‘topped o’ and at 100%

capacity. When the charger is disconnected, the gauge will immediately drop to 13.4V (or so) to show available

voltage. 



Operation: The voltage gauge will oat around 12V-13V during most of the day while in use. VenVolt follows a very

long discharge curve, then drops o dramatically (as indicated by the chart on the back of the unit). This rapid drop-

o is simply a characteristic of the LiFePo4 battery chemistry.

 Normally, no more than a half-hour of useful power remains when volts start to fall o below 11V or so. This

should happen very late in the day during site surveys.

 The VenVolt supports charging while being used. This means that you can simply roll up to an AC outlet, plug the

VenVolt in while it’s being used and it will take a trickle charge to keep your battery up!

 At full capacity (noted above at a jump to 18.6V (or so), the VenVolt will shut o the injector to protect itself from

overcharging. Stated dierently, if you run the VenVolt plugged in, and powering an AP at the tippy-top of its

voltage curve, you run the risk of powering o your AP. If your battery discharge indicator is at 13.4V (or so), don’t

bother plugging it in to keep it topped o.
