Won't boot on battery

[-=Sp00k=-]

Just got my new Tetra.  It will not boot on either the Pineapple juice 4000 or the big one that I ordered with the Tetra.  I tried both the uart and the eth1 ports.  Works just fine with the AC adapter.  Of course I did the usual... factory reset...  nope.  Default firmware... nope.  Upgrade back to 2.6.2... nope.  Different Y-cable... nope.  regular USB3 cable and nope!  Endless yellow to flashing blue loop.

Any suggestions? Perhaps an RMA?

did you find a solution ?

The WiFi Pineapple TETRA requires 24W for normal stable operation. See the power considerations article at https://docs.hak5.org/hc/en-us/articles/360010471754-Power-Considerations

While it can be operated from USB power, it would require both USB ports to be supplied 12W each (2.4A USB port) from either a single or two separate batteries to achieve this.

Thank you Darren...  The addition of a second battery fixed it!

Here is a possible suggestion https://www.bioennopower.com/collections/12v-series-lifepo4-batteries/products/12v-3ah-lfp-battery-black-w-pvc-pack

These batteries are used in Amateur Radio.  My question for Darren is whether the Tetra can take 14 volts which is what these batteries do when fresh.  The battery will produce better than 12 volts for its entire ampere hour rating.  They also can function for thousands of fully discharge cycles, effectively lasting forever.   Modifying the cable from the wall wart with anderson power poles (or some other DC connector) would also be needed.
