PWR level

 

Hello,

If I use a Windcamp 3 Ah battery, I can choose the power among the values LI, LII, LIII and LIII (blinking). If I turn off the windcamp switch and plug in a 9 Ah Bioenno, I can only choose among LI, LII and LIII. Does it mean that with the Bioenno I can only output?2.5 W?

This only means the voltage (not power) of your Bioenno battery is not high enough to allow 5W output mode.
When a battery voltage is greater than ~ 11.5 volts the 5W output is enabled, when a battery voltage is less than ~ 11.5 volts, the 5W output is disabled. It does nothing with a battery capacity, only with a voltage.

Not quite right. Blinking will only indicate, that voltage is lower, but power will be 5 watts.

Did you try to measure the power?

Following Blasco's advice, today I used a Powerwerx meter:
?
With Bioenno (LIII not blinking but with all 9 bars from PO indicator lit):
RX: 0.35 A, 13.06 V, 4.7 W
TX: 2.3 A, 12.90 V, 29.6 W
?
Screen:
RX: 13.0 V
TX: 12.1 V
?
With Windcamp:
Screen:
RX: 11.0 V
TX: 9.9 V (from this voltage on, the LIII icon was able to blink)
Regardless of blinking, all 9 bars from the PO indicator were lit.
?
The behaviour seems contrary to what Serguei said, but in accordance with what Andy said.

Not really. Blinking indicator means the radio produces 5W, but voltage is less than ~11V. This works with a built-in battery only. With the external battery there is no blinking indicator at all, the 5W output with indicator disappeared or 2.5W with solid three bars only. Therefore you can get 5W with voltage less than ~11V from built-in battery (blinking indicator), but you cannot get 5W from external battery with less than ~11V (no disappeared or blinking indicators, three bars or less only).

You are right. I was mistaken. I thought blinking only works with a built-in battery only. I just checked out, the indicator switches from none to blinking, with external power with a voltage less than ~11.5V.
