Bioenno Solar Setup

My understanding is that the lithiums don't like cold temperatures...

 

This will sound like a dumb question--but can you run the panels AND the battery at the same time? I was told by someone at HRO that you can't transmit off the battery with the panel charging it. So what then--use two batteries and switch back and forth?

 

Using the setup I posted earlier thats not a issue, battery just keeps getting topped off as you discharge it, the controller in fact keeps track of amps used and amps put back as well as charge amps ...

 

Legit question. I don't know. Please ask Kevin and let us know.

I asked about doing that with the charger and here's their reply:

Hi,

May I charge my 20ah, 12v LiFePo with the 4A wall charger at the same time that I’m using the battery to power a transceiver?

 

At (-) 4F it looks like LiFePo is down to about 70%. If you apply a resistive load and warm it up gently, the outside air temperature won't have as great an effect. Lead acid appears to do worse...but read the links and draw your own conclusions.

Hello Craig. I liked your video and your QRZ page. We are like minded in many ways. I also have a stable of Yaesu equipment.
Take care Hiram.

You left out the fact that your Lead Acid can only be recharged about 500 times. Whereas these can be recharged more than 2000. In addition, These lose about the same charge in a year that the lead acid lose in a month. I just can't picture you lugging around a 300 Ah lead acid battery. My first experience with these were in my motorcycle. It performed so well that over the three years I kept my bike, it paid for itself in performance & reliability, not to mention not having to connect a Battery Tender to it every winter. Nothing like rolling the bike out in the spring and having it fire up on the third crank.

 

Any reason for only running 70 W with this set up? I have a similar set up and run out 100 W. Just curious.

 

Mainly to reduce current draw down some to extend battery run time, the difference between 100w and 70w is very little on the receive end anyway.
