Cool update as always. Speaking about super/ultra capacitors. I've deployed a bunch of Davis Instruments weather stations; very reliable, but to one caveat is those darn CR123 batteries needs to be replaced every year or two. The locations where they've been deployed are sometimes take me an hour or two of drive time to get there to service them. Upon discovering that they use those type of capacitors, I let my www fingers do the searching and found a supplier that sold them direct to consumers with a minimum quantity at a reasonable price. I purchased a 100 Farad radial lead version that was small enough to fit inside of the unit. From my unscientific testing, a fully charged 100 Farad capacitor can keep the transmitter unit up and running for up to 5 days if the onboard solar module failed. Although highly unlikely. Now, I don't even bother to install the CR123 backup battery; there is onboard remote telemetry monitoring that will alert me if there is a power issue. What I like about the super/ultra capacitor technology is that I am able to have my weather monitoring stations almost to completely autonomous for 5+ years. Now, I just need wait for the prices to come down so I am able to do the same thing to the logging stations reliably. Cheers...

Awesome way to utilize the technology. For use cases like this, capacitors are to me, clearly the way to go.

My CR123A batteries are used in the ARLO camera. I hooked up 8 (2s4p) 18650 EBL batteries and instead of changing them every 3 months, they should last for a couple years. My brother had a rat trap that took a D, I fixed it with a 26650 EBL and a spacer battery made out of aluminum foil and duct tape.

Yep, I did the week and a half burn-in test on 2 more weather station transmitters. Working on the 100 Farad mod today. Then another 2 more weeks of burn-in time and out to the field it goes. The bad and the ugly part is that I just voided my warranty. :-( In the end, it is still worth it...

There is a saying on the net, that "it's not truly yours until you void the warranty". I agree in the end, it's still worth it.

like the video! I am looking to put something together for our future home. Wanted to ask when you installed your Ultra-Cap bank, how did you determine what size to install?
Sorry I forgot what are the size of you caps? Thanks for showing

My ultra caps are Maxwell 2.7v 3000F each x 12 in series. It's their K2 Series BCAP3000.

Your ultra caps does not really help for constant loads because the battery bank still is labouring very hard to charge the ultra caps. With sudden load spikes, it will do the job very well by smoothing out the current spikes. Load spikes, like the fridge motor goes on suddenly. the current draw goes high with the sudden start of inductive loads. Thus your capacitors will protect your batteries from these load spikes.

Do you have a video on installing the caps?
