I have 48v capacitor, I'd like to incorporate into my 48v acid battery bank. Has anyone used a capacitor with lead acid batteries? I'm not familiar to capacitor use.
Thanks
To your point - YES supercapacitors are a fantastic compliment to lead-acid batteries because a sufficient bank of them allows prevents voltage sag on the DC bus when a surge load hits. Your capacitor bank needs a voltage rating high enough to handle the most possible voltage your DC bus could ever see, like when equalizing, or else the magic smoke or worse will be unleashed. (Mine can handle 24*2.7V = 64.8V)
Pictured below is what my bank looks like, and here's a link to a pre-charge/discharge circuit I put together to mitigate the problems working with supercapacitor banks:
Recently a bank of 24 Nesscap 3500F Supercapacitors was added to my system to assist with DC ripple and surge loads. Although a big investment, their performance and the preservation of battery longevity they provide is worth it, in my opinion. These capacitors will easily pass 1500 Amps and...
