 p.1 #2 · p.1 #2 · Running off 12V Battery: Studio strobes and power draw | |
I converted my Elinchrom Quadra Ranger 400W/s packs from SLA to LiFePO4 back in 2017. I'm able to do multiple pops and the battery seems to keep up without much problem with the older Quadra packs. But the newer ELB 400 pack does not like the conversion and will shut down in similar situations. At the time I also bought a LiFePO4 battery from the same manufacturer that was designed as a vehicle battery capable of supplying the necessary current for significant power surges (like when starting a vehicle). The manufacturer thought that for my applications this battery would be the better option, but unfortunately their smallest model was still too large to fit inside the SLA battery box for the Quadra system. So I never ended up using the deep surge battery... In a quick search of their site I didn't see this 'deep draw' type of battery listed, but all of their battery specs list maximum continuous discharge current as well as maximum peak pulse current (and duration).
This is the LiFePO4 supplier I used: Bioenno 12V LiFePO4. When I was researching options for the Quadra LiFePO4 conversion I had questions and contacted them for advice. They were very responsive and helpful, so it could be worthwhile contacting them to explain what you would like to do for their feedback.
What is likely also important is an inverter that generates a proper continuous sine wave. Given your Einstein strobes, you could go with the Paul C Buff Vagabond Mini battery/inverter system. I use a couple with two Einsteins and the strobes work flawlessly, though recycling time is double that of plugging them in the wall. Buff used to make a heavier duty LiFePO4 based battery/inverter but discontinued it a while back. There might be info online about using the Vagabond Mini with Profoto and other strobe brands. Buff touches on this briefly in their FAQs and suggests you contact them with your make/model of strobes for compatibility advice.
