Or a good metal box. Or polycarbonate to see. clamp it down and then no worries maybe
Or a different approach and put in the bottom of a hobby store rocket.
I found and lost a paper on the web that was doing 6c,5c…and w temp sensors n claimed 5c was acceptable as it kept within the maker specs. But didn’t see what specific ion cell they were using. The easy fun way to find the answers is a test. the 30q. Hope u do.
Be nice if u charge w a meter to measure the in-going capacity recording from some set low soc to 4.0 and then discharging on a board as u normally would immediately. And maybe just an infrared temp at each rising volt.
The power supply will be a lot (ill link one) but worth charging the whole board so you can discharge it and it’s practical, and see how the cells heat each other while charging.
Id rather fast charge to even a low voltage and not even bother going past maybe 60% charge if i could do it with great speed and still maybe even this would have greater all around safety and the cells lasted more cycles and kept their capacity. maybe. maybe the heat produced would be ideal for the cells as apposed to their typical cold state when charging
But it sounds like you can have your cake and eat it from the study above and just blast more in to full charge. they skip any concern for heat which is a big omission. Id like to see you do that test too.
if you have a place safe for a possible fire and smoke and are willing to pay for the charger and have a temp sensor and a way to monitor each cell (even 10 dollar stick onto balance ports) that’s all that’s needed. 30Q is 3ah and at 5c with a 12s4p pack…15 amps each cell and four in parallel…60amps. PLEASE TAKE VIDEO!! Or maybe just try one cell first at 15. my supply will do 10 and maybe i’ll just try that. someone is supposed to step in and say you shouldnt do this.
only 50 amps but still. wire in a wattmeter.
