Ponilion's LiFePo4,5-33C LiPolymer battery

It's better to buy cells from big companies. Based on my knowledge, there are three big players at China: BYD, BAK, and TS. hehe, that's great advice. BYD,they would like to cooperate with Car factories or other bigger companies too,and they use LiFePo4 batteries for themself,from my personal ,i th...

Hi Jackhyq, my EV will be around 640 Volts nominal (224 cells in series) and range isn't that big a deal for me, so the ideal cell for me would be: 10-20Ah cell >=30A continuous discharge >=150A peak/pulse discharge for 10 seconds >=5C continuous charge >=100A pulse charge (10 seconds) low internal...

Cycle Life

I see batteries as a running cost, not a conversion cost. It is the major running cost. More than everything else combined. Thundersky have recently started advertising 3000 cycles at 70% DoD. I recently read on Lifebatt's US site that they'll do 3000 full cycles, but 10,000 cycles if you go < 72% ...

Ox / Bull Both hooved four legged ruminous bovines typically with horns. But on the iconic front - Ox represents povity, sufference, hard slog. Bull represents bravery aggressive forward movement, energy ! I had to laugh at the subtle loss of meaning in translation. http://forums.aeva.asn.au/smiley...

Home grown BMS ideas !

Are there any specs on the chargers - like current required for float switch? I'll assume not so how hard would it be to gently test a couple of them to determine what the current at switch point is? I suspect this might have to involve a longish time (a few seconds at each current) unless they don...
