I received the batteries from the owner of Formuladrc.com. He got them as a samples to test out and I got the opportunity to do some damage to them. Bigsquid tested the 5000mah hardcase out. But they did not do 100A burnouts for 20 seconds(overgeared speedrunners scenario). Bigsquid also didn't provide graphs. I'll post the results of the 5000mah 40C pack out, as soon as I find some time to test.
I found about Acepow on rcgroups and rcu last year. Then saw them on biqsquid and boom like majic they were in my hands.
