Hello all, I just read this thread with interest. I'm late to the discussion, but, its still valid.
Q is; does a battery exist that hits the points discussed - more Ah, equal CA, no BMS failure modes, acts like lead, but isnt lead or lithium , $600 , and is the same size as the RG 35A with 30Ah.....Yes Virginia, It does exist, and its NOT from earthx which everyone thinks is the holy grail of lithium batteries., . gee, I wonder who..? hmmm... thing is, it would not be certified, so, not sure about a discussion like this for a certified acft. ?
