I’ve been planning a conversion on my 2000 chevy s10 with the emrax 348 for a while, and I came across these while searching for a battery. They claim a charge / discharge of 50C and 60C respectively. Wtf. The brand is reputable though, but I didn’t think this was possible …
Lithium iron phosphate batteries like these do have very good charge and discharge rates, but they are usually much heavier per energy kwh than lithium ion. Lithium iron phosphate has better kw/kg but worse kwh/kg than lithium ion. What is best depends on your use case.
