Hawkeye Innovations 50Ah/58Ah NMC Battery
From years of testing lithium batteries, we have never tested anything quite like this cell. It is the best battery we have ever tested - period. Wave days of voltage sag behind with this beast of a battery. This has been the go-to battery for the past year, and a must have for high performance builds where power and/or energy density is important. This battery far exceeds any Tesla module. Please note that this battery is recommend for more advanced users.
We work directly with the factory to get these cells, and you will receive a QC report with cell serial number and corresponding voltage, capacity, and internal resistance for every cell in your batch. There are many fake clones out there, but our cells are brand new from the factory. It is recommended you contact us for lead time and current pricing. Typical voltage balance is usually within 0.003V - because they're from the factory.
We also have the 58Ah version as well, which has an energy density of 231 wh/kg! It is the same footprint, but only a few mm taller. (This is what we use in our battery packs). Please see spec sheets below with our in-house testing.
