The NAATBatt Lithium-Ion (Li-ion) Battery Supply Chain Database is a directory of companies with facilities in North America representing the Li-ion battery supply chain.
In short, the consistency of each cell's voltage, internal resistance, capacity and self-discharge rate (K-value) is crucial for a pack's safety, efficiency and lifespan. When cells are matched (like synchronized rowers), they share current evenly and age together.
To create a 72V system, you typically need around 20 batteries connected in series, assuming each lithium-ion battery has a nominal voltage of about 3.
Scroll any battery listing and you'll see the numbers: "Made with 21700 cells!" touted as the clear upgrade over the older 18650 standard. The implication is simple: bigger number, better battery.
This state-of-the-art rechargeable 60V lithium battery pack is expertly constructed with high quality 18650 NMC cells, delivering a lightweight, reliable and long-lasting power source.
