Is a question mark mandatory for a conversation? Is that what you are inferring?

I think not. If it was, we might expect a moderator to chime in.

Members don't need an invite to discuss matters raised. The OP raised their question. Others took turns to make statements.

The thread (like many others here) drifted, but that really isn't an issue in general, once the initial questions have been answered.

Take a deeper look at what certain individuals are posting and you'll see what I mean.

All this takes me back to when I used to run a modified car club forum. The lock thread button was my best friend 🤣

Reply - even 70A (debatable from the specs I've seen) isn't anywhere near enough for our 4S - 6S Rigs.

It's not really a racing Vs bashing matter. It's more a case of whether you think 60-70A is an acceptable limit for your surface model.

If it is - fill yer' boots! (And let us know how it goes).

70A / 1 cell would be 140A for a 2P or 210A for a 3P configuration. A 6S/3P battery built out of 21700 cells would be about 63x70x126mm or 168mm for an 8S pack.

Based on the capabilities of modern high-performance tabless cells, such as the EVE INR21700-40PL, a 2S (2-series) pack can achieve very high discharge rates due to reduced internal resistance.
  • Maximum Continuous Amps (2S Pack): Approximately 70A.
  • Peak Amps (Burst): Can exceed 100A for short durations.
  • Voltage: 7.4V Nominal (8.4V fully charged).
Key Takeaways for Tabless 2S Packs:
  • High Performance: The "tabless" structure allows these batteries to run cooler and maintain higher current output (35A to 60A+ per cell) compared to traditional tabbed cells.
  • Capacity: A typical pack using these cells, such as a 2S1P configuration, would have a capacity around 4000mAh to 5000mAh.
  • Usage: They are ideal for high-drain applications, such as RC cars, e-bikes, and drones, offering consistent power even at low states of charge.
