I'm in the process of creating my own battery packs and I'm stuck between two options of 18650 batteries. Could anyone provide insight on how the 10A versus 30A discharge rates would affect performance in my configuration? Here's what I'm looking at:
1. Molicel M35A 18650, 3500mAh, 10A (5.50 CAD x 15, total $82.50)
2. Molicel P30B 18650, 3000mAh, 30A (6.50 CAD x 15, total $97.50)
Additionally, I considered a third option:
3. Molicel 21700 P50B, 5000mAh, 60A (9.25 CAD x 10, total $92.50).
Here are my planned configurations:
- M35A: 10.5Ah, 189Wh, max discharge 30A
- P30B: 9.0Ah, 162Wh, max discharge 90A
- P50B: 10.0Ah, 180Wh, max discharge 120A
I'm particularly curious about how the different continuous discharge rates will impact performance with high-drain tools. Any guidance would be greatly appreciated!

If you're considering these cells, keep in mind that the 10A M35A cells won't perform well under heavy loads. For tools like saws or grinders, you’ll probably want to go with the P30B or even the P50B for better performance. The P30B, with its 90A discharge rate, is a solid choice for high-drain applications. Plus, it’s one of the best 18650 options out there!
Thanks for the advice, that makes total sense!
