/diy/ - Do It Yourself

That’s because that Bosch battery is 21700 cells. Ridgid did a 5S pack with 21700 cells on the 3.0Ah Octane pack. Might want to look inside too, like DeWalt packs are always quite small because there’s no BMS board in there, the tool does it,

It’s a store brand, so they’re not going to put out as many battery choices as DeWalt who has 3.0’s and 4.0s in both 5-cell and 10-cell. Glad Ridgid finally did the 8.0 though, I sort of want one of those for reasons, and they have a 12.0 as well, those are their only current 21700 cell packs. I will say though, the 4.0Ah packs like that Bosch probably aren’t great for power hungry tools that want bursts of lots of amps. That Ridgid max output is going to give a tool more max torque without overheating. There’s a balance between capacity and charging/discharge rate and life cycles, so I guess Ridgid thinks the 10-cell 4.0s have a better balance for their tools than a 5x 21700 cell 4.0Ah pack.

Also fun fact, if you watch all the testing channels, the Milwaukee and DeWalt tools do best with their 6.0Ah packs that are 10x 3000mAh 21700 cells. They consistently do better than the 8.0Ah packs with the 4000mAh 21700 cells because lower capacity generally means more discharge current. But those M18 and DeWalt 6.0s are big compared to the 6.0Ah packs made with 18650s.

Also you could do a 3.0Ah pack the same size as all of the 1.3Ah-2.0Ah packs, but they would only be good in lower draw tools, impact drivers and subcompact drills and lights and radios.
