If there are tool shops in your area, hit them up for old batteries. I'm having good success in my area. Like you say - 30Q and 25R are quite common.

You don't want to use laptop batteries at all in power tools. Because you want high drain current.

25R and 30Q are good options.

Personally, what I'd do if you want to upgrade/replace, look for existing power tool packs in store recycling bins. Pull the cells and bms out of the old packs, combine all good cells, and reassemble into a new pack.

it might be a good idea to not ask when going to Lowe's/HomeDepot (or similar places) and just go diving into the bin and take some electrical tape. When asked what you're doing, saying you are making the cells safer by taping off the connections otherwise it could cause boom because of shorts and pull out some of the packs that are not in bags already and tape them off.
There've been a few people here who have done this trick and were successful for awhile in collecting packs.

We don't. And that's our point.

Laptops don't need or use high drain cells because they don't need it.

Tool batteries are your best bet.

Yes, you are right. does not need high drain batteries. however, few manufacturers use high drain batteries. I need to find these manufacturers

1) ALL manufacturers who make power tools use high drain cells
2) ALL manufacturers who make laptop packs "don't" use high drain cells
3) If you are going to make a battery pack for powertools, you need high drain cells. Unless you are going to make a 4 parallel or larger pack to handle the amp loads. A drill for example can see upwards of 30A while drilling a hole in wood. A circular saw can see the same thing and have an initial startup surge of 15A or more (rotational mass)
4) We already told you where to get high drain cells. You MUST look for existing powertool packs. Check your local recyclers if you can get them from there. Post ads up on Craigslist, or what ever the equivalent is in your area.

Any battery from Milwaukee, Makita, Dewalt, Bosch, Hitachi and all the respectable others will have high current cells.

Yeah. So which laptop battery has a high drain current battery?
