High drain, continuous use, and fast charging can easily kill the battery in 6 months. Lots of people testing brushless have also killed the electronics package… motor controller, bms, sensors, cpu, etc. just more shit to break.
Also, you had to ditch your cordless with unfixable brushed motors didn’t you?
Befor that you ditched NiCd for Lion
You ditched again for 12v
Then again for 18v
Now we have 40v… ditch, ditch, ditch.
So brushless comes out… you ditch your old cordless brushed.

Brush motors are a PITA to service on a regular basis. If you are using them on every day duty cycles they will burn out every two to three months and need replacement. So while they might last forever, the service and maintenance costs are higher due to labor.

Kobalt has reasonably priced batteries. Generic, higher quality dewalt compatible batteries are $65/pair. Use an OEM DeWalt charger though. Those will work with the brushed, 18v dewalts with a simple adapter. DeWalt makes one, and there are numerous 3rd Party ones with a USB charger port.

Brushed power tools are among the most popular of construction power tools on the market for people who actually run businesses, not people who have a collection of tools they never use that collect dust in a garage. Brushed tools are cheap and easy to maintain while parts are plentiful and afforable.

Those are brushed. They make contact with the commutator which spins along with the motor coils. It is the way the electricity gets to the spinning armature, and also what makes the electricity switch between the three coils to make the motor turn. Keep the brushes in case the one on the new pump ever wear out, though that will realistically be in a few years

I have the same setup. Use the IEIK (eye eee eye kay) pump from Amazon. I had the bayite pump, and the way they attached the motor to the pump is flimsy, causing the bearing to fail. Same thing; ran for 5 months then failed, swapped w the IEIK and haven't had issues.

Your panel should not be direct feeding the 12v pump. Overvoltage will cause premature wear. There is a potted 15-40v to 13.8v converter. The pump is down in the woods, so the panel is connected into 12/2 landscape wire; 300 ft downhill is the pump. About 100ft in vertical drop. The converter box is right before the pump.

Because the spring produces less in the summer than in the winter, add a 1203BB speed controller, or the larger 40/60amp stepless motor controller, available for about $15. No model #, look for stepless motor speed control. Consider using a motor that pumps more water, and using the stepless controller to reduce it's duty cycle (speed).

I bought decent tools so I didn't have to "ditch" shit. I still have a good M28 Milwaukee battery from 2011 and the only one of the V28 (much older) tools I had to repair was the angle grinder I overloaded by modding the guard for 6" cutting disks. I'm not kind to any of my gear. Later buys, all still serviceable, include DeWalt and Makita brushed and brushless. I've rebuilt tools perhaps longer than you've drawn breath so maintenance is NBD.

12V was obviously a ick joke. Did not buy.

I still have and use my corded and pneumatic tools where they serve best. Not being poorfilth I don't need to exclude useful options, and cordless is glorious for mobile work where no air is available and I don't care to drag my CO2 cylinder because cordless also outperforms that, too, except for tire inflation. Thanks to inverters my corded gear can go anywhere too. Shit's easy and cheap if you think to do it.

>>2664533
Makita may never have made a bad grinder. Their ancient aluminum grinders with Bakelite handles still turn up and they're every bit as good as a Black and Decker Wildcat (from when B&D kicked ass).

I'll say this much about it though, if you get a nest of spiders in a 20V brushed tool's motor the web silk can wind up around the commutator bars isolating them from the brushes then ya gotta either hand-spin the thing forever to get it to work again or take it apart and clean it. I hate spiders. But ya gotta hand it to that silk shit, it's amazing.

Anyone with half a brain can deduce from context alone if more than one posts follow the same ideas, and if you're the same person posting about different stuff in the same thread, so what? that's kind of the point of anonymity.
