- Here's the second installment of the drill battery powered rc car series. In this video I take the rc for a run, and so far it's working far better than I had ever hoped for.
If you like, comment, and watch most of the video, it makes TH-cam more likely to recommend my videos to other people, so it really does help out! - บันเทิง
@Fishin'Karts You're right!
The inherent danger of Li-Po where you look at them wrong and they flame or fizzle out is bad news. You only have to forget one step only once out of the multi-step charge/dischare/storage process every single time you use a Li-Po or it's dead or burning you and your house down around you.
Power tool batteries are built for construction site damage; big falls, crushes, even coffee. Li-Pos would explode even thinking about something like that. Power tool batts are designed for high-torque, burst and long-duration, high and low speed drainage. As to charging, my Makitas do 1Ah/10 mins, so under 1hr/6Ah = Sweeeet. Keep 2 or 3 batteries on hand with a dual charger in the wall and never run out of run time. While I haven't done any endurance trials as yet, I've only just finished the conversion and don't quite have the room/time at the moment for extended testing. Tests are coming though.
As to cost, my generic Maks are sub$5/1Ah and heading to $4/1Ah. Even if one generic is lower quality than another one, a brand label would cost the same as three generics. I've killed a few and the BMS has cut in every time so far without fail, shorting itself instead of sparking the lithium. I leave them fully charged for up to weeks on end and have never had one let me down.
I made the change for the versatility and ubiquity of it. Pull the battery from the drill into your RC car onto the charger into the skilsaw back to the RC car and so on. In my case, I also build robots, so can pull from one to another at events. I do have an 18v (5S equiv) caveat to deal with regarding the Arrma BLX185 ESC as it thinks 5S is really a dying 6S battery so cuts power to save the battery even though the battery is full charged. Be aware of that in your own conversion, dear reader! Others likely don't have this issue.
Conversion is well worth it if you are already invested in a given power tool setup and: Don't want to invest in yet more new batteries and chargers and fire-proof charging bags; Or you just don't like the idea of requiring fire-proof charging bags to charge a battery. Slap it on the charger and walk away. Let the on-board BMS do the balancing and nonsense maintenance itself.
Glad to see I'm not the only one who did this, nor the first!
Just use my 18v in my rig today before I looked up videos on it. I was racing cars down the side streets it was so fast. I'm sure the electronics didn't like it but it's going to happen a lot more now.
Haha sounds like fun!
I used a 12v makita. what a difference
@@larryb4447 I was hoping to use 18v Makita, but the Armma BLX185 has a dead-zone for 5S as it thinks it's a dying 6S battery and shuts down. The Mak 14v is same form factor/charger etc as the 18v, so am going with those for now. Though my Senton will take 6S and I wanted to run 5S, I am defaulting to 4S equivalent.
Did this today with my kids r/c before researching it, found the motor is getting hot but goes like a shower of shit lol. I only did it for giggles and see how it would go, the original battery takes so long to charge and only last 15 minutes, I have a stack of these batteries ready to roll, maybe I’ll put a variable resistor on it and sacrifice some power for less heat in the motors, which would then give me longer run time cause I’m having to stop and let it cool 😎
Maybe do a quick connect for the body so the battery can go on top.
Nice! Is there a big difference in weight? The battery seems so much bigger that it might interfere with the speed?
The small ones don't weigh much more than my largest 2s lipo, but the big does weigh a fair bit more.
My drill batterys are rectangular and fit perfectly in my 4x4 monster truck it has insane torque it can pull a person and tops out at 12 mph
An 18v 6.0Ah Makita battery weighs 495g. The sample range of 5S 6000mAh Li-Pos ranged from 600g - 800g. Add 100g of battery adapter and the Makita is as light as the lightest Li-Po equiv I came across. Your results may vary.
How did you cut the drill handle off
It's actually from a tiller type tool that quit working. And I just used a hack saw I think.
@@fishinkarts2865 just have to cut at the right spot.
