james.1020 Posted January 1, 2020 Share Posted January 1, 2020 Hi all just a quick question as a vaper i have loads of 18650 and 20700 li-ion cells which are 3.7 volts 4.2 when charged so i was thinking if i was to get a sled off the internet for this size batteries then put a deans connector coming off it would this work fine in my brushed e firestorm?

CattoCattoExo Posted January 1, 2020 Share Posted January 1, 2020 https://www.instructables.com/id/RC-Battery-Pack-With-18650-Cells-3S1P/ in theory, yes it will work... in a practical sense, no, just use a lipo pack thats already tested and safe 1 Quote Link to comment Share on other sites More sharing options...
Bajadre Posted January 1, 2020 Share Posted January 1, 2020 Agree with catto depending on capacity of each cell but cant see it being worth it tbh if running 2s on a brushed setup better off with one of these https://www.ebay.co.uk/i/402011693056?chn=ps&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&itemid=402011693056&targetid=596596254901&device=c&mktype=pla&googleloc=1006567&poi=&campaignid=6619152134&mkgroupid=84510981728&rlsatarget=pla-596596254901&abcId=1140496&merchantid=6995734&gclid=CjwKCAiAo7HwBRBKEiwAvC_Q8RltZVBZTc-YBFnj8e5vUNj8xIWZbID9MSfsDyB2chFyOQTQAwLAZhoCvGMQAvD_BwE i run 2 of these in my 1/8th truggy @ 4s get around 15mins full pelt on tracks etc on a 1/10 lighter rc you should get 25min runs times for under £20 which is pretty fair or get the bigger sized ones 5200mah if u can mod the battery tray or just her in tight Quote Link to comment Share on other sites More sharing options...
james.1020 Posted January 1, 2020 Author Share Posted January 1, 2020 I have so many of these batteries and just thought it was a cheap way to use them as if in there own sled then it would be like using aa batteries just a lot better so when they run low i can just pop them out and put some new ones in the sled. the batteries are 3000mah and 4000 mah. Im not keen on lipo as its a basher for the kids and i feel like these batteries are safer. Quote Link to comment Share on other sites More sharing options...
Tug Posted January 1, 2020 Share Posted January 1, 2020 They don't usually have the discharge capacity for RC, could be more dangerous than lipo due to overload risk. 1 Quote Link to comment Share on other sites More sharing options...

What he said - discharging at a too higher rate could be every iffy.... Quote Link to comment Share on other sites More sharing options...

Im not keen on lipo as its a basher for the kids and i feel like these batteries are safer. Those vaping batteries (i'm pretty certain we're talking vaping batteries here, things like Sony VTC6, Samsung 40Ts etc?) have nowhere near the required discharge rate. A VTC5A is already stretching it, 3000mah and 4000mah batteries have a max discharge of around 15A safely. That's nowhere near enough. They're also lithium batteries, everything that goes for a LiPo goes for a 18650 as well. If punctured, ruptured or even shorted, you have a lithium fire at the very least.
