DIY 2s 100mAh LiPo Battery!!! 

6years on, and this video still is a knowledge purpose for anyone watching . Thank you. anyway, what happens if we take the bms out? much appreciated.

Exactly what i was looking for. thanks! 👍

Thank you buddy! You saved a batteries life.

Thanks again, second time this video has helped me out.

Very cool. I cannot wait to see when you make a flea weight combat robot.

This is a nice tutorial, verry healpfoul

This was so nice to watch. It gladdens what's left of my heart to see these tiny, insanely powerful batteries in use by ordinary, regular guys at home ['ordinary, regular'? No offence intended, Ben!] and not boffins in secret research laboratories. My earliest fighting robots were built in 1987 - horribly crude things with monstous lead-acid batteries for drive, feeble 12v motors, and dodgy nicads for the radio gear. Truly awful - as were the bodged-together mechanical (!) speed-controllers. Yuk. Our unofficial 'Century fight-club' decided on a 100 lb weight limit and a £100 budget. We had to go large because there was no chance of making any small or beetle-weight or ant-weight robots - there was no way to power or drive them, so everything had to be huge and as heavy as a concrete badger's bum. Lithium-polymer technology has opened up a whole new world for modern builders, and that's incredibly important because it's made it totally normal for young people to get interested in robot design, fabrication, and electronics. And if I'd had access to the internet when I started out (didn't exist) and top-quality RU-vid channels like this (didn't exist either; Ben probably hadn't even been born), I'd have made far fewer mistakes while putting my first bots together. Might not have had quite so much fun finding out how things worked, though... ;-)

I know this is an older video, but I hope you still check to comments. What do you do about low voltage protection for this? Does the protection circuit on the two new batteries handle it?

Awesome video mate, ignore the know it all's, geez I was impressed with your solder setup! What was starting MAH on each of the small 1s batteries? And then what is end MAH for the combined 2s battery? Sorry if it was in the video or if it is obvious. Thanks

i followed this and made a 2s the balance lead is not correct my lipo charger wont read it or charge it i used the middle wire with the neg and pos from lipo like you did

also , what might be a good/useful idea is to just solder up a harness , so you plug them 2 lil lipo's in the harness , and it functions as a 2S lipo . this way , 1 lipo can be on a different spot then the other one . let's say your build is very tight , and this could be a nice solution

Could you put a link to where you found these batteries

How to buy 100 mha battery 🤔🤔

do i use the middle wire mine has a red at one end and 2 black

Use kapton tape to save weight 😬
