Күн бұрынTDL- Rebuild your own Lithium Batteries Roomba Robovac
There seem to be plenty of dead robot vacuums around if you care to go looking - thats because the batteries die and are really expensive to replace, assuming you find one in the first place!
Use this trick to rebuild your own Lithium cells, take care, be safe!
For this I just grabbed some 18650 lithium batteries and used cheap solder braid as the busbar. Try not to short anything, it could be a nasty result!
Amazon stocks plenty of these cells:
USA: amzn.to/2K8ezQu
UK: amzn.to/2MygkIq

Wow. That's actually really clever using solder braid as bond wire. Thumbs up Andrew!

Soldering 18650 is absolutely crazy idea. 😮

Why didn't you connect your orignal cells together to create a 4s2p configuration? to have a larger capacity?

@@backofficeshow I was a bit puzzled at first due to the different format :-) But I think it's maybe a good way to get a video out quickly. I'm assuming here that it's easier, what do I know? lol! Every step was well indicated visually. It's all there so I think it's worth continuing with that style perhaps at least occasionally. :-)

Nice video, thank you. I did for my robot here and I'm facing problems. All readings in BMS are ok, but robot is running for like 2mins and turning off. I changed half of cells because my old BMS and 2 cells were gone. I bought a new BMS, but it don't have the third wire (I'm suspecting this is a thermostat). Do you know more about it? I don't know if the new cells that I bought are bad or I'm doing something wrong.

Off the top of my head, yeah I think the third wire was a temperature wire. The 2 minutes thing is a bit suspicious, you don't think it could be a a bit too much load of a motor and the CPU shutting it down.

With those nasty cells you will probably need to recharge it every 10 min

Hm question. If you have an older vacum using good old Nimh batterys with a charging station. Wil you be able to change to lithium(18650/21700) batterys with no problems? I see in your video you have a circuit board that im guessing in some way is designed for lithium batterys. But how would a pack of these batterys survive on an 14.4Volt standard nimh charger?

Unfortunately not, you would need to replace with exactly the same type of cell chemistry unless you replace the various charging circuits and power supplies

I didn't buy them for the capacity, I bought them to see if the gadget worked, they were so cheap I was under no illusion that they would be their stated capacity :) Unless they have beat Elon Musk to discovering an amazing chemistry?
