What 18650 for portable vacuum

[quote=jp9mm]

I rebuilt easily this battery, but doing a power MOD.
I took 10 of lgdbmh11865, and I built a 5s2p battery. Now it lasts forever! And 2p solution gives enough current it needs with almost no changing of temperature.
You have to:

  1. Disassemble the whole battery, and cleaning inside the shell removing every plastic part and support;
  2. Desolder BMS circuit from battery and reuse it in the new configuration;
  3. build a new battery back, five side by side, negative and positive poles alternated, so that each one is in parallel with the same in the other row. Every couple is in series with the next one.
  4. I slightly desoldered LED, to put it horizontal and in front of the transparent plastic lens;
  5. solder wires in the same sequence at the new battery;
  6. fix everything with hot glue (not a ton);
    7)Clean everything with happiness!

it;s a lot of trouble
what if the motor quits before the new batteries.?

i;d just wait

what is your actual problem that you hope to improve, and what is the goal?
