I need help to extend the runtime of the ups board (see attached image).
This is ups board for a CM4 which has 3 18650 cells in parallel. Can I extend the 3 cells to 6 cells for a longer runtime? by soldering a wire to each of the battery terminal and connecting it to a separate battery case with 6 cells.
Thanks and kind regards,

Hi everyone,
I'm working on a JVC TV for a client that's stuck on the "Wisdom Share" logo screen.
It's a model LT-50N795 with a board number TP.HV510.PC822. I attempted a firmware update via USB, and while the upgrade was completed successfully, the TV is still stuck on the Wisdom Share screen on reboot.
Has anyone encountered this issue before, or does anyone have any suggestions on possible solutions?
Thanks in advance!

Hi friends
I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board... -
I bought a case of them the battery cells are made in China the charge curve looks decent for 1 amp charging rate there is also a BMS protection board which here is the website link to them

I have a Pioneer PDP-427XD TV, not many hours on it. Bought second hand, I think it must have been a TV used in a meeting room, as it was like new when we got it. No manual, but worked out most of it.
The Problem I have now is it went out with a crack noise, then a blinking LED, if I remember it had 6 flashes.
I had a look and after a bit of hunting around (very frustrating as TV shuts down after a few seconds), I found a Capacitor on the Scan Assy Top Board had cracked and tried its best to meld down. Now, as it happens, I can get to this capacitor, but not the others...
