The charging profile of the fan fits. The problem is the bms that will cut off at 12v is the issue here. Unless you act as the living bms i.e monitoring spirit grin. I am a living bms though.

My reason is to know d actual ah.it will help.your calculation.

I have some like that,that d capacity was not written on it,then Google Inscription on it.

Battery diy is not that easy o.Respect to those that we met in front o,among them that is always ready to share knowledge,time are dollar naira, penuelseun etc

You need money,tools,time,knowledge,ion because some times you will get tired.

I have being buying tools dat could be of help,yet I haven't start big project but I know I will get there.

You can easily build an LVD for that fan using a 555 timer IC. There is a circuit online where it is built like a controller, which I think you can adjust the turn on and turn off values to make it work as an LVD.

Hello gurus.
I need a built package that can
1. Charge my PC (HP 15 11th gen, s type C)
2. power rechargeable fan (or DC fan)
3. power router
4. power one light bulb

...for 6-12hrs

Dollarnaira, Penuelseun and other bosses, I missed out on something like this you built months ago (dollarnaira I think). Abeg help me build as I don't think I can handle this DIY myself, make I no burn Lagos.

I can alternate between the PC and Fan. I can also leave out the bulb.

Noted.
A 12v or 5v dc bulb will suffice.

I discarded the UPS and went for a sachet inverter, on a full charge, I use it for 3 nights for fan and sound system.
