Lead-Acid Battery Powered Table Lamp Modified To Use Lithium-ion Battery
This rechargeable table lamp my family use to light up kitchen whenever there’s power failure. It uses lead acid battery for power, which I usually change whenever battery is bad, however because it’s fake of same battery that full market now and it’s charging circuit does not have anti-over voltage charge, I decided to modify it. I had modified it in the past when the original board got burnt, to charge directly with the use of phone charger, having removed the original board, picture below:
Now I’m using 5v lithium-ion battery module which I purchased from Aliexpress to modify it.
