Rechargeable Electric Fan Fixed! Lead-Acid to Lifepo4 Battery Replacement

In this video, I'll show you how I replaced the non-working batteries of a rechargeable electric fan. We know that lead-acid batteries have a short life span. Replacing them with lifepo4 batteries is so much better. Longer backup time, better power, and longer life span.
I managed to replace two of our rechargeable fans. It's easy to do if you have the right tools!

bos un fan namin ay 10000mah. 7.4v li-ion battery. ang charger nya ay 9v 2a sa wall. at 9v 1.66a naman sa solar panel. pwede ko ba palitan ng lifepo4 para mas tumagal ang andar. balak ko gawin na 20000mah or kahit mas mataas lang sa 10000mah. pano po ang connection? kapag lifepo4 gagamitin na battery at kapag li-ion. pano po connection na dapat ko gawin at pag samahin

your fan charge lead acid at to the max of 6.4volt. and your life04 battery cells to the max of 7.3volts which your fan charging circuit is not design for that voltage. in the end, your power supplied by the fan will not meet the requirement of life04 and definitely will keep under charge. red indicator light will always be on..

I have similar problem after replacing the SLA battery of my 12V fan with lifepo4, the fan's charger output is 14.4V which I thought is enough to charge lifepo4 to around 80-90% but when the battery voltage reaches 13.3V (3.325 per cell), the current drops to around 120mA and it now takes forever to charge. Is it normal to draw that little current at that voltage range or am I triggering some sort of overcharge protection designed for the original SLA battery?

Sir question po para sa FEL6112 model, kapag nakasaksak 12v dc input at naka disconnect AC circuit na my transformer may ilaw charge, pero kapag naka disconnect yung AC circuit walang charge na ilaw

@richiesalvador9457 10 ай бұрын

not familiar sa model pero alternative ang DC at AC. hindi pwede magkasabay. check mo manual ng unit.

Boss ung mini fan with lamp ko po kasi na firefly sira batt. Linagyan ko ng 18650 dalwa nagana naman. Tanong lang pano ko po siya i charge gamit nung built in ac nya? Or better na yang lifepo nalang gamitin ko n batt mas safe? Gnun din ginwa ko sa malaki na led lamp 2 18650 din. Pero lam ko d pedeng i charge e

@richiesalvador9457 10 ай бұрын

pag lead acid ang orig battery, mas better ang lifepo4. mas malapit ang voltage specs. pag 18650 di yan magamit ang full capacity. iba ang voltage specs ng lifepo4 sa lithium ion

Lithium ion 18650 yan. Pwede pero mas delikado. Mataas ang full charge voltage ng 18650.

P+ and P- are the battery output. Correct ? Are they also the charging input ? Coz I think that for li-ion tp4056 -- the charging input and the battery output are different terminals.

@richiesalvador9457 10 ай бұрын

depends on the BMS. some have separate charge and discharge. The BMS I used have the same terminals for both charge/discharge .
