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!

Nice video, malinaw!! Subbed

[@russellmontielmontojo1974]

idol pwede.bang.bumili nlng ng ready made.lifepo4 battery na may bms at.ilalagay nlng sa solar fan?

[@haidatlaai7185]

how long to Solar 7.2v charge the battery ?

[@LarryEspejo]

sir anong pang charge gagamitin pag low batt na

[@deovannetabada1018]

Boss paano yung charging ng battery? Ok lng yung original saksakan ng fan gamitin pag charge ng battery? Wla po bang problema kng charger ng lead acid battery yung gamitin pang charge sa lithium ion?

[@dnepisowifi3394]

Sir meron ako nabili 3.2v kada isa pero nak series na ung 4 pwde ko ba ilagay sa ganyan efan same model tayo eh

[@richiesalvador9457]

dpende kng ano ang orignal battery ng fan mo. kng 6v or 12v. 6v-2 cells, 12v-4 cells (in series). Need parin BMS for protection ng cell at unit mo

[@MoonArk]

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

[@nmode7821]

pano malalaman pag full charge na ang lifepo4?

[@reygrejaldo2324]

good day po bosss tnong lang po. pwde ba ung battery na nsa pangbluetooth spkr kailangan ba lagyan ng bms board o hindi pagnagseries ka.salamat boss sna mapansin nyo po.

[@richiesalvador9457]

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

[@gee620]

May pagkakaiba po ba kung ang gagamitin na battery eh male at female yung end ng battery?? or need ng male to male??ty

[@zachcura5782]

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]

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

[@masterbors6036]

Meron ba bms

[@keviyahana]

Pwede po ba ung 18650 ang ipalit gagana kaya pag icharge using built in cable? Or better mag lifepo nalang ?

[@richiesalvador9457]

lifepo4 since swak sa 6v. pag 18650 pwede pero di mo magamit full capacity since limited sa 6v

[@keviyahana]

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]

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

[@learntomakemoney1425]

Sir ano ginamit nyo pang charge yung sa dati ba na pang charge ng lead acid?

[@richiesalvador9457]

same with lead acid. pinalitan lng ang battery.

[@sealedwithabliss3254]

How do you charge it?

[@richiesalvador9457]

The efan already comes woth an ac cable. It charges the bat

[@sealedwithabliss3254]

@@richiesalvador9457 oh thanks. I thought charging of lead acid is not the same as LiFePO4. can you do also a little experiment converting solar floodlight into recessed light?

[@charlesgayon8738]

Sir tanong ko lang po. Na sira po kasi yung panel ng solar fan ko gusto ko po sana palitan ng panel na 12v 18watts pwede po kaya yan di po ba masusunog pag yan ang pinalit ko?

[@taejinjin9722]

Kung anong voltage ng panel na nasira same Voltage din dapat ipapalit

[@elizermacaron5983]

Hi Sir, kapag ung built in nga charger sa Fan, Kaya po ba niyan full charge yung lifepo4 na ininstall niyo?

[@richiesalvador9457]

yep. around 4-5 hours ang run time

[@zaldyjose4780]

Sir mag cut off po ba yan pag full charges na hnd na ma over charges ung bms

[@richellemercado59]

pang 2s po ba bms nyo po? specs pp ng bms nyo po sir?

[@richiesalvador9457]

2S 10A 6.4V LiFePO4

[@juantinker1525]

ano po specs ng bms

[@richiesalvador9457]

2S 10A 6.4V LiFePO4

[@philipsalvador8269]

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..

[@weresheep9045]

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?

[@ednacordova7842]

Di na kailangan Ng BMS?

[@richiesalvador9457]

need pa. 2S 10A 6.4V LiFePO4 BMS

[@megaraitei]

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]

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

[@kuyamonvlog]

Batt lang ba pinalitan?ano pang charge at ilan oras tinatagal?

[@richiesalvador9457]

Yes bat lng. Same charger na kasama ng fan. Mga 2-3hrs from 1hr before
