yes it cant get full charged. but based on my computation, the panel can charge the battery up to 81% from 0%, not bad especially if you use it for 8hrs only. But we will still upgrade the panel soon. thank you 3.7v x 5ah = 18.5wh battery capacity 3w(solar panel) x 5hrs(sunlight) = 15wh 15wh/18.5wh x 100 = 81% *if I'm not mistaken
Boss pag palitan ng 3 crownstar 18650 3200mah 3.7 pwede?.. jn ilagay battery .. kse running 6hours sa Solar Crownstar GD-27 eh.. 100 watts po saken chandelier sa una lng maliwanag madali malowbat
Good day boss, pwede yan sir , suggest ko bili ka nun mga true rated na capacity, para matagal malobat. add ka narin ng BMS para protected yun battery mo. thanks
I love the videos. I would like moe information on the calculations required to increase battery size/Ah using the voltage and panel size increase to gain a full charge without over heating or needing some sort of regulator. 10 to 12 hrs is ideal for me.
sir.. anong mga gamit pang assemble sa battery at anong battery gamit mo.. yung sa akin kasi kaparehas ng ilaw mo. kaso yung 300W ko hanggang 12MN or 1am lang.
18650 battery gamit ko Sir. sa shoppe ko nabinili. dagdagan mo lang ng battery para tumagal yun ilaw. saka kung wala ka pang spot weld sa mga battery. bili ka ng 18650 battery holder. thank you
@@STARfishdiy1700 mah na tatlo piraso ok naba? 1s 3 amp bms ok na 18650 use ko sana, paano kung 6000 mah tatlo 2000 mah use ko, ok lang ba bms na 3 amp?
sir 100 watts cieling solar lights ko n dagdagan ko ng isang battery ok lang ? kasi 4 hours lang mhina n ang lights pwede dagdagan ng isang battery at ang solar panel di n plitan ng mlaking panel?
hindi advisable yun soldering iron kasi madadamage nya yun battery. meron po nabibili na 18650 battery holder sa shoppe/lazada. yun po pwede gamitin . thank you
@@STARfishdiy i see, ok po sir. Ask ko lang din sir yung tatlong battery na po ba ang protected sa isang 1s na bms mong nilagay? Ang pagkakaintindi ko kasi isang 1s bms kada isang batt.
Even not just for 80w just the solar charging can not charge the 3 batteries with same pannels or maybe with the same charging componnents, it will overheat, it can not handles the 3 batteries, it is not designed to do so.. It is only for single battery, maybe you can replace batteries with Genuine or HQ Brand its you can do least to extend the hours of use but not add more batteries.. Do not do any modification unless you understand electronics or you are professional technician.. DIY is good but not all posted here in RU-vid is accurate... I hope someone here will notice the difference.. My 15+ years of experience will give you assurance and this is my field of especialization.. I've bet good in DIYs not just a regular repair technician do.. Thank you
good day Sir, so far i dont have any problem in adding more battery and issue in overheating. and in my observation the light got better and lasted longer .thanks
@@ghlenmarkverzosa5468 Hi Sir , step up module yata yung sinasabi mo , pwde naman sir kaya lang sa specs ng solar kagaya neto 6v(3watts) lang . need mo mag add ng solar panel para mafull charge yun battery .
Good day Sir, its not as low because Im using it in the kitchen as a night light .the lumen is good specially in full bright mode and also the price(5.5 USD) is cheap and worth it. Thank you
