I forgot to mention sa video na hindi lang dapat babaan ang HVD kundi taasan din natin yun LVD. Never go below 90%DOD while discharging para po mas tumagal ang batteries natin. In short wag punuin ng sobra while charging at wag idrain ng sobra ang battery🔋 nyo.

nice video sir. very informative. kita ko agad pagkakaiba sa BC 12V100AH..dating 14.4v HVD..ginawa ko lang 13.9v HVD..dating 13.01v around 1:40AM..ngayon 13.06V na..maraming salamat po ulit.

Grabe sir, pag test lang ng resistance yong nirequest ko para sa mga hindi makabili ng mamahaling tester, pero may malaking extra knowledge, mas naintindihan ko na ngayon pagkaka iba iba ng battery at proper usage o pag gagamitan ng battery dahil sa charge at discharge rate, kaya pala li-ion (18650) kadalasan ginagamit sa mga battery operated tools. salamat sa pag share..

New subscriber sir...big help video mo madami ka ntutulungan sa mga kagaya ko wlang alam bout battery... ask ko lang paano computataion ng life cycle kung ang battery ay hdi akma sa dpat na capacity nya kung 6ah ay 5.5ah lang pala? Ilang cycle ang nawawala? Tanx..God bless

[@SolarMinerPH]

without the datasheet we can only guess. Lets say 3000 cycles sya. After 3000cycles 80% nalang ang capacity nyan. So 6000 x 0.2 = 1200 ang mababawas na capacity 1200 / 3000 = 0.4 ang nababawas every cycle may bawas na 500mAh so 500 / 0.4 = 1250 cycles used which means may 3000 - 1250 = 1750 cycles pang natitira. Hindi po yan accurate since hindi naman linear ang pagbaba ng capacity. Baka mas mataas pa nang konti dyan dahil sa unang cycles ay mas mabilis ang pagbaba ng capacity.

[@FaisalinDimasar]

Yang ganyan resistance detector mo sir, pwede rin ba yan ipangtest sa iba pang type ng mga batteries? like gel type and acid battery? Salamat po ng marami.

[@SolarMinerPH]

pang estimate lang po yan pag malalaking battery na hindi na mamemeasure ng tama

[@cordsmist776]

Boss ayun sa sinabi mo mas mababa ang resistance ng prismatic tama ba? Meaning mas maganda mag diy sa prismatic bukod sa mas madali na i-assemble?

[@SolarMinerPH]

ang sabi ko mas malaking cell mas mababa ang resistance. mas malaki ang prismatic so mas mababa resistance nya. if icocompare mo ang 100ah na 32650 vs 100ah prismatic halos magkalapit lang yan. pag nagparallel ka kasi bababa ang resistance nila.

Magandang araw Solar miner sir.. Good application ng theory to compensate lack of tools yung manual compute ng internal resistance. pwde po ba gamitin pzem015 to check internal resistance?

[@SolarMinerPH]

I think you can. I am just not sure how accurate it is. If you are going to use it on a single cell 3.2v or 4.2v you will need to provide an external power to the pzem

Pwede po. Sa mas malaking battery mas mahirap lang po kasi mas maliit ang internal resistance ng mga yan so mas mababa ang accuracy na makukuha mo.

Good day sir, pag 32650 lifepo4, ano ba ung pasok na IR pag fully charge ito para masabi mong brand new pa ung battery.. Salamat po sa maggng tugon..

5-6 miliohm May mga used cells din na nasa ganyan parin ang IR so hindi talaga sya clear indication na brand new ang cell its just one indication that the cell is probably still good

Salamat po sa video na to sir. May tanong lang po ako regarding sa pag charge ng battery, sinabi nyo po is dapat wag e full yung pag charge sa battery para humaba yung buhay. Pero sa iba naman na nababasa ko sinasabi nila dapat daw laging puno para po mas humaba yunh buhay. Naguguluhan ako sir. Hehe. Sana masagot nyo po. Salamat po. And more power.

[@SolarMinerPH]

Ayaw po ng mga lithium cells ang super puno at super discharged. Mali yan nabasa mo na dapat laging puno baka ang ibig sabihin nila ay hindi laging discharged dahil mas masama pa kung laging discharged. Mas ok pa na laging puno kaysa laging discharged.

[@kevingolena2746]

@@SolarMinerPH salamat po sa pag reply sir. Ok sir. Naliwanagan na po ako. Hehe. Kasmaa na dito yung lifepo4 sir ano? Baka mali lang tlga nabasa ko or mali yung pag turo nila. Sabi kasi dapat laging busog ang battery para laging healthy. Haha

[@SolarMinerPH]

@@kevingolena2746 I think it is not as prominent on lifepo4 versus li-ion and lipo cells where they degrade faster when left fully charged. Lipo cells even bloat when left fully charged. I will probably run a cycle test on my lifepo4 cells soon to prove if fully charhing cells will degrade your cells faster

for small battery lang ito. Pag malaki na battery maliit na ang resistance ng mga yun kaya you need a tester with better precision. Much better bili ka nalang IR tester talaga

Tanong lang sir, alin ang positive side at negative side,. Kasi sa pagkakaalam ko ang anode ang positive side at ang cathode ang nagative side, correct me if i'm wrong sis, Thanks.

Anode is negative Cathode is positive It can actually change depending on where the chemical reaction occurs but in our case lifepo4 the anode is negative.

Thank you Sir.. 👍

[@odedineros1122]

sir bakit kay DIY PINOY 40ohms gamit nya? wag daw bababa ng 4ohms ang gagamitin?

[@SolarMinerPH]

I dont know his reason kung bakit wag bababa sa 4ohms dahil we are using ohms law so even if you change your resistance you should still get the same result. Edit: After thingking about it, one reason would be it will be easier to get the voltage drop since it won't drop too fast like if you use lower resistance values the downside to that is you will have less voltage drop and accuracy of your result might go lower. I might test a higher resistance later and see how high the differences are.

any value of resistor can be used because you should still get the same value if you used a different resistor. I used 1 ohm because it just makes it easier to compute.

[@harasti]

You didnt explain that you showing two completely different method of measuring. First with resistor its DC method and with higher resistance for ebike battery it can show bigger difference compared to measuring with instrument which use AC method 1khz puls. Only measuring with instrument those type you can compere to technical data sheet. Measuring with simple DC method is for cheep way to find bad cell compere to other similar.
