thanks for being here how lithium battery BMS works 3s BMS circuit diagram 3s 10A BMS review how to make lithium Ion BMS circuit product link: amzn.to/3FHox5c my instagram: / bhairabkr.mandal #lithiumbatterypack #18650 #bms #fclab
bhut he kamal ki video or bhut he achy say apny samjya hain humai maira masla yae ta k maine new battery banai to woh off hwa ta to apki ye video dekh kar main sab samjh gya or maira bms on ho gya thanku bhai Allah apko khush rakhy ameen.....🥰🥰🥰
अच्छी वीडियो, एक प्रोब्लम और एक इनफार्मेशन मेने आज ही एक 4s BMS लाया। मेने चार 18650 सेल को सीरीज में लगाकर इनको BMS PCB के नीचे जन्हा वोल्टेज लिखा है वहा लगाया।बटीरी और सर्किट गर्म हो गई।फिर मेने वीडियो देखकर सेल के टेपिंग ऊपर की साइड लगाया फिर कोई प्रोब्लम नही है लेकिन आपने भी नीचे ki side लगाया ,कोई गर्म नही हुआ? दूसरी बात ,ज्यादातर bms video मे ये बताते है की तीन सेल हो तो 12.6 volt charged मिलेगा ,इससे ज्यादा की कोई चीज नहीं चलेगी ।लेकिन ये चीज फुल वोल्टेज के लिए ही नही है ,इसमें 3.7, 7.4, 11.1 ऐसे वोल्टेज भी हो सकते हो।तो इसके लिए सेल टेपिंग ऊपर की साइड लगाओ।
एक और बात ,3s मे तीन सेल सीरीज में होता है जो सेल के वोल्टेज का sum करके voltage देता है लेकिन कॉपिसिटी इतनी ही रहती है। जेसे तीन सेल जिसका volt 3v हो और कैपेसिटी 500 mah की होगी और 3s में सीरीज में कनेक्ट करोगे तो 3X3=9 volt मिलेगा लेकिन कैपिसिटी 500 mah ही मिलेगी।लेकिन दो दो सेल parallal कनेक्ट करोगे तो वोल्टेज 3 वोल्ट ही रहेगा लेकिन कैपिसिटी 1000 (500+500)mah की होगी , ऐसे दो दो सेल पैरालेल करके इनको 3 s मे लगाओगे तो volt 3X3 9 volt ही रहेगा लेकिन कैपेसिटी 1000 mah हो जायेगी।टोटल six cell लगेगा। दो दो paralal फिर इन दो को सीरीज मे।
Bhai ish BMS KO 12.6 VOLTAGE SE CHARGE TO KARENGE PAR KITNA AMP ...?? PLEASE 🥺 ELABORATE (EXPLAIN ) OR 3S 40 AMP BMS ME KITNA LITHIUM BATTERIES CONNECT KAR SAKTE HAIN,???
Maximum 10 Amp. Depends upon your battery. You can connect any amount of cells in 3s xp configuration, x can be any. Just overload or short protection will trigger if current higher than 40amp flows. So less cells like 3s1p or 3s2p is not recommended, minimum 4p or 5p is required.
Bhai maine Amazon se ek 3s 20A BMS liya tha lekin wo 12.8 volt tak chala jata tha maine usse bike ki battry banayi thi jab maine output ke dono wire ko short circuit Kiya to MOSFET jal gya usne protection q nahi kiya
Bro ek chota sa sawal, yeh bms output ki situation me me kitne amps ka zatka le sakta hai, kyuki is battery pack ko agar bike me use karte hai toh bike ki self motor 40-100 amps ka ek zordar zatka leti hai kuch microseconds ke liye toh kya oos condition me yeh kharab ho sakta hai ya nahi.
Bhai mere pass same bms hai usme sara protection work kar rha hai per overcharge protection work nhi kar rha hai 13.5v tak bhi cut nhi kar raha hai isa kyu😊😢
Want to use 2S and make it of 7.4v can u please explain and help would like to have a circuit diagram and want to connect it with a 3W 8.97v 3A solar panel
Thanks bhai great learning about Li ion BMS. 👍👍 Please ek baat bata do aap kya ye bms controlled current deta hai cells ko ya just over charge nd discharge pe MOSFETs ON OFF hi karta hai. Kya hum isme charging voltage 20 volt tak denge suppose directly from solar se to kya ye BMS voltage decrease karke cells ko dega ya poora 20volt cells ko dega..? Please iske liye bms me battery connect karke fir charging and discharging MOSFETs ka ON OFF voltage check karke batana bhai Ye please confirm kardo bhai kyun ki ek bada investment karna lifepo4 battery me jisme mujhe without any Charge controller ke directly lifepo4 ko charge karna hai, please reply me Eagerly waiting for your reply
Yeh voltage control nhi karta hai. Bas on/off karta hai. To agar solar panel kam amp ki hai to thik hai, wo khud hi voltage drop kr dega. But agar high amp ki panel hai to buck converter lagana padega.
@@FreeCircuitLab ok bhai thanks Mera pannel high Amp ka hai 20volt me hai total peak current 20Amp Mai lifepo4 battery liya hoon Rs10000 me 100Ah prismatic cell wala Usme BMS laga hua hai 40Amp ka Mera sare pannel common positive single thik 35sqmm wire se connect hai and isse mujhe bahut faida hai night me yahi common +ve wire load ke liye v use ho jata hai. So mujhe N channel MOSFETs se pannel voltage 20 to 14 volt fix karna hai but +ve common hona chahiye please ek circuit bana ke bas reply kardo plz. Common -ve se to ban jayega but uske liye shayad p channel MOSFETs use karna hoga, lekin mai soch soch ke thak gya ki inverter me v to common +ve hota hai and MOSFETs to -ve supply hi transformer ko deta hai to mera voltage decrease circuit N channel se kyun nahi ban sakta hai, please reply me dost.
Are bhai aap homemade farad super capacitor battrey pack ke upar video banao na, Agar bana sakte ho to.....? Jisse bike ke battrey ka kharch our maintainens 0 ho jaye.
Bhai mujhe ek anti theif alarm banaye Jo touch Hana per activate ho bike ka liya aur power soure 3.7li batter inbuilt sa chala if possible with remote.thanks
Hi Bro I have (7 or 10) Bms 3 so can you tell me how to connect (two batteries) to Bms 3 because I want 7.4 out put from that is it possible if it possible can you make any video on that.
Do I need to connect (weld, solder) batteries to the BMS board in sequence (from plus to minus or vice versa) how is it in the laptop battery so that the board does not go into protection?
bro I need a help I have 1 3s 20a 12.6v Bms and its giving 1 volt less than connected battery pack like 3 cells are giving 12 volt but bms is giving 11 volt plz help bro and tell me solution
Ye sab choro TDA2030 wala variable power supply ka ic protection circuit banake dikhkhao, jald se jald👍🏻 Main try kiya hai, tmhara theory Se hi,, to please protection wala circuit banakar dikhao.
E-Riksha ka SMPS charger ko repair karte time bahut baar mein 48to 60 volt ki supply use karta hoon, but ise charging on to ho jati hai but charging show nahi hoti becoz batteries to load show karti hain but power supply ka load nahi hota, kya koi shunt resistance lagani padegi charger ke parallel & kitni value ki
Sir mene 2 cell parallel lagaya ha backup increase karne keliye and mein ab 2cell × 3 (series) mein connect Kia ha too mujhe 12 v battery pack milgya or mene backup barane keliye 2 pc lithium battery ak sath parallel mein connect Kia So . Mujhe konsa BMS use karna chaiye or kitna voltage and ampere Dena chaiye
Meri battery ma maina jab ya bms Laga toh jab bhi lod lagata hai toh ya out put ko cut kar da ta hai ya 4 volt tak la ata hai Kya AP bta sakta hai ka ya kui ho Raha ha
सर मेने 12volt dhrill के लिए 3s 20am bms से 4.5ah की बैटरी बनाई है जिसमे कुछ problam aa rhi है plss help.. 1. Bms se output kam(10-11volt) bata rha he jabki sidhe battery se chek kre to jyda (12.15volt) he 2. Drill chalane pe bms ke components garm hote he or drill Ruk jati he... Fir charger connect kre to chal jati he... Fir loud dene pe Ruk jati he
