⚡ 3S 4S 5S Li-Ion LiFePO4 BMS (Convertible 3S to 5S)
এই BMS টি মূলত 3S 4S 5S Li-Ion LiFePO4 ব্যাটারি প্যাক এর জন্য ডিজাইন করা। তবে বোর্ডে একটি ছোট কনফিগারেশন অপশন থাকার কারণে এটি প্রয়োজন অনুযায়ী 5S হিসেবেও ব্যবহার করা সম্ভব।
🔧 কিভাবে কাজ করে?
বোর্ডের B1 লাইনে একটি ছোট রেজিস্টর (0Ω jumper) থাকে।
- ডিফল্ট অবস্থায় (রেজিস্টর লাগানো থাকলে) → এটি 3S/4S/5S BMS হিসেবে কাজ করে
- যদি সেই রেজিস্টরটি সরানো হয় → তখন এটি 5S BMS হিসেবে কাজ করতে পারে
📌 কাস্টমারের জন্য গুরুত্বপূর্ণ তথ্য
- এটি একটি ডুয়াল-ইউজ (3S / 4S / 5S) BMS বোর্ড
- সাধারণ ব্যবহারকারীদের জন্য 4S সেটআপই ডিফল্ট এবং নিরাপদ
- 5S হিসেবে ব্যবহার করতে হলে ইলেকট্রনিক্স সম্পর্কে বেসিক ধারণা থাকা প্রয়োজন
- ভুল কনফিগারেশন করলে ব্যাটারি বা ডিভাইস ক্ষতিগ্রস্ত হতে পারে
⚠️ সতর্কতা
- পরিবর্তন করার আগে অবশ্যই নিশ্চিত হোন আপনার ব্যাটারি কনফিগারেশন (3S বা 4S বা 5S) সঠিক
- নতুন ব্যবহারকারীদের জন্য নিজে পরিবর্তন না করে টেকনিশিয়ানের সাহায্য নেওয়া উত্তম
👉 সংক্ষেপে:
একটি বোর্ড – তিন ধরনের ব্যবহার (3S / 4S / 5S), তবে সঠিক কনফিগারেশন খুবই গুরুত্বপূর্ণ।
