Shafiqul Islam's review emoji-happy
Review by Shafiqul Islam
এই বোর্ডটি অনেক ভালো কোয়ালিটির। ওভারচার্জ প্রোটেকশন ঠিক মতো কাজ করে। ব্যালেন্সিং ফাংশন ব্যাটারির ভোল্টেজ সমান রাখে। হিট সিঙ্ক দেওয়ায় লোডের সময় গরম হয় না। টাকা দিয়ে কেনার মতো জিনিস।

এই BMS বোর্ডটি সত্যিই অসাধারণ। হিট সিঙ্কসহ আসায় তাপমাত্রা নিয়ন্ত্রণ ভালো হয়। ব্যালেন্সিং ফাংশন ব্যাটারির লাইফ বাড়ায়। ১০০এ কারেন্ট সাপোর্ট করে, আমার সোলার সিস্টেমের জন্য পারফেক্ট।

I used this BMS for my DIY 12V LiFePO4 battery pack. The build quality is excellent, and the balancing works perfectly. Overcharge protection is accurate. Highly recommended for e-bike or solar projects.

Good product overall. The heat sink is sturdy and keeps things cool. I tested the over-discharge protection and it cut off at the right voltage. Value for money. Works well with my UPS.

আমার ই-বাইকের জন্য এই বিএমএস কিনেছি। ৩০০এ পিক কারেন্ট বেশ কাজে দেয়। শর্ট সার্কিট প্রোটেকশন দারুণ কাজ করে। ব্যালেন্সিং ফিচার ব্যাটারির আয়ু বাড়ায়। সবার জন্য রেকমেন্ড করব।
