I bought this for a Li-ion scooter battery. Works flawlessly with 13S, the Bluetooth app is user-friendly, and the balancing accuracy is impressive. Delivery was fast and packaging was secure.

Review by Ayesha Khatun
এই BMS টা আমি আমার ইলেকট্রিক রিকশার ব্যাটারিতে ব্যবহার করছি। ব্লুটুথ কানেকশন খুবই সুবিধাজনক। ব্যালেন্সিং একদম নিখুঁত। তবে ১০০এ ক্রমাগত ডিসচার্জের জন্য ভালো কুলিং দরকার।

এই BMS টি আমার DIY সোলার ব্যাটারি ব্যাংকে ব্যবহার করছি। সেটআপ করা সহজ, অ্যাপের মাধ্যমে সব প্যারামিটার কন্ট্রোল করা যায়। অ্যাক্টিভ ব্যালেন্সার খুবই কার্যকরী। দাম একটু বেশি হলেও কোয়ালিটি ভালো।

Good BMS overall. The active balancing is effective but I expected a higher balancing current. Bluetooth works fine. For the price, it's a decent buy. Used for a backup power system.

I've used several BMS units before, but this JK is on another level. The active balancer keeps all cells perfectly matched, and Bluetooth range is decent. Perfect for my 14S LTO pack.

জে কে বিএমএস খুবই নির্ভরযোগ্য। ৮ থেকে ২০ সেল সাপোর্ট করে, তাই ভবিষ্যতেও ব্যবহার করা যাবে। কোলম্ব কাউন্টার ও টেম্পারেচার প্রোটেকশন আছে। ইভির জন্য আদর্শ।

Review by Tanveer Hossain
প্রোডাক্ট কোয়ালিটি ভালো কিন্তু দাম একটু বেশি মনে হয়েছে। ব্লুটুথ ফিচার সুবিধাজনক এবং অ্যাক্টিভ ব্যালেন্সিং কার্যকর। টেম্পারেচার প্রোটেকশন আছে, নিশ্চিন্তে ব্যবহার করা যায়। ডেলিভারি ভালো ছিল।
