Gtk 16S 48V 40AH 50Ah Lifepo4 lithium battery pack with 50A 80A Bluetooth BMS APP for 2000W scooter bike tricycle boat go cart

Bluetooth BMS lets me monitor from my phone. 40Ah runs my 2000W motor for hours. LiFePO4 holds voltage steady. Size can be customized – mine fit perfectly.

I received the 48v 40ah battery that I ordered and it works fine. This is my second time ordering from them. It was nice of them to answer all of my questions promptly and I will probably place another order in the future. Thank you

Thank you

Friendly seller plus a high‑quality, long‑lasting battery product.

I'm extremely happy with my purchase. The battery looks very professionally built, and all of my special requests were fulfilled perfectly. I asked for extra on/off cables, and they even added a switch. I also asked them to expose the UART port, and they added a proper connector instead of just loose wires. The battery arrived with all cells perfectly balanced within just 2 mV — excellent! Customer support was outstanding. They kept me updated throughout manufacturing, provided exact sizing information, and were always very friendly and helpful. Shipping took some time, partly due to the situation in the Middle East, but they communicated all tracking changes. Excellent quality and service — I would 100% recommend this shop!

Excellent product, holds power for months without discharging. Perfect for backup devices and emergency kits.
