Did I get scammed by Temu?!! 300Ah Lithium Battery (DumFume) Review.

Turns out, this battery is AWESOME!! With my coupon from Temu, I only paid around $171 for one 300ah LiFePO4 battery!! Most of the so called name brands on Amazon or Ebay sell their 100ah batteries at this price.... It is pretty mind blowing deal.
I was trying to upgrade the battery system for my little DIY trailer camper (will do a full review of this trailer camper in next video), and ran into these supper cheap DumFume 12.8v 300Ah LiFePO4 batteries on Temu.
I love Temu, so, I decided to give it a shot and have this thing reviewed.
