48V 50Ah LiFePO4 Lithium Battery - Bluetooth, Heating, Waterproof

Why so heavy?

I like the battery, both blue tooth cell monitoring and internal warming for charging in freezing temps seem like good investments in durability to me. Though I would have considered a smaller 48V X 50AH battery, the IP67 rating was important to me, and the larger size gives it a density that should make it buoyant in salt water. IP67 wouldn't mean much as you were watching your battery sink below 1 meter. Still I wonder why it is advertised as 10 lbs heavier than other 48V X 50AH LFP batteries. Mine actually weighs 70lbs which is even 4 lbs heavier that the posted 66lb weight. Not a deal breaker just 4-15lbs more to carry, which will feel heavier in the 10 years I expect this battery to last.

Great batteries

Quality Battery

Hands-down much better than the lead/acid batteries it replaced. I like the app a lot to be able to monitor the charge and state of the battery. And shedding 300+ pounds of weight was a huge plus.
