52 Volt Downtube Batteries

[Joaquin Suavve]

I have decided to outfit my bike with a downtube battery: 52V 40A 20ah.

Are there better brands to research? Brands to stay away from? Any input would be greatly appreciated!

Many of us here have batteries from EM3EV and have had great service from them. This King Shark meets your specs and is on sale... although I am not sure what the tariff situation is and what the real cost with shipping may end up being.
