Spare battery costs

[Allroads]

I recently purchased the M2S Sport R500 Commuter. It has the integrated hidden 48v 14ah bat into the frame which now so common. A one size only with no room on the frame to add it.
I decided to purchase another same battery. I can carry it in my panier for extended rides.
I contacted the manufacturer Reention thru Alibaba using Panasonic cells with all certification labels and one year warranty.
Reasonable at $304 plus shipping.

Reention does not build battery packs. They are a case maker.
