Brake light and a powerful battery.
Nice bright brake light. Good charge. Shipped on time. Pretty heavy, but I love that the rack was made for this battery pack or vice versa. Good product.

serious registration issues
Installation was easy and I like the rack setup. I had to extend the motor connection and the extra plug that came with it was very useful. My only complaint is that when I used their site to register for warranty they tried to set me up with an account for music, and charged my card $39 without telling me. Luckily, Visa cancelled my card because of fraudulent activity. Sorry, Vastram, but for that you"re lucky I didn't give you 1 star

Heavy but well-built. Definitely handles the stated output.
I paired this battery with a CYC Photon motor, and it works great! The only adaptation I had to make was to change the XT60 connector on the battery to an XT90 to match the motor's plug with one of these: https://www.amazon.com/gp/product/B06ZY34369. To date the battery has held up well. On an 18 mile ride on pavement with wind and small hills, the pedal assist didn't even use 20 percent of the capacity. It actually registers 52 volts, but if your motor has adjustable settings, be sure to call it a 48 volt battery or it will appear to empty much faster than it actually is. Be aware that having this much weight just under or at saddle height will change the handling of the bike, and make sure you are able to adjust your kickstand for stability when parked. After having a different brand of battery fail after moving through a considerable rainstorm on our vehicle's bike rack, I remove the battery before carrying the bike for long distances on the rack. The weight reduction also helps with lifting the bike onto the rack. I'm definitely pleased with this purchase!
