So far, so good
I bought an e-bike from Luna Cycles in El Segundo, CA in early 2017. The bike came with an in-house assembled battery without any info on the brand of cells used.I’ve ridden the bike for several thousands of miles (pedal assist 99% of the time) without any problems from the battery. There has been some degradation in range in the past year or two, but not to the extent that caused me to worry about it. I only ever charged it to 80% maximum, and would recharge it when it was at 20%.When the original battery gave up the ghost, I naturally checked with Luna for a replacement. It seems they have moved way beyond selling batteries…This battery is an exact replacement for the original in voltage, amp hours, overall dimensions and mount.This was a simple plug and play solution.The seller states the cells contained in this battery are manufactured by LG.So far, I’m extremely happy with the performance. I’m getting more range (about an additional 3 to 4 miles) than I got from the previous battery when it was new.I wouldn’t hesitate to recommend this battery as a replacement for anyone looking for a new battery.If things change over the next year or two, I’ll edit this review with my experience.

Lasted over a year and 3000 miles.
Bought for an upgrade on my friend's Radrunner plus city ebike. After getting the right connectors,installed in original spot. Went from 32 miles of range to 75 miles easily. The old battery had 4 years and 7000 miles on it. He told me that was the best $500 upgrade that I could have made. After his thudbuster.
