Reention Downtube Battery Packs
Reention makes popular battery packs used by many different bike companies for their sleek, semi-integrated downtube design offering high capacity. They come in a variety of voltages and capacities. We can rebuild them all, often time upgrading your capacity to give you longer ride time!

These battery packs can be found on E-Joe, Volt Bike, Samson, Juiced, Surface 604, Smartmotion and FLX among others. Even if we don't have an online ordering link, contact us and we'll help you out. It doesn't matter if it's a 36V or 48V pack or what capacity it was to begin with.
All of our rebuilds are backed by our 12 month warranty. So if you're ready to get back on the road, send us your battery and charger with our Battery Intake Form and let us rebuild your battery.
I have a reention 48v 11amp can you upgrade to 52v and higher amps??
@Tyler – We do not sell keys for the mounting bracket. We only have the battery cases themselves.
do you sell keys for retention 48v down tube dorado?
@Richard – Yes, we can build the battery for you. Pricing depends on the size of the battery. We’ll be in touch with more info.
I ride a Populo Sport With a 36v7ah battery. If I can get a replacement case from Populo (they no longer have a replacement batt), can you rebuild it with increased AH’s and what would be the ‘ballpark’ cost?
Thanks!
