Overview
Romeo / Juliet Battery Pack
The replacement and spare battery for Eahora's Romeo and Juliet lines, and the capacities are absurd in the best way: 60Ah, 70Ah, and 80Ah packs, up to 60V 80Ah for the Romeo Pro III and Romeo Ultra II. That is roughly 4,800Wh, more than double what most ebike brands sell as their large option.
Ordering takes care. Eahora splits variants by model, year, and even the number of battery mounting holes (2023 frames use 7, 2024 use 6), and warns that Juliet III 48V and 52V packs are not interchangeable. Match the variant to the exact bike or it will not mount.
Each pack has a waterproof hard shell and a 5V USB port for charging your phone off the bike.
Why this one
Our take
Highest-ticket accessory in the entire Eahora catalog and it fits 8 of the 15 Eahora bikes we carry. Range anxiety sells second batteries, and nobody else sells an 80Ah pack.
