Honda has jumped into the swappable battery game in Tokyo and may partner with Hero to set up the same system in Indian cities. Here is the story: https://www.revzilla.com/common-tread/honda-is-officially-in-the-swappable-battery-game-for-electric-motorcycles

It's unclear whether this is the same swap system that Honda is supposed to be standardizing on as part of the SBMC industry consortium (founded in 2019 by the Japanese Big Four, then Piaggio & KTM joined, and now has 21 members (https://electrek.co/2022/09/15/swappable-battery-motorcycle-consortium-grows-to-21-members/));
SBMC batteries are 48V and up to 2kWh, intended for 2PWs with up to 11kW of power;

these Honda batteries for the project with Hero are 50V 1.3kWh

and if it's not the identical system, why not (publications are too lazy to shoot off an email, and I'm disappointed seeing Revzilla succumb, and just republish a PR)?
In any case, these swappable batteries aren't relevant for full-size bikes; they're for scooters and barely for 125cc-equivalent short-range commuters, if you use 2-3 in a single bike.

The SBMC has not released specifications for their standard yet. Sounds like Honda (although a member) is not waiting around for till they do.

However based on the spec sheet Honda provided it looks to meet the parameters from the EBMC webpage.
- Low voltage vehicles (48V) - Honda quotes 50V but it's unclear if that is nominal or the max operating voltage.
- Weight below 12 kg - Honda quotes 10.3kg
- Battery energy up to 2 kW/h - Honda quotes 1.31kWh (less than 2)
Since Honda is a core member of EBMC I would suspect they might try to steer the standard towards their pack design.

Thanks Demoni!
It actually hadn't occurred to me that SBMC hadn't actually released their standard yet... it's been over 3.5 years since the consortium was set up, and it shouldn't be that complicated to settle on the major details. This ain't rocket science. Gogoro has been doing this (for the same application) for years, and Piaggio launched a swappable battery system for the BEV version of their 3-person 3-wheeled riksha in India with larger 4.5kWh batteries (up to 3 can be inserted):

SBMC could allow some variance in voltage to support different chemistries, since we're talking scooters & commuters here, not bleeding edge performance e-motorcycles where every component must be optimized for max output and/or efficiency. The BMS would use a protocol to transmit the specific parameters to the vehicle.
