BatChat Super Group Chat Guide - Up to 50K Members | BatChatHub

TL;DR

BatChat (蝙蝠聊天) supports super group chats (万人群聊) with up to 50,000 members per group. Each user can join up to 1,100 groups with no join restrictions. Groups feature anonymous chat (匿名聊天), polling (投票), member protection, and admin moderation tools. Groups are discoverable by keyword search. The feature is available to all users, though VIP and SVIP members get higher limits for friends and groups.

What Is BatChat Super Group Chat?

BatChat’s super group chat, called 万人群聊 (ten-thousand-person group chat) in Chinese, is a large-scale messaging feature that allows up to 50,000 members in a single group. This puts it in the same capacity tier as Telegram’s supergroups and far exceeds WeChat’s 500-member group limit.

The feature is built on the same end-to-end encryption foundation as BatChat’s one-on-one chats. Group messages are encrypted before leaving the sender’s device, transmitted through BatChat’s servers, and decrypted on each member’s device. The encryption model uses asymmetric encryption and the Double Ratchet protocol (双棘轮加密) as documented on BatChat’s official safety page.

BatChat’s official materials state the app has “tens of millions of users” (数千万用户), and the super group feature is positioned as a tool for networking, job hunting, interest communities, and business collaboration.

How to Create a BatChat Group

Creating a standard group

1. Open BatChat and tap the ”+” button on the main chat list
2. Select “创建群聊” (Create Group Chat)
3. Select contacts from your friend list to add as initial members
4. Set a group name and optionally a group description
5. Tap create

Creating a discoverable super group

For groups intended to grow beyond your immediate contact list:

1. Create the group using the steps above
2. After creation, open the group settings (tap the group name at the top)
3. Enable group discoverability so other users can find it via search
4. Set appropriate member permissions (who can post, who can invite)

The group discovery system works through keyword search. Users navigate to “加好友/群” (Add Friends/Groups), type in keywords, and BatChat’s system returns relevant group recommendations. Tapping the join button on the right side of a search result adds the user directly.

BatChat Group Member Limits

The member capacity hierarchy in BatChat:

• Maximum per group: 50,000 members
• Maximum groups per user: 1,100 groups (up to 1,000 for SVIP11)
• Join restrictions: None — users can freely join any discoverable group

The per-user group limit scales with membership tier:

Tier	Max Groups	Max Friends
Free user	Base limit	Base limit
SVIP11	1,000 groups	9,500 friends
Standard VIP	Lower than SVIP	Lower than SVIP

The exact limits for free and standard VIP users are not publicly documented by BatChat — the developer publishes SVIP-tier numbers in its update announcements (such as the v3.4.9 SVIP11 announcement on Baidu Tieba in June 2025) but does not provide a complete comparison table for all tiers. Users report that free accounts can join at least several hundred groups, which is sufficient for most use cases.

Anonymous Chat in Groups

One of BatChat’s distinctive group features is anonymous chat (匿名聊天). When enabled in a group, members can post messages without revealing their identity to other group members.

How anonymous chat works

• Members who post anonymously appear with a generic identifier rather than their username or profile
• Other group members cannot trace the anonymous message back to a specific account through the normal interface
• Group admins may have access to moderation tools that can identify anonymous posters in certain contexts (this varies by BatChat version)

Use cases for anonymous chat

Anonymous chat is useful in scenarios where participants need to speak freely without social pressure:

• Workplace feedback groups: Employees can raise issues without fear of management retaliation
• Support groups: Members can share personal experiences without attaching their real identity
• Community discussions: Sensitive topics (health, legal, financial) where anonymity encourages participation
• Whistleblowing: Reporting misconduct within an organization

Limitations

Anonymous chat is a group-level setting, not a per-message setting. The group admin decides whether anonymous posting is available. Not all groups enable this feature. When it is enabled, the group admin retains moderation authority and can remove anonymous posts that violate group rules.

Polls in BatChat Groups

BatChat groups include a built-in polling feature (投票功能) that allows group admins and members to create polls for quick decision-making or opinion gathering.

Creating a poll

1. Open the group chat
2. Tap the ”+” extension menu next to the input field
3. Select the poll option
4. Enter your question and answer choices
5. Configure poll settings (single choice vs. multiple choice, anonymous voting, time limit)
6. Post the poll to the group

Practical applications

• Community decisions: What time to schedule an event, which restaurant to choose
• Feedback collection: Quick surveys on group direction or content preferences
• Market research: Business groups polling members about product preferences
• Event planning: Determining attendance and preferences for group activities

Polls can be set to anonymous mode, where individual votes are not visible to other members, only the aggregate results. This encourages honest participation on sensitive topics.

Admin Tools and Moderation

BatChat provides a layered admin system for group management. Groups have a group owner (群主) who has full control, and can appoint administrators (管理员) with a subset of moderation powers.

Group owner capabilities

• Appoint and remove administrators
• Set group rules and description
• Configure member permissions (who can post, who can invite others)
• Enable or disable anonymous chat
• Delete any message in the group
• Remove and ban members
• Dissolve the group entirely

Admin capabilities

• Delete messages that violate group rules
• Remove members who break rules
• Pin important messages or announcements (精华消息)
• Set group to-do items (群待办) for event tracking
• Manage member permission combinations for different roles

Member protection

BatChat groups include a “member protection” (群成员保护) feature. When enabled, this restricts what actions non-admin members can take against each other — for example, preventing members from viewing each other’s profiles or adding each other as friends without mutual consent. This is particularly relevant in large groups where privacy between members matters.

Permission combinations

As documented in BatChat’s v2.5.0 update notes, group admins can now configure multiple permission combinations for different member roles. This means you can create tiers within a group:

• Full members: Can post, react, participate in polls
• Restricted members: Can only read, cannot post
• Moderators: Can delete messages and warn members
• VIP members: Custom permissions set by the group owner

This granular control makes BatChat groups suitable for structured communities like online courses, project teams, and professional associations.

Finding and Joining Groups

The group discovery system is one of BatChat’s most practical features for new users. Here is how it works:

1. Open BatChat’s main interface
2. Navigate to “加好友/群” (Add Friends/Groups)
3. In the search bar, enter keywords related to the type of group you want (e.g., “technology”, “job hunting”, “gaming”)
4. BatChat’s system returns a list of relevant groups based on the keywords
5. Each result shows the group name, member count, and a brief description
6. Tap the join button on the right side of the listing

There are no caps on how many groups a user can join within the system limit (1,100). The barrier to entry is intentionally low — unlike some platforms that require invitation links or admin approval, most BatChat groups allow direct entry through search.

Tips for finding quality groups

• Search in Chinese for more results — the majority of BatChat’s user base communicates in Chinese
• Check the member count — groups with very few members may be inactive, while groups near the 50,000 cap may be noisy
• Read the group description before joining to understand the group’s purpose and rules

Group Chat Security Features

All BatChat groups inherit the platform’s security model:

• End-to-end encryption: Messages are encrypted on the sender’s device and decrypted only on each recipient’s device
• Zero server storage: BatChat states that message content is not stored on servers (服务器零数据存储)
• Screenshot protection: The app attempts to block screenshots and screen recording within group chats
• Disappearing messages: Can be enabled in group chats just like one-on-one chats (3 seconds to 30 minutes)

The anonymous chat feature adds another privacy layer — even within an encrypted group, your identity is not necessarily visible to other members when posting anonymously.

Security considerations for large groups

With 50,000 potential members, group security requires different thinking than small-group privacy:

• More potential attack surface: More members means more devices that could be compromised
• Trust is lower: In a group of strangers, the incentive structure for leaking information is different than in a small trusted circle
• Admin visibility: Group admins have moderation powers that can potentially identify anonymous posters depending on the version and configuration

For genuinely sensitive discussions, a smaller group with vetted members is more secure than a large public group, regardless of the encryption technology used.

Common Issues with Large Groups

Group is too noisy

In large groups (thousands of members), message volume can be overwhelming. Mitigation strategies:

• Use BatChat’s message muting for specific groups
• Enable “Do Not Disturb” for high-volume groups while staying subscribed
• Group admins can restrict posting permissions to reduce noise
• Pin important announcements so they are not buried in the message stream

Cannot find a group through search

• Try broader keywords — “科技” instead of “Python programming”
• Check that the group owner has enabled discoverability for the group
• Some groups are invite-only and do not appear in search results

Group admin is inactive

There is no automated mechanism for transferring ownership of an inactive group. If the original group owner stops using BatChat, the group may become unmoderated. This is a limitation of the current system.
