100BALANCE 100A 4-8S CAN SmartActive Balance BMS Set - WiFi + LCD

In this review of the 100BALANCE 100A SmartActive Balance BMS set, the bottom line is simple: it is aimed at DIY battery pack builders and small electric vehicle hobbyists who need robust multi-channel monitoring and safety for 4-8s lithium packs. The set combines a 100A balance BMS with a 3.0in LCD display and WiFi/Bluetooth connectivity to let a single pack be monitored locally and remotely without switching connectors. The reviewer found the combination of built-in Bluetooth, CAN/RS485/UART and WiFi communications particularly valuable for real-time monitoring and the comprehensive protection suite reassuring for safety-focused projects.

Key Features

• 100A protection: Provides continuous current monitoring and protection up to 100A for medium-capacity packs, helping prevent overcurrent events.
• Simultaneous display and app: WiFi and the LCD display work at the same time to show identical BMS information on the app and on the local screen without changing connectors.
• Multi-channel communications: Built-in Bluetooth and support for RS485, CAN, UART and WIFI allow flexible integration with telemetry and external controllers.
• Comprehensive safety: Basic protections such as overcharge, overdischarge, overcurrent, short circuit and temperature protection combine with extra measures like pre-charge and parallel protection.
• Display options: The 3.0in LCD included shows one BMS at a time on screen plainly, while a larger 4.3in touch display (sold separately) supports pack parallel connection and switching between multiple BMS units.
• App support: The BalanceBMS app on iOS and Android makes remote monitoring straightforward for users who want phone access to cell and pack status.

Who It's For

The 100BALANCE 100A BMS set is best for hobbyists, e-bike or small EV builders, and technicians assembling 4-8s lithium packs who need integrated monitoring and layered protection. Its networking options appeal to users integrating packs into systems that rely on CAN, RS485 or WiFi telemetry.

Users who need very high continuous currents beyond 100A, or those who require an out-of-the-box multi-BMS dashboard without manual switching, should consider alternative solutions or the 4.3in touch display option for multi-pack switching capability.

Pros & Cons

Pros

• Comprehensive protection set covers overcharge, overdischarge, overcurrent and temperature management for safer operation.
• WiFi and LCD display can show the same BMS information simultaneously, making monitoring convenient both locally and remotely.
• Multiple communication channels including Bluetooth, RS485, CAN and UART provide excellent integration flexibility.

Cons

• The included 3.0in LCD supports only one BMS display at a time, so multi-BMS setups require the 4.3in touch display or manual switching.

Specifications

Our Verdict
