○ Working mode

Charging mode

When a charger was detected, and the charger voltage is 0.5V+ more than the battery voltage,BMS will turn on the charging MOSFET.And when the

charging current reaches the effective charging current value,enters charging mode.

Discharging mode

When a loads was detected, and the discharging current reaches the effective

discharging current value, BMS enters discharging mode.

Standby mode

When the BMS not in charging mode, nor discharging mode, it enters standby mode.

Power off mode

The BMS enters the shutdown mode after 48 hours of normal standby,battery triggering under voltage protection, key shutdown or external switch

shutdown.

Wake-up conditions of shutdown mode:

1) Charge activation.

2) 48V voltage active.

3) Press key to start.

03 Core Advantages

This wheeled energy storage battery needs no wall mounting and can be moved by one person for homes and shops.

Built with 16S1P Grade-A LFP cells and active balance board, it reaches 8,000 cycles at 80% DOD with great cell consistency.

It features full hardware protection, CAN/RS485, Bluetooth and cloud monitoring,

supporting up to 16 parallel units for India's hot, frequently blackout grids.

Pre-assembled with full parts, it works with mainstream hybrid inverters.

Full certifications and OEM/ODM are provided for Indian residential & small commercial energy storage.

1.Luggage-style Movable Appearance, Zero Barriers to Installation & Placement

Equipped with an integrated telescopic pull rod and silent universal casters, this minimalist floor-standing unit differs from traditional wall-mounted energy storage batteries. It can be easily pushed and moved by one person without wall drilling. Featuring a matte minimalist cabinet and front touch screen, it can be freely placed indoors, in shops or for temporary outdoor power supply, perfectly fitting flexible deployment for various Indian housing types.

2. 16S1P Single-Cell Architecture + High-Power Active Balancing BMS for Superior Lifespan & Cell Consistency

It adopts brand-new Grade-A 3.2V 280Ah LiFePO4 prismatic cells with a 16-series single-parallel design, eliminating heating risks from excessive welding points. Built-in high-power active balancing board enables continuous cell equalization during charging and standby for 24 hours. It delivers up to 8,000 cycles at 80% DOD, while cell voltage difference is controlled within 30mV long-term, drastically reducing after-sales capacity degradation failures.

3. Full-Range Multi-Protection & Dual Communication System, Adapted to Harsh Indian Grid Conditions

Comprehensive hardware protections including overvoltage, undervoltage, overcurrent, short circuit, low/high temperature and MOS overtemperature are integrated, with multiple temperature sensors for real-time monitoring. Standard CAN & RS485 dual communication, Bluetooth local commissioning and cloud remote monitoring are supported, with storage capacity for up to 500 fault logs. It stably operates under India's high-temperature, unstable grid and frequent power outages, and allows parallel connection of up to 16 units for capacity expansion.

4.Standardized All-In-One Unit, One-Stop Match for Residential Solar Storage Scenarios

This 14.336kWh standard residential energy storage unit supports rated 100A and peak 200A charge/discharge current, compatible with mainstream hybrid inverters on the market.
