High-Efficiency 100A BMS with 3A Active Equalization
Active balancing means you retain more usable capacity over the life of the battery pack, accept faster and fuller charging without hitting early cutoffs, and experience slower capacity fade so the system delivers steady performance year after year.
Without active balancing, individual cells drift to different States of Charge (SoC) over repeated cycles, which means the battery’s usable energy is effectively capped by the weakest cell. This mismatch forces earlier charge or discharge cutoffs, limits safe charge rates, reduces usable capacity, and accelerates overall ageing.
Touchable LCD screen, Easy to Check Everything
- ①The main interface displays the function options, including battery pack information, cell voltage, temperature, BMS alarm status, charge and discharge curve chart, setting and system information.
- ②The Pack screen shows the battery's voltage, current, SOC, temperature and so on.
- ③The cell screen displays all the voltages and temperatures of the single cells.
- ④The alarm screen indicates the battery alarms, faults and other abnormal information.
- ⑤There is also a chart to show the voltage, current and the SOC curve of the battery pack during operation.
- ⑥With this LCD screen, you can set the communication protocol between the battery and the inverter, the language, and easily check the product information.
Multiple Interfaces, Synchronous Communication
This WattCycle 48V 100Ah Wall-mounted Solar Batteries have three communication interfaces: a CAN (Controller Area Network) interface with strong anti-interference ability, which helps you transmit key battery data; an RS485 interface suitable for medium and long distance transmission, which helps you remotely monitor your battery energy system; and an RS232 interface that can be used for maintenance and debugging of battery energy systems, which helps you configure battery parameters and read operating data.
The three communication interfaces of WattCycle batteries have extremely high compatibility and can be connected to a variety of inverters, such as Victron, Deye, Growatt, GoodWe, SOFAR, SMA, and Pylontech.
Whether you are looking for reliable energy for a data center, or thinking of upgrading your home energy system to LiFePO4 batteries, WattCycle 48V 100Ah wall-mounted solar battery is always a wise choice. Up to 20 batteries can be connected in parallel to achieve Max 102,4 kWh usable energy, which can highly expand the capacity of your power system, letting you have no worries for off-grid living energy shortage or blackouts in your apartment.
