Free Shipping- Battery Box 51.2V Lifepo4 Power Bank Built In BMS No Active Balancer

The only difference between it and the 3.0 version is that it does not have an active balancer. Of course, if you want active balancer, you can install it by yourself. There is space reserved for active balancer inside.

Why we need a battery pack system?

1. Home Energy Freedom Even After Major Weather Events
2. Provides Day-to-day Savings and Protection from Outages.
3. Home Power Provides Visibility, Control & Energy Freedom
4. Decrease your reliance on the grid.

It can hold 16 280AH-320AH battery units, and you can DIY according to your needs. We also provide the most commonly selected solutions——280AH  for customers, and can ship them to your door together.

This battery pack system, is applicable both for residential and commercial energy storage system, accompany with Smart BMS. Each pack support 16packs in parallel to easily expand capacity. Do not mix parallel the battery packs of different brands or model

FUNCTION

Battery voltage calculation: 16 battery voltage sampling test, deviation ± 20mV

Battery and ambient temperature detection: 4 battery temperature sensors, 1 ambient temperature sensor, 1 MOS temperature sensor, deviation ± 2 ℃. 

Battery capacity and cycle times: complete a complete charging, discharging cycle to set the actual capacity. Monitor the remaining capacity of the battery with the capacity estimation accuracy within 5% deviation. In addition, the charging and discharging cycle time and the complete charging and discharging cycle time can be configured.

Smart cell balance: charging and static balance strategies can be flexibly set to effectively extend the service life.

Communication interface: PC or intelligent front-end can monitor battery data, control operation and set parameters through telemetry, remote signaling, remote adjustment, remote control and other commands. The communication protocol meets the requirements of YD/T 1363.3 and realizes cascade communication

Historical data recording, saving and reading: when the battery is abnormal, record and save real-time battery status and alarm information. At present, up to 500 historical fault data can be stored.

Battery management system parameter setting: battery management system parameters, including cell battery over voltage/under voltage, battery total voltage over voltage/under voltage, charge and discharge over current, battery high/low temperature, battery capacity, working mode, charge and discharge limit current, can be set in the battery monitoring system. 

Working mode: charging and discharging current limiting, constant voltage output, direct output and other working modes can be set in the monitoring system

Multiple protection functions: hardware protection, battery protection, high and low temperature protection, output short circuit protection, etc.
