Stackable solar battery main features:

[Capacity Free Expandable] - Stackable battery modules design, up to 16 modules parallel connected, 10-30kWh freely expandable.
[Long Lifepo4 Battery Lifespan] - Used the CATL Lithium battery cells, over 8000 cycles, 12-YEAR WARRANTY.
[20+ Inverters Compatible] - Stackable battery packs adapt to more than 20 inverter brands such as DEYE, Growatt, MAGEREVO, etc.
[Smart Display Screen] - Each stackable solar battery has a smart display, and push-button/touch screen free selection.
[High-Performance BMS System] - Overcharge, over-discharge, over current, short circuit, high and low-temperature protection functions.
[Simple, Flexible & Classic] - One of the most popular designs for LFP batteries, with rolling wheels and a carrying handle for easy moving and assembly.

Stackable Lithium Battery Specification:

• Harveypower's BMS system monitors and regulates battery charge and discharge status. The monitored battery characteristics include the detection of battery type, voltage, temperature, capacity, state of charge, power consumption, remaining operating time, charge cycles, and more.
• It can process and monitor up to 16 lithium-ion batteries at the same time, provide a battery balancing function, manage different batteries with the same charge and discharge requirements, and ensure the optimal utilization of the remaining energy in the battery.
• BMS Specification:

• Installation and Testing

• Our LiFePo4 battery packs are compatible with most inverter brands on the market, such as: PYLON,  SOFAR, GROWATT, VOLTRONIC, EAST, GOODWE, KELONG, INVTKSTAR, SRNE,  DEYE, MUST, SOLIS,  SCHNEIDER, VEICHI,  SMA, SACOLAR,  LUXPOWER, VICTRON,  STUDER.
• For inverters of other brands, corresponding debugging services can be provided according to the communication protocol.
• We have communication tests before and after battery module packing.
• In addition, we also have an energy storage battery with integrated inverter, which can solve all problems at one time.

• LED Display (Optional)

Build an LED display outside the product group to visualize the overall data and status of the battery pack. You can also DIY the operation functions of the display according to your needs.

• Self-heated Function (Optional)

• Bluetooth Function (Optional)

• State of Health (Optional)

Not only can we know whether the remaining available capacity of the battery can meet our demand for the total temporary power consumption, but also know when each single battery and battery pack needs to be replaced and repaired.

• More Optional

Yes, and the stackable battery should be stored in a cool, dry, ventilated environment, to avoid contact with fire and heat sources. Batteries should be stacked so that they're stable and won't be bumped, knocked over, or otherwise damaged.
The best storage temperature is 25 ± 5 ℃, the best humidity is 60 ± 15%.

The parallel connection is better, the parallel voltage remains unchanged, and capacity increases.
The voltage is higher current, heat is faster (the battery also has resistance), so the life is short, parallel connection through the two batteries is independent of the current, will not affect the life.
