1000ah Lifepo4 Winston Battery Cells

The 1000ah lifepo4 winston battery cells in solaroidenergy are designed for various data centers and large capacity requirement. The replacement cost of the fully charged 1000AH Forever Batteries is equivalent to around 40,000 traditional lead-acid batteries. The battery cell features high discharge level, low self-discharge rate and long cycle life. The new technology lithium-polymer batteries are safe and reliable, with much easier recycling process than traditional lead acid batteries.

The 1000ah lifepo4 battery pack contains 30 cells. This battery pack is the most popular in our powerwall range, with low current drain and long cycle life, it is ideal for use in solar energy storage systems. We also have 1000ah Lifepo4 Battery Cells available in individual cells as well as a Full Set.

High power lithium cell, original Winston Battery product with LiFePO4 (LiFeYPO4) technology. Capacity: 1000Ah, size: 356x560x130 mm, weight: 41 kg. Model: WB-LYP1000AHC(A)

Initial, first time charging

Cells are precharged from manufacturer to conservation charge (usually 30-50%).
The cells have to be charged with low current before the first use.
The first charge should not exceed 0.5 C – eg for 1000Ah cell is 500A.
For initial charging of multiple cells, connect them in parallel and the charger outputs should be connected to both ends of the parallel rows of cells, exactly as it is described here:

We recommend to use chargers specially made for LiFePO4 cells First charge and initial balancing of the whole pack is important step towards long lifetime.

Alternatively you can use regulated (Laboratory) Power supply as initial charge tool. Short description how to proceed.

Balancing and protection

Demonstration video of BMS123 Smart Gen2 assembly

Important part of each battery pack is balancing and protection electronic. Most frequent solution is BMS123 Smart Gen3. This Advanced solution for battery monitoring and management of LiFePO4 cells support Bluetooth connection with your phone, iPad, tablet or other device. Free Android and iOS application included.

SBM is simple solution offering basic protection, diagram shows 16 cell version connected with charger and fuses.

Connecting the cells

Winston produce cells with easy to assemble square shape, terminals are made for screws allowing simple installation with spanner.

Interconnection between cells is important part of any battery pack. Original copper connectors are made of several thin layers for ideal flexibility and conductivity.
Make sure to clean oxidation from both, terminals and connectors (with Sandpaper or similar) before assembly. Oxided contacts may have very high resistance and cause unbalancing of the battery.

Plastic caps are cheap solution to prevent unwanted shortcuts and for easy plus and minus marking (red and black colors are available).
