3.2V Lithium Iron Phosphate 6 Ah
6000 mAh – 3000+ recharge cycles
Charge to 3.65 Volts full charge
Stop use at 2.9 V per cell.
Typical resting voltage is 3.33 volts during a 60% state of charge.
Maximum recommended continuous charge and discharge rate is 2C.
Perfect for anything that demands a lot of power, from solar backup and storage to EV’s and aircraft.
LiFePO4 cells are large but strong and easy to handle. You can weld or solder them together to make your own battery pack. 4 cells connected in series will make a 12 Volt 6 Ah battery pack that can be used with regular lead acid chargers.
Some people use these packs without any BMS. As long as you check the voltage regularly, this setup is simple, reliable, and can last a long time as long as you don’t over discharge the battery. A 4S LFP pack will have a full charge voltage of 14.6 volts, it should be floated at 13.3 volts, and will cut off around 11 volts.
LFP cells maintain a much more constant voltage along the discharge cycle, so the volts only drop a little as the cell depletes. This is great as it provides power stability without need of regulators.
LFP is much safer than Li-Ion and last 3000 recharge cycles instead of the 300 for Li-Ion.
Image 1/. We tested at 2A discharge for 56:38:18Hr down to 10.60V from 13.56v
Image 3/. Produced 105Ah and 1361.3Wh
we set the cut off at 10.6vdc
Image 4/. 24Hr self returned to 11.40vdc resting
100AH Lithium Iron
This battery pack is used, untested, other than we discharged it and show you the results. It is sold for the, cells and BMS value only. For the use of the Solar/DIY/Hobbyist/Power Wall enthusiast project builder and intended to be stripped out and tested by the end user. Then used to support the power pack builds of the users choise.
We do our best to sort out any swollen bad packs so it is likely that most of these cells will take a charge and cycle just fine. Our shipping calculater is designed to take into consideration weight and carton size with a max weight of 25Kg, however due to size and shape of the the max number of packs is limited by weight, all this has been added into our NEW calculater and New shipping contracts negotiated to give you the best possible Shipping price to your destination.
We do everything we can to supply you what you ask for but we cant see inside the power packs so you may end up with an odd mis-match keep them to one side and we’ll fix it up with your next order. However nearly every time the cell is the same value just a different Brand mostly all grade “A”cells.
Manufacturers Data Sheets provide an excellent insight into the cells design capabilities and parameters and Google is a great tool to find them. Just look for the cell data on the cell wrapping and search accordingly. The images display an example of what the the power packs look like
The health of a battery is based on three fundamental attributes:
Capacity, the ability to store energy. Capacity is the leading health indicator of a battery Internal resistance, the ability to deliver current Self-discharge, indicator of the mechanical integrity When making these measurements you must consider type and accuracy of equipment used, as well as ambient and battery temperature. Our combined cell count over our range of products goes well beyond 76k refurbished cells. Free Local pickup is available. We will also combine postage with other items so as to reduce shipping costs. Due to the nature of our Lithium products we offer no guarantees as to their use by the end users skill set and do not warrant there end use in any way.
We have loads of unlisted stock so if you need cells you dont see, just ask!
