Freedom Won 12v wiring configuration - Suitable for parallel and series configurations using the same a/h (model and type) and same brand.
Parallel Configuration: Can be connected in parallel to unlimited numbers provided that the voltages of all units are similar to each other - within a delta of 0,06V prior to being connected.
Series Configuration: Can be connected in sets of: 2 (24V) 26V nominal voltage, 3 (36V) 39V nominal voltage or 4 (48V) 52V nominal voltage. Prior to connection connect each unit in parallel and charge fully to 14,2V then reconfigure into series connection.
If additional capacity is required multiple units can be connected in parallel to form a parallel group, then up to four of these groups can be connected in series. Each parallel group must contain the same number of units of the same model and type and each unit in a parallel group must be connected with all positive and negative poles connected to each other respectively.
NB - caution: Separate parallel strings that are only connected at the pack negative and positive ends are not recommended.
FAQ's and benefits of this technology:
Charger type: The chemistry is so stable that LiFePO4 batteries will accept a charge from a lead-acid configured charger.
Technology: What is the difference between lithium ion and lithium iron phosphate batteries?
A lithium-iron battery is also a rechargeable type of battery but made with lithium iron phosphate (LiFePO4) as the cathode material. While lithium-iron is a newer version in the lithium battery family, its anodes are also made up of carbon in batteries. Phosphate chemistry also offers a longer cycle life.
Expected Life Cycle: In off-grid systems is over 15 years, in grid-connected backup installations with occasional cycling is more then 20 years. The end of life is defined by when the cells contain 60% of their Beginning of Life (BoL) capacity. LiFePO4 does not deteriorate from standing unused and self-discharge is extremely low making it an ideal battery for backup systems such as load-shedding, camping applications etc.
Higher initial cost: Long term much cheaper than your average deep cycle batteries - 10 times the number of cycles more and as much as 5 times that of the more robust single cell flooded lead acid types.
The technology is about one quarter of the weight of lead acid types
Sustained high power output is possible without voltage drop or over heating
Discharge efficiency is better than 98%, average % for lead acid is around 65%
Charging time is much faster than lead acid, 2 hour standard, 45 min quick whereas lead acid typically should not be done in less than 5 hours.
Wide Temperature Range: 20°C~60°C.
Safety: Lithium Iron Phosphate Chemistry eliminates the risk of explosion or combustion due to high impact, over charging or short circuit situation.
Increased Flexibility: Modular design enables deployment of up to four batteries in series and up to eight batteries in parallel.
Applications: Camping, Caravans, Boats, Yachts, 4x4, Aux Batteries, Alarms, Gate Motors, Electric Fences, backup eg load shedding, UPS - etc.
Manufactured in South Africa.
Warranty: Freedom Won lithium iron phosphate 12V batteries is supported by an extensive product guarantee, the battery will achieve at least a 5 year service life in any application for which it is intended without loss in performance.
Performance guarantee = the battery is guaranteed to retain more than 70% of its new capacity after 5 years and that it will still be able to meet the maximum current levels as stipulated on the data sheet, T&C's applicable.
Copy of warranty will be sent to you with your invoice.
Order lead time: Normally around 4 weeks. If you need the battery/batteries sooner than that please use Q&A so that I can check with supplier if they can supply the order before then.
