Note:  Please use only a specified Lithium battery charger.  You may check this link for our Lithium charger -  https://www.ebay.com.au/itm/Lithium-Battery-Charger-Lithium-Iron-LiFePO4-10AMP/113990169588?hash=item1a8a57f3f4:g:MAoAAOSwJYVd3gcZ PLEASE READ INSTRUCTIONS CAREFULLY TO PROTECT YOUR BATTERY AND MAXIMIZE PERFORMANCE & LIFESPAN:

• Battery cells are brand new and only has 25% power.  First time charging will take longer to fully charge up to 14.6V.  Succeeding charges will be faster.
• Fully charge the battery before use. Maximum charge voltage is 14.6V.  A smart charger will indicate a green light once battery is fully charged.
• Using a battery charger with a specific Lithium charge algorithm is the best option for maximum performance and lifespan of any lithium battery.
• Battery can be charged using AC/DC, DC/DC and/or Solar Charger.
• Anderson plugs are 50A max capacity.  Both Anderson plugs can be used for input/output.  For current of more than 50A, please use the regular +/- terminals.
• Cigarette lighter socket has 10A maximum input & output.
• When storing for a long period, you may only charge the battery to 50%.  No need to fully charge it.

BWB Battery Cells Features:

• 1 cell has 100AH 3.2V (4 cells = 100AH 12.8V total)
• Bigger cells mean better safety and more power
• BMS (Battery Monitoring System)
  • The lithium battery monitoring system is a charge and discharge protection for the series lithium battery pack. When the battery is fully charged, the voltage difference between the individual cells can be ensured to be less than the set value (generally ±20 mV), and the battery cells of the battery pack can be uniformly charged, effectively improving the charging effect in the series charging mode. Simultaneously detecting the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature conditions of each single cell in the battery pack, protecting and extending the battery life; undervoltage protection prevents each battery cell from damage due to overdischarge during discharge.
• Safety Pressure Release Valve
  • Standard new safety technology for high quality batteries.
  • Prevents explosion caused by excessive internal pressures due to overcharging, short circuit, excessive temperature, battery deformation or puncture.
  • Safety valve on top if a very important for explosion-proof barrier. When pressure inside the battery is build up, the safety valve opens to avoid explosion.
• No Memory Effect
  • Rechargeable batteries work under conditions that are often not fully discharged, and the capacity will quickly fall below the rated capacity. This phenomenon is called the memory effect. There are memories like nickel-metal hydride and nickel-cadmium batteries, but lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be used with charging, no need to discharge and recharge.

Know more about BWB Lithium Iron Phosphate LiFePO4:

Lithium Iron Phosphate (LiFePO4) is a well-known lithium technology in Australia due to its wide use and suitability to a wide range of applications.

Characteristics of low price, high safety and good specific energy, make this a strong option for many applications.

It is considered as the safest, most enviro-friendly, Best/Excellent cycle life, most economical on long term costs and excellent temperature range from -200 C to 550 C.

 

Why LiFePO4?

Of all the lithium options available, there are several reasons why LiFePO4 has been selected as the ideal lithium technology for replacement of AGM DEEP CYCLE. The main reasons come down to its favourable characteristics when looking at the main applications where AGM DEEP CYCLE currently exist. These include:

• Similar voltage to AGM DEEP CYCLE (3.2V per cell x 4 = 12.8V) making them ideal for AGM DEEP CYCLE replacement.
• Safest form of the lithium technologies.
• Environmentally friendly –phosphate is not hazardous and so is friendly both to the environment and not a health risk.
• Wide temperature range.

 

Weight Comparison:

LifePO4 is one third weight of AGM DEEP CYCLE

• AGM Deep cycle 100AH – 29.5Kg
• LiFePO4 100AH– 10.5Kg
• Benefits
• Increases fuel efficiency
  • In caravan and boat applications, towing weight is reduced.
• Increases speed
  • In boat applications water speed can be increased.
• Reduction in overall weight
• Longer runtime

Weight has a large bearing on many applications, especially where towing or speed in involved, such and caravan and boating. Other applications including portable lighting and camera applications where the batteries need to be carried.

 

Greater Life Cycle:

Comparison

• Up to 6 time the cycle life
• AGM Deep cycle – 300 cycles @ 100% DoD
• LiFePO4 – 2000 cycles @ 100% DoD

Benefits

• Lower total cost of ownership (cost per kWh much lower over life of battery for LiFePO4)
• Reduction in replacement costs – replace the AGM up to 6 times before the LiFePO4 needs replacing

The greater cycle life means that the extra upfront cost of a LiFePO4 battery is more than made up for over the life use of the battery.    If being used daily, an AGM will need to be replaced approx. 6 times before the LiFePO4 needs replacing.

 

Flat Discharge Curve:

Comparison

• At 0.2C (20A) discharge
• AGM – drops below 12V after 1.5 hrs of runtime
• LiFePO4 – drops below 12V after approximately 4 hrs of runtime

Benefits

• More efficient use of battery capacity
• Power = Volts x Amps
• Once voltage starts to drop off, battery will need to supply higher amps to provide same amount of power
• Higher voltage is better for electronics
• Longer runtime for equipment
• Full use of capacity even at high discharge rate
• AGM @ 1C(100A) discharge = 50% Capacity
• LiFePO4 @ 1C discharge = 100% capacity

 

This feature is little known but is a strong advantage and it gives multiple benefits. With the flat discharge curve of LiFePO4, the terminal voltage holds above 12V for up to 85-90% capacity usage. Because of this, less amps are required in order to supply the same amount of power (P=VxA) and therefore the more efficient use of the capacity leads to longer runtime. The user will also not notice the slowing down of the device (golf cart for example) earlier.

Along with this the effect of Peukert’s law is much less significant with lithium than that of AGM. This results in having available a large percentage of the capacity of the battery no matter what the discharge rate. At 1C (or 100A discharge for 100AH battery) the LiFePO4 option will still give you 100AH vs only 50AH for AGM.

 

Increased Use of Capacity:

Comparison

• AGM recommended DoD = 50%
  • LiFePO4 recommended DoD = 80%
• AGM Deep cycle – 100AH x 50% = 50Ah usable
  • LiFePO4 – 100Ah x 80% = 80Ah
• Difference = 30Ah or 60% more capacity usage

Benefits

• Increased runtime or smaller capacity battery for replacement

The increased use of the available capacity means the user can either obtain up to 60% more runtime from the same capacity option in LiFePO4, or alternatively opt for a smaller capacity LiFePO4 battery while still achieving the same runtime as the larger capacity AGM.

 

Greater Charge Efficiency:

Comparison

• AGM – Full charge takes approx. 8 hours
  • LiFePO4 – Full charge can be as low as 2 hrs

Benefits

• Battery charged and ready to be used again more quickly

Another strong benefit in many applications. Due to the lower internal resistance among other factors, LiFePO4 can accept charge at a much great rate than AGM. This allows them to be charged and ready to use much faster, leading to many benefits.

 

Low Self Discharge Rate:

Comparison

• AGM – Discharge to 80% SOC after 4 months
  • LiFePO4 – Discharge to 80% after 8 months

 Benefits

• Can be left in storage for a longer period

This feature is a big one for the recreational vehicles which may only be used for a couple of months a year before going into storage for the rest of the year such as caravans, boats, motorcycles and Jet Skis etc. Along with this point, LiFePO4 doesn’t calcify and so even after being left for extended periods of time, the battery is less likely to be permanently damaged. A LiFePO4 battery is not harmed by not being left in storage in a fully charged state.
