LifePo4 BATTERY ADVANTAGES
Lithium iron phosphate batteries (LiFePO4 or LFP) offer lots of benefits compared to lead-acid batteries and other lithium batteries. Longer life span, no maintenance, extremely safe, lightweight, improved discharge and charge efficiency, just to name a few. LiFePO4 batteries are not the cheapest in the market, but due to a long life span and zero maintenance, it’s the best investment you can make over time.
LiFePO4 has many advantages over other lithium-ion battery designs and older lead-acid (LA) batteries. They weigh less, they require zero maintenance, they have better charge and discharge characteristics and they have a much longer life, making them one of the best value electric propulsion solutions for boats.
Other key benefits of LiFePO4 include high current rating, longer cycle life, zero leak and fire risk and a tolerance to sub-optimal charging and discharging cycles.
Why are LiFePO4 batteries so efficient? In a like-for-like comparison with systems that use other lithium ion or lead acid batteries, lithium iron phosphate (LiFePO4) offers a superior combination of characteristics, especially for propulsion in leisure boats and small commercial vessels.
LiFePO4 battery designs have improved discharge and charge efficiency and the ability to deep cycle while maintaining performance, something that LA chemistries and other designs of lithium battery cannot match.
Better Performance from the keel up
The combination of long life, slow self-discharge rates and low weight with high battery capacity make lithium iron phosphate batteries (LiFePO4) the ideal starting point for electric leisure boats.
Faster Charging process
Battery charging time for LiFePO4 batteries is quicker than for lead acid or other lithium batteries, Typically LiFePO4 units have four times the energy density and charge five times faster than lead acid batteries.
Cycle life for a LiFePO4 battery is up to five times the cycle life of some lithium ion batteries, often reaching up to 5000 cycles without any significant drop in performance.
LiFePO4 battery packs can also run down to 100% DOD (depth of discharge) without any damage or drop in performance.
LifePo4 HAS A LONG LIFESPAN
Totlpower lithium iron phosphate batteries live up to 5000 cycles at 80 percent depth of discharge, without decreasing in performance. The average lifetime of lead-acid batteries is just two years.
NO ACTIVE MAINTENANCE
Totlpower lithium iron phosphate batteries (LiFePO4) don’t require active maintenance to extend their service life. Also, the batteries show no memory effects and due to low self-discharge (<3% per month), you can store them for a longer period of time. Lead-acid batteries need special maintenance. If not their life span will be decreased even more.
Totlpower lithium iron phosphate batteries (LiFePO4) offer high power density which causes lithium batteries to be relatively small and light. Compared to lead-acid batteries lithium provides great energy density and are at least half the mass. Go for lithium if you want to reduce concerns about battery weight and size!
HIGH DISCHARGE RATES
Totlpower lithium iron phosphate batteries are specially developed to handle high discharge currents. You can start easily heavy engines or use several electrical devices at the same time on your boat or RV.
Environmentally Friendly to make
Unlike a lithium battery and lead acid batteries, LiFePO4 batteries do not contain toxic, heavy or rare earth metals like cobalt, nickel or lead. LiFePO4 is composed of common materials like graphite, iron and copper.
These materials are cheaper to source, more abundant and also require less energy to mine and process, representing a greener choice for boat owners looking for green electric boat propulsion solutions.
Environmentally Friendly after use
So, lithium iron phosphate batteries are greener to make, but they also present a much lower environmental risk throughout their working life compared to other lithium batteries.
The phosphate salts used in LFP batteries are far less soluble than the metal oxides used in other lithium batteries. This makes it much less likely for LiFePO4 units to leach chemicals into the environment, even if the battery is improperly discarded.
The same cannot be said for LA batteries whose structure can degrade over time, leading to poisonous chemical leakage.
Unlike other battery chemistries, LiFePO4 battery packs are also easy to recycle at the end of their working life.
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. Memory like nickel-metal hydride and nickel-cadmium batteries, but the lifepo4 battery does not have this phenomenon, no matter what state the battery is in, it can be used with the charge, no need to discharge and recharge.
Here are the benefits of Lithium iron phosphate Lifepo4 batteries in a nutshell:
- High discharging and charging efficiency: Charge and discharge efficiency can reach as much as 90%, compared to only 80% for lead-acid batteries.
- High safety performance: Stable construction that doesn’t decompose, heat up or collapse like other lithium ion battery materials.
- Long battery life cycle: Has a life cycle of over 2,000 times compared to 300 times for long-life lead acid batteries. Theoretically, it could last between 7 and 8 years.
- Performs well at temperatures: The LiFiPO4 battery performs well at extremes of temperature with an operating range of -20C to +75C. Heating peak can reach 350°C-500°C
- High capacity battery: Compared to lead acid batteries and other lithium-ion batteries, the LiFiPO4 battery has a much larger capacity of between 5AH and 1000AH.
- Zero memory effect: LiFiPO4 batteries have no memory effect, unlike other rechargeable batteries.
- Lightweight: A LiFePO4 battery weighs one third that of lead-acid batteries.
- Environmentally-friendly battery: Generally considered free of rare and heavy metals, non-polluting, non-toxic, and in compliance with European RoHS requirements.
- Superior power and thermal/chemical stability
Compared to Lithium ion batteries, lithium manganese oxide batteries, lithium cobalt oxide, and other lithium chemistries like lithium ion polymer batteries (LiPo) and other batteries, including traditional lead acid batteries.
