6 Reasons to Choose a Lithium Battery in your 4WD, Caravan, or Boat!
Moving from traditional AGM batteries to Lithium Deep Cycle Batteries present huge benefits for boaters. Less weight and drag, greater speed in your boat, plus an increase in fuel efficiency to name a few.
REDUCE WEIGHT
It can be up to a third of the weight of the equivalent lead acid AGM battery. This is an important consideration for anybody who owns a 4WD, boat, or Caravan.
A 100Ah AGM deep cycle battery can be up to 38kg in weight, whereas the same size lithium battery can be less than 12kg in weight!
That means you can at least double or even triple the stored battery capacity on your vessel, or alternatively use the reduction in battery weight to bring more passengers, or equipment on board.
Reducing weight helps with Increased fuel efficiency and performance.
MORE POWER
Power (Watts) is equal to Volts x Amps. Therefore, you can get more power from a battery if it 1) holds its voltage over the cycle, and 2) is able to discharge more Amps.
Lithium batteries hold their voltage over the cycle, unlike lead acid where the voltage drops off almost immediately. This means more power from the lithium battery over its cycle.
Lead acid deep cycle batteries are limited in the amps they can discharge which limits the appliances they can run.
Baintech High Power (HP) range of lithium batteries are capable of 200A continuous output and can peak at 500A which is suitable for all household appliances, even air con.
Baintech introduces a new Standard Power (SP) range of lithium batteries in which the BMS can accommodate 100A continuous discharge and can peak at 200Amps.
GREATER USABLE CAPACITY
Lithium batteries have more usable amp hours available.
It provides more usable capacity (amp hours) than lead acid batteries before needing to be recharged.
Depth of Discharge (DoD) refers to the discharge depth of a battery as a percentage of its rated capacity, e.g. 100Ah.
For a decent battery life, a lead acid AGM battery should typically be discharged to only 50% DoD.
A lithium battery can be discharged to 90% DoD. So, a good ratio to remember is 9/5 or 1.8 times the comparable storage capacity.
You can use the battery longer before needing to recharge without damage to the battery.
LONGER LIFESPAN
Every time a battery is charged and discharged is called a cycle. Battery life is rated as the number of expected cycles at a particular depth of discharge.
Typically, a lead acid AGM battery will last for around 500 to 1000 cycles at 50% DoD. Anyone who has ever had a lead acid deep cycle knows it only generally lasts for 2-3 years before requiring a new one.
Lithium batteries on the other hand are rated up to 5,000 cycles and much more if used carefully, giving you several times the life expectancy of standard lead acid deep cycle battery.
Baintech Marine Batteries use lithium iron phosphate cells that last more than 5,000 cycles at 50% DoD and 2,000 cycles at 80% DoD.
This equates to +10 years of life expectancy compared to 2-3 years of a lead acid AGM.
SAVE TIME, CHARGE FASTER
Charge lithium batteries faster.
Everyone knows that to re-charge a lead acid battery takes time. We have all experienced putting a lead acid battery on charge over night!
Not to mention the number of charging stages required – bulk, absorb and float. Lithium batteries don’t require complex multistage charging.
They have less internal resistance and so can accept a greater charge rate. They charge more efficiently, meaning more energy can be recovered from solar panels especially.
As a result, they charge faster than lead acid.
Example: A 25A AC charger will charge a 100Ah lithium battery faster than a 100Ah lead acid AGM!
SAVE MONEY
When comparing, consider total life-cycle cost. Consider the overall cost of ownership.
People who are put-off by the upfront cost of lithium batteries do not consider the total life-cycle cost.
When considering the usable capacity and lifespan, they work out cheaper than lead acid in the long term.
You might go through 3 or 4 lead acid batteries in the same time as a single lithium battery.
When you add the cost and inconvenience of refitting new batteries every few years the total cost of ownership over the long term is far better with lithium batteries.
