Everything You Need To Know About Lithium Slimline Batteries.

For boaters, switching from traditional AGM batteries to Lithium Slimline Batteries has a lot of advantages. You’ll have less weight and drag on your yacht and increased fuel economy, to mention a few benefits.

It can be up to a third the weight of a lead-acid AGM battery of equal capacity. Anyone who owns a 4WD, boat, or caravan should consider this.

A 100Ah AGM deep cycle battery can weigh up to 38kg, but a lithium battery of the same capacity can weigh as little as 12kg!

That implies you can at least double, if not triple, your vessel’s stored battery capacity or use the lighter battery weight to carry more people or equipment on board.

Lithium Slimline BatteriesEven More Power

Volts x Amps equals power (Watts). As a result, you may get more ability out of a battery if it, 

1) Maintains voltage throughout the cycle 

2) Can discharge more Amps.

In contrast to lead-acid batteries, which quickly lose voltage, lithium batteries maintain their voltage throughout the cycle. It means the lithium battery will produce more power over its lifetime.

Lead-acid deep cycle batteries have a limited load capacity, limiting the appliances they can power.

Baintech’s High Power (HP) lithium batteries provide a continuous output of 200 amps and a peak of 500 amps, making them appropriate for all household appliances, including air conditioning.

Baintech has introduced a new Standard Power (SP) lithium battery series with a BMS that can handle 100A continuous discharge and 200Amps peak.

Increase In Usable Capacity

Lithium batteries have a more significant number of helpful amp hours.

It has a higher useful capacity (amp hours) than lead-acid batteries and does not require recharging.

The discharge depth is expressed as a percentage of its rated capacity, for example, 100Ah.

A lead-acid AGM battery should normally be discharged to only 50% DOD for extended battery life.

A lithium battery can be depleted to 90% of its original capacity. So, a decent ratio to remember is 9/5, or 1.8 times the power of equivalent storage.

You may use the battery for more extended periods without recharging it.

Longer Period of Life

A cycle is defined as the process of charging and discharging a battery. The number of predicted cycles for a given drain depth determines battery life.

At 50 per cent DOD, a lead-acid AGM battery will typically last 500 to 1000 cycles. Anyone who has ever had a deep lead-acid process knows that they only last about 2-3 years before needing to be replaced.

On the other hand, lithium batteries can last up to 5,000 cycles and even longer if properly maintained, giving you several times the life of a conventional lead-acid deep cycle battery.

Lithium iron phosphate cells used by Baintech Marine Batteries have a cycle life of more than 5,000 cycles at 50% DOD and 2,000 cycles at 80% DOD.

This amounts to a life expectancy of +10 years versus 2-3 years for a lead-acid AGM.

Save Time By Charging Quickly

Charge lithium batteries more quickly. It is well known that recharging a lead-acid battery takes time. We all had the experience of charging a lead-acid battery overnight.

Not to mention the amount of charging steps — bulk, absorption, and float – that are required. Lithium batteries don’t need to be set in stages.

Because they have a lower internal resistance, they can accept a higher charge rate. They charge more efficiently, allowing for more energy recovery from solar panels in particular.

Lithium Slimline batteries come in a variety of voltages, including 12V, 24V, and 36V. Reduce the weight and cost of paralleling batteries by using a single battery to meet all of your power needs.
