Solar Energy Storage

Due to low prices, subsidies by the government, and improved solar technology, people worldwide are investing heavily in solar battery kits that are meant for overcoming climate change threats, power blackouts, and independence from expensive grid electricity. The role of solar power storage batteries is crucial as the sun isn’t shining all the time. These batteries are essential to compete with electricity produced by fossil fuels. From 2000 to 2018, the total installed solar capacity grew from 1.25 GW to 485 GW. China is the global leader in producing more solar energy with 254 GW functional capacity by 2020. Australia also made headlines regarding the highest solar per-capita capacity with 637 watts per individual. At the same time, the country will start exporting solar energy to Singapore via the world’s largest solar storage battery.

The battery world was revolutionized by adding a Lithium-ion battery known for high-end features that no other battery type offers. The key features include low self-discharge, high energy density, lightweight, no maintenance like flooded acid battery, and thousands of life cycles.

48 volt lithium ion battery charger48 Volt Lithium Ion Battery Charger For Fast Charging Your Lithium Battery

With the advancement in battery technology, Lithium-ion batteries are on the rise. Lithium batteries have widely been adopted, ranging from cell phones laptops to gadgets and usage in other large appliances such as inverters and home backup systems. Lithium batteries have safe chemistry with their cells immune to discharging and cell damage due to improper half charging cycle. Lithium battery requires a specialized 48 volt lithium ion battery charger to charge 48v lithium battery efficiently.

Lithium charger supports fast charging of the batteries while maintaining their long-lasting life. Lithium battery charger provides Constant Current (CC), followed by Constant Voltage (CV). This limits the voltage to carry out safe charging of these batteries. In normal circumstances, a lithium charger fully charges the lithium-ion battery when it reaches 13.3V-13.4V. In comparison, the lead-acid battery only requires 12.6-12.8V. Lithium chargers are necessary to ensure the best battery life and charging. Deep Cycle Systems produces the best quality lithium chargers.

Deep Cycle System manufactures the best quality Lithium battery charger for our valuable customers.

Why is a Lithium-Ion Battery Charger Useful?

A typical battery charger used for charging a lead-acid battery can charge your lithium-ion battery. However, a standard lead-acid battery uses low voltage for charging. Henceforth, a lithium-ion battery will only be charged 80% by a standard battery charger. In addition, a specialized charger for lithium-ion batteries charges at least five times faster than your typical battery charger.

Advantages of Lithium-Ion Battery Charger

A lithium charger provides a constant voltage to the battery when charging and peak performance. In return, the lithium-ion battery delivers peak performance irrelevant of the load. Henceforth a good lithium charger will enhance your practicality using the lithium-ion battery.

A lithium-ion battery inhibits discharge when not in use. Hence if only loses 5% of the charge in a month of not in use. On the other hand, a typical lead-acid battery loses at least 20% of the order in a month when not in use. Henceforth, the low discharging ability of lithium-ion batteries makes them more durable than a lead-acid batteries.

48v lithium ion battery chargerHow Can You Select The Best Lithium-Ion Battery Charger?

48v lithium ion battery charger works perfectly for charging your lithium-ion battery. A correct charger for your battery provides the right amount of voltage to the battery, enhancing battery life.

Lithium-ion battery charger needs to be compatible with the battery. The exact voltage required to charge the battery is necessary. It is because the lithium batteries should not be overcharged as they are sensitive to over-voltage charging.

AMP–Hour rating should always be checked when deciding on a lithium-ion battery charger. An insufficient amp-hour rating will only cause damage to your battery; hence you need to select the correct amp-hour charger.

Lithium Ferrophosphate (LFP) is a flame retardant, stable, safe and proven cell chemistry that has a very good energy density around 325 Wh/L. This cell chemistry can be engineered for various applications by adjusting the ratio of elements to provide high performance characteristics. E.g. the DCS marine battery range runs 2C cells, which means our little 75Ah battery will discharge comfortably at 75Ah x 2C = 150A. The DCS 80Ah Extreme runs 10C cells which means the 80A can comfortably discharge at 80Ah x 10C = 800A but is of course limited to lower currents due the the Battery Management System.

LFP also has very good cycling durability between 2,000 ~ 12,000 cycles can be achieved depending on how well the cells are managed, and the lowest rate of capacity loss (aka greater calendar-life) compared to other lithium cell chemistries.


Battery cells are simply a bunch of resistors with the ability to store energy. A 100Ah battery pack has a different resistance characteristic compared to a 50Ah battery pack, that theoretical difference in resistance is 2:1. So if you connect a 100Ah battery in parallel to a 50Ah battery there is no way for these two batteries to equalise and therefore you can’t charge them correctly. So for example connecting a 60Ah calcium starting battery to a 120Ah AGM via a VSR (Voltage Sensing Relay) you cannot charge both batteries correctly and from that day onwards you are prematurely destroying both battery packs. Same theory applies with lithium’s it’s still a battery pack.

What’s the solution? A DC-DC charger, you now have a permanent point of isolation (meaning that both batteries are never connected to each other in parallel). The DC-DC charger takes the surplus power from battery A (engine) and chargers battery B (aux/house). This device now allows any battery capacity and or chemistry to be used.

What if both batteries are the same, can I run a VSR between exactly the same two batteries?

Yes you can, but lithium’s have a different voltage curve, so you would still need to use a programmable VSR to dial them in correctly. However these devices draw a lot of power when engaged to so it’s best to run the two batteries in parallel and run a load disconnect instead of a VSR.

The advantages of the lithium battery cell chemistry

Lithium battery cells have a super low resistance so are very easy to charge and very efficient. This level of efficiency means you can charge them at very high C rates. For example if you look at the charge rate of a 100Ah AGM battery the recommended charging current will be around 25A, which is a 0.25C charge rate. If you consider the DCS 12V 100Ah Lithium battery it can be charged at up to 70A which is a 0.70C charge rate. This means you no longer need to consider DC-DC chargers as you can connect our batteries directly to high power charging devices such as suitable alternators, or large buck boosters. For example our popular dual 90Ah battery system for boats and 4WD vehicles, can be connected to alternators up to 160A.


Because our batteries are internally voltage regulated and because our BMS has such a high sustainable peak discharge current they will do an amazing job of equalising very quickly.


The BMS will open circuit the battery terminals to protect the cells. This means there is no longer any resistance in the system. The BMS needs a 12V signal with at least 1A of current to release and wakeup from a cell protection state. Most mains chargers with a lithium profile will do a slow recovery charge as will most solar regulators. Some chargers in the market today that are advertised as ‘lithium’ compatible still don’t have the firmware to do a slow recovery charge to release BMS’s. If you have a charger that will not wakeup the BMS, easiest way to wake it up is to connect a unregulated solar panel directly to the battery terminals, ensure all loads are disconnected before you do this. Having said that every system should have a suitable low cut off voltage to shutdown loads/accessories so that the batteries are not fully drained.


Use the following settings:

Charged voltage 14.0V
Tail current 4%
Charged detection time 1min
Peukert 1.05
Charge efficiency 98%
Current threshold 0.1A
C rates: refer to the battery pack capacity

What is the best state/charge to store these batteries ?

Fully charge to 100% isolate everything from the terminals and leave for max 3 months and then cycle (fully discharge and fully charge) and leave again for 3 months etc…. Minimum 4 cycles per year to not effect the cells capacity.
