Did you know that Lead-Acid was the first type of rechargeable battery, invented in 1859? Even though many improvements have been made since, the technology just doesn’t live up to the modern needs set primarily by mobile phones and tablets. In lack of a modern type of energy storage for a yacht or RV, users have to live with Lead-Acid and its shortcomings. Lithium batteries are available for Yachts and RV’s but installation often requires a rebuild. Also the State of Charge has been hard to measure due to the flat voltage discharge.
SUNBEAMsystem SMART L I T H I U M was developed from scratch to solve ALL problems found on other batteries available today. It is highly efficient, fail proof, easy to install and user friendly.
Plug & Play
SUNBEAMsystem SMART L I T H I U M is a drop-in replacement for your low-tech domestic batteries.
As opposed to other Lithium battery solutions the SUNBEAMsystem SMART L I T H I U M battery is fully compatible with old Lead-Acid batteries, without the need for additional relays or rebuilding the existing system. One can even keep Lead-Acid batteries in the circuit if needed. Several SMART L I T H I U M batteries can be installed in parallel. There is no need to change or alter the generator nor the shore power charger.
We call this Plug & Play!
When installed the batteries can be easily monitored via our Bluetooth APP, available for iOS and Android.
SMART L I T H I U M Smartphone APP ger en utökad kontroll på laddningsstatus och omgivningsdata. All information är lättillgänglig för dig som användare. Information om batteriernas hälsa är även en fördel för andrahandsvärdet.
By choosing a LiFePO4 chemistry, we reach a level of security higher than any other chemistry available. LiFePO4 is superior to any lithium type battery used in mobile phones or computers in regard to safety. On top of this high security we add another layer of security by implementing a safety vent on each battery cell.
Together, this makes it possible for us to certify the battery under the UN 38.3 legislation, guaranteeing it’s safe for air-transport. This means the battery is safe even after penetrating or crushing cells. It also means we can guarantee safety in extreme external conditions such as fire, changing air pressure or repeated vibrations. The product is tested on shock impact, short circuiting and overcharging.
On top of this we also offer the built-in safety provided by the smart and fully automatic battery management system.
All-in-all the multi layered security makes it the premier safety choice for sensitive vessels.
The lifetime of a SMART L I T H I U M is incredible. Even after 2000 cycles of fully empty and fully recharge (0.5C) everytime, It will still remain at least 80% of its out-of-factory storage capacity.
In real life, not many users will cycle full to empty hence many producers refer to a 50% discharge level. at which we will get an astounding 5000 cycles. Especially compared to Lithium-ion batteries, often found in smartphones, who will only endure 400-1200 cycles.
|Urladdningsdjup||80% av ursprunglig kapacitet kvarstår efter|
|100% – 0%||2000 cykler|
|100% – 20%||2500 cykler|
|100% – 30%||3000 cykler|
|100% – 50%||5000 cykler|
Hence SMART L I T H I U M will not only offer peace of mind – it will be a lot cheaper to use compared to a Lead-based battery.
The round trip energy efficiency of a LiFePO4 battery is 92%, compared to a Lead Acid battery with about 80% efficiency. These values are calculated at low currents, when faced with higher currents this gap will become even larger.
SMART L I T H I U M will allow for higher currents, both while charging and discharging, without the increased energy loss experienced in a Lead Acid battery. The most noticeable result is that the charging rate from the engine alternator/generator will improve. Even without an upgrade or rearrangement of the electrical system all users will experience shorter charging times. With the right equipment the SMART L I T H I U M could be Quick Charged in under one hour.
Almost all energy stored can be used, minimizing the need to run larger consumers like a fridge only during charge.
The voltage will stay at approximately 13.3 Volt through the main part of the discharge cycle. Even under high load the voltage will be almost untouched compared to a lead based battery. This is thanks to the high efficiency in the battery but will also lead to a more effective use for most appliances in the electrical system.
Batteriet är uppbyggt av runda celler enligt samma princip som Tesla använder i sina fordon. Det minskar värmepåverkan vid höga strömmar. Batteriet kan snabbladdas på mindre än en timme. Farten begränsas dock I de flesta fall av externa faktorer såsom utrustning för laddning.
All capacity (100Ah) is fully available on a Lithium battery, while on a lead-based battery a discharge below 50% will permanently damage the battery.
In addition, virtually only solar panels or a grid connected power charger are able to (slowly) charge a Lead based battery above an 80% charge.
The above two serious flaws are the reason why it is common to explain the difference between Lithium and Lead batteries as if 100Ah Lithium corresponds to a 200Ah Lead based battery. In other words, the usable stored capacity is twice as high. This on a battery half the size and weight of a lead battery.
The constant loss of power over time, found in conventional batteries, is history. Going away for a longer period (> 1 month)? Simply disconnect the battery from the charger and enjoy a ready-to-use battery on return.
|Capacity||Max cont. charge||Max cont. discharge||Pulse discharge (10s)||Weight||Dimensions (mm)|
|100Ah / 1300Wh||150A / 2100W||150A / 2000W||450A / 6000W||14,5 kg||340 x 170 x 210|
