We design and build complete
RV Lithium Battery Systems
Please note we supply our RV Lithium System Batteries
as part of a complete system and do not supply them
for individual sale.
80-90% usable energy compared to Lead Acid which has only 50%
For example, a 100Ah Lead Acid battery will run a
1 Amp light for 50 hours, whilst our
100Ah Lithium battery will run it for 80-90 hours
Hold their voltage very high and stable, coping with large loads easily, so appliances work more efficiently
FOUR TIMES lighter than Lead Acid batteries and a comparable system is much smaller in size.
Charge up to four times faster than Lead Acid batteries
Extremely high life cycle (approx 2000-5000 cycles) compared to Lead Acid which typically has 400-500 cycles, so much greater time periods elapse before needing to replace batteries.
Our Systems can be Customised to suit
No custom system is the same, varying in size and shape to suit, in 12 or
Our Systems are Fully Serviceable
We can diagnose and fully service our RVLSA batteries, ensuring maximum life and reliability.
This is an important advantage.
Fully Sealed LiFePO4 batteries contain all their electronics and battery cells within a sealed box.
It can not be diagnosed or serviced unless returned to the manufacturer who may not even be able to open it.
When sealed batteries are charging and the Battery Control Units (BCU) are operating, heat is created which is trapped inside the battery casing.
This can result in “high temperature cut outs” which shuts the battery off when maximum operating temperatures are reached.
A sealed battery on a hot day or in an engine bay, coupled with heat created from within the battery can result in very lengthy periods without power while the battery waits for the heat to very slowly dissipate due to lack of venting.
Single Battery Control Unit (BCU)
We build our batteries to the required size as one battery, employing a Master Battery Control Unit (BCU) to oversee.
This is a twin BCU with control over Load and control over Charge.
This sets our Systems apart by significantly reducing the risk of catastrophic battery damage caused by the failure of any one BCU in batteries run in parallel.
We test Battery Cell Health & Quality Prior To Installation
Cell health and quality is impossible to test on a sealed battery and is therefore an unknown quantity.
Our RVLSA BCU’s are programmed to cut out at optimum voltage discharge to achieve maximum cycles.
To achieve maximum cycles (each time the battery charges and discharges), and therefore life from a Lithium Battery, our Battery Control Unit (BCU) does not allow the battery to discharge too low, causing damage to the cells.
BCU's in most sealed Lithium batteries cut out at 10 volt which is too low to achieve maximum cycles.
In addition, a Lithium battery discharged to 10 volts should be ‘slow charged’ with a special Charger which means a regular ‘fast Charger’ is damaging the battery cells at this voltage, further reducing the life of the battery.
We are the home of The Lithium Box
The Lithium Box can be moved to anywhere you have an
Anderson Plug connection....your vehicle, solar panel, caravan or camper, whenever you like.
It’s all contained in one neat, compact box.
It’s especially economical for people who plan on changing their Recreational Vehicle, and would otherwise say goodbye to their hard wired Lithium Battery System, only to incur the cost of purchasing another for their latest rig.
The Lithium Box stays with you.
