SolarKing lithium batteries are the ultimate solution for power storage and usage in the caravan, RV and marine applications. Completely sealed with zero maintenance, our  100AH lithium batteries are much lighter than lead-acid and AGM batteries (only 11 KG as opposed to 30KG for lead-acid) and their cycle life is more than 4 times that of lead-acid batteries. Up to 8000 cycles is possible if the battery is well looked after and even under heavy loads every day (drained to 25% capacity), can still achieve minimum 2000 cycles making them more economical than a lead-acid battery when calculated over time.


Well, this depends on your power requirements.  In most cases where you are powering LED lights, a TV and recharging laptops and low power devices and your fridge is a 3-way unit able to run on gas, a single 100AH lithium battery will suffice.  With 300 watts or so of solar on your roof, you’ll be able to top up your batteries daily and even with several cloudy days when there is little solar charge coming back in, you’ll still have ample battery storage available.  For those of you who spend a fair amount of time away and running heavier load items such as a 2-way 12V fridge, inverter, lighting, TV etc, we would suggest a single 150AH or 200AH lithium battery or 2 x single 100AH lithium batteries connected in parallel.  This is a huge amount of storage that will get you through those cloudy days until the sun comes back out and recharges your batteries via your solar panels.  


All SolarKing lithium batteries feature heavy-duty BMS circuitry inside the battery casing.  The BMS looks after the battery by monitoring the incoming charge voltage and the discharge voltage as well as temperature cut off in the unlikely event that the pack runs too hot.  The BMS will also protect your Solarking battery by switching off the voltage output if the capacity reduces to 20% or less.  This prevents cell damage and can be reset and charged back up to an acceptable state of charge.  There is much debate about whether a standard lead-acid charger can be used with drop-in lithium LiFePo4 batteries with a built-in BMS.  From our research, we suggest that any charger can be used providing it has a custom profile.  Within the custom profile, charge rates should be set to 14.6V bulk/absorb charge and float turned off or set to 13.3V (equalisation must be set to zero or off).  The benefit however of having a lithium specific charger is that the battery will be returned to a full state of charge faster and more efficiently.  How about weight?   Well, this is the real winner.  Less than half the weight of a lead-acid battery is so typically about 30KG for a 100AH lead-acid and only 12.KG for our  lithium LiFePo4 battery.  Less weight, better fuel economy. 


The SolarKing range of lithium LiFePo4 batteries is covered by an Australian 3-year warranty against defects and failure.  This is a return to base warranty and if found to be faulty, will be repaired or replaced during this period.
