(SolarKing) 200AH Compact Lithium Battery

The SolarKing 200AH lithium battery is ideal for heavy load applications or in situations where you are based in the one camp site for an extended period of time and can’t always rely on solar recharging.  The battery packs offer a tremendous amount of power storage and will easily run all of your typical 12V equipment including larger 2 way fridges, CPAP machines, LED Televisions, LED lighting, larger inverters and more.  Parallel connect 2 of these together for a whopping 400AH.  And just like the rest of the lithium range of batteries, the 200AH features internal heavy duty management system with electronic cell monitoring.

SO HOW MUCH BATTERY STORAGE SHOULD YOU HAVE? 

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.

WHAT IS A BATTERY MANAGEMENT SYSTEM (BMS?) 

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? Big weight savings to be had by changing over to lithium.  Only 23.7KG for the 200AH Compact.

3 YEAR WARRANTY 

The  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.
