    The article does not mention that if you install a LiFePO4 (Lithium) battery that for safety you must use a different type of fuse in the positive cable that connects to the battery. LiFePO4 batteries are capable of producing very large currents in short circuit situations, so large in fact that for most fuse types the current can arc across the fuse holder, even when the fuse has blown. For absolute safety you should use a Class T fuse. At a minimum a Marine Rated Battery Fuse (MRBF) should be used. Some will argue that the battery management system (BMS) will protect the electrical system in the event of a short circuit. However, it is possible for the BMS to fail and current continue to flow. Therefore, it is important to ensure that the correct type of fuse and fuse holder is used for connecting the battery to the 12V electrical system.

    I would like a reply to John Cork’s comment above Please!

    Please explain ??200 duty cycle for a lead acid battery vs 4000 for a lithium battery. 4000 devided by 200 thats 20 times more duty cycles, not 200 as stated.

    Lead Acid batteries can only be discharged to about 50% before they start to suffer permanent damage, lithium can drop virtually to empty without damage. Charge times for LA batteries are also much longer than for lithium. Equivalent outputs would weigh twice as much with LA batteries.
    Having said all that, I’m still using 2 x 100ah lead Acid batteries with two 120 watt solar panels and a 2kw inverter and seldom run into any problems but if it’s not a bright day after 6 brews using a 1200w kettle for 2 mugs of tea I have to revert to using the gas hob!

  5. John Cork says:

    A correctly-sized charging system involving solar panels, charge controller, lead-acid batteries, and an inverter would provide almost identical performance to what has been described here in this article, at a fraction of the cost of using lithium as the choice of battery.

    The article, in my opinion, is simply an advertisement for lithium batteries, and should have been clearly stated as such in your publication.

    • We’re sorry you feel this is an advertisement for lithium batteries John, as that was certainly not the intention. It was aimed to explain more about the use of lithium batteries in a motorhome.
