Power Grabba Batteries Boxes DC Chargers Inverters Jump Starters Power Packs




Lithium batteries have been around for many years now and have totally changed the way we use many electrical appliances. It’s only recently though, that the advantages of lithium battery technology have begun to be available to motorhomers, caravanners, boaters, campers, four wheel drivers and anyone who relies on 12V batteries for power.

The difference in performance between a lithium battery and a traditional lead-acid battery is so great that anyone who is serious about staying “off-grid” in their Caravan, Motorhome or Camper Trailer really has to consider installing one. It can only be a matter of time before lead-acid batteries for these vehicle types are consigned to the proverbial dustbin of history.

In addition, if you normally use a generator to charge a battery or operate 240V appliances, a LiFePO4 battery means that you probably won’t need this item. This saves money, inconvenience, excess weight and the necessity to carry additional fuel.


Here are ten reasons why you should seriously consider installing a LiFePO4 battery in your Caravan, Motorhome, Camper or 4wd…..

  1. You want to be able to spend as much time as possible “off-grid”.
  2. You want to run a coffee maker, hair dryer, microwave oven, toaster or any other 240V appliance when you’re not on mains hook-up.
  3. You need to use medical apparatus and need to be certain that it will function correctly when needed.
  4. You’d rather use electrical energy than rely on LPG.
  5. You want to save money by not having to pay for mains hook-up ever again.
  6. You don’t want to ever have to worry again about the lights, the TV or other 12V appliances going off because the battery “has died”.
  7. You want to save weight in your set up.
  8. You’ve had enough of lead-acid batteries “leisure” batteries that only last a couple of years or so.
  9. You‘re tired of having to check your batteries, top them up and keep them charged even when they’re not being used.
  10. And finally, because LiFePO4 batteries last so long, they can actually save you money in the long run

20A and 40A DC to DC Battery Charger MPPT Solar LiFeP04 Lithium Compatible 12V Dual Battery System Kit Solar Input.

Designed to manage solar and alternator power inputs to charge an auxiliary (house) battery system. The system will preference solar, providing lower loads on your engine when solar is available. With automatic ignition detection enabled, the system will isolate the starting battery when the engine is off, preventing discharge of your critical starting battery. It’s fully automatic, with a set-and-forget type operation.

The microprocessor controlled circuit keeps your battery in peak condition, automatically switching between six charging modes; Qualification, Recondition, Bulk, Absorption, Check, and Maintenance. Housed in a heavy-duty aluminium case with mounting bracket, and a front panel with charge status LEDs and push button to select between Lead acid, AGM, Calcium, GEL or LiFePO4 batteries.

It handles solar panels with 16 to 25V open circuit voltage, and includes over charge, short circuit, over temperature, reverse polarity, thermal overload, and solar input overload safety protection.
