    I havent looked too closely - but how seems only Flexopower can swap that battery for you when it dies. not necessarily a problem - but in 5 years time - that thing might be obsolete and you have to buy another product again. Can't win I do find my 444 very useful.

    Does the Lithium555 have a screen like the Jackery so you can monitor charging etc instead of just lights on the 444?

    Flexopower looks like the best option so far.
    I did exactly that but went a bit overboard.
    Modified the green box from NL and mounted it out of the way.
    Works like a charm.

    Looks good!

    I see Solar input 5A max - is this normal for lithium?

    (Solar Vmp 18V - 24V, 5A max.)

    Paul - you need to check each product as they all differ. The Delta 1300 takes 10A for instance

    Yes. Big gripe. This is the issue with charing while you drive - you hardly replace what your fridge takes out, which means this is not a viable option for me at 5 A

    A lot has been said about charging in a car - mostly no one is impressed.
    Charging off solar is pretty good though. (in my opinion)

    tough decision between choosing the ecoflow and flexopower. The one in and outflow more with smaller battery vs opposite on the other.

    Do we know if the handles can be removed to fit it in even tighter spots or put items on top of it?
    And if you charge through the 12V socket of the car, while fridge is plugged in in the unit and not in the car, will it even gain charge?

    Very keen to get one of these.

    I have to stress that I am no expert on any of these products. I do own a 444, but do not use if for my fridge.
    I have been looking around myself for a little while - so I am also in for info-gathering fase.

    In my case charging the 444 while driving problem was related to the smart alternator issue however, when I installed my Victron Dc to DC for my 120ah Lithium the smart alternator override solved this problem and it charged quite easily. In my son's Triton there were no issues as it has a normal alternator my assumption is that we were actually charging at about 7.5 amps if I relate usage to charge time.

    As for Solar I recall that the specifications actually stated that you can match it to a 120watt solar panel which will at 16v also gives about 7.5amps.

    A year + ago Flexopower sold a 444 paired with a 150W fold up panel as a bundle> Checked the discrepancy with them (120W vs 150W) and they advised at the time that it is perfectly fine -

    If you look at the 444 specs - INPUT Cigarette Lighter 12V / 6A

    I would imagine that is not to be confused with charging via a DC/DC system?

    Keep in mind this battery pack already costs 3 arms and 2 and a half legs - if you have to set up your whole DC/DC system too - ............ (unless you have it of course - I am thinking more along the lines of a fresh set up)

    In my case the Dc to Dc was charging a separate system but the spinoff was that it allowed the alternator to provide more than enough power to cigarette lighter to charge the 444 as well as the 120ah lifepo4.

    This is a good exercise to do, just to get all the apples to look like apples. It so happens I have just completed a portable diy battery box based on Victron and Blue Nova lithium components. These are its parts:

    1. Blue Nova LiFePO4 1400Wh (108 Ah when consumed at 12v within 10 hours).
    2. Victron IP65 Bluesmart 15 amp ac to dc charger.
    3. Victron Orion-Tr Smart 12 | 12 30 amp dc to dc charger.
    4. Victron SmartSolar 100v 15 amp pv to dc charger.
    5. Victron Phoenix 12 | 500 pure sine dc to ac inverter.
    6. Victron BMV-712 Smart shunt to read it all.
    7. 35, 16, 6 and 3 mm2 cable in varying lengths, copper busbars, lugs, heat wrap, fuses, Victron 275 amp switch, Bager fusebox, NL sockets, nuts, bolts and washers galore.
    8. Crimping, cutting, drilling, torquing and screwing tools.
    9. Specialized woodworking tools.
    10. Lots of labor, caffeine and alcohol.

    The resulting box measures 540mm long by 270mm wide by 300mm high and weighs a whopping 28 kg, excluding chargers and inverter (the battery weighs 14kg: marine ply is heavy!).

    This all cost R32,000.00 or R 22.90 per Wh.

    These attractive, small-footprint, reasonably priced boxes start looking like the answer, I'd say.

    Thing is this: the beauty boxes have the following shortcoming: no DC to DC charger. Charging via 12V sig lighter at 5 or 6 Amps, is in my humble opinion, not good enough.

    Secondly - if the battery dies in a beauty box, most of them I assume you just throw away? No good either.

    Just keep in mind, that 444 unit is a 37AH battery. 6A charge rate is already way over a 10% charge rate, which is a good safe rate for a steady charge current.

    The Solar charge rate would also be internally regulated to a safe limit, independent (somewhat) of the size of the Solar Panel, up to some limit. A larger panel gives better performance in low light but will still be limited to a safe max.

    Hi Roelof, you could fit 2 x Li555 in a low lid ammo box and have space left for accessories.
