    Yes I have on the Touareg, but need to do a more thorough long term test still, i.e. a full charge cycle on a battery from empty to full. Charges at around 37 AH. Don't see any issues.

They are easily compatible with most chargers that charge lead acid batteries. What you don't want is something that does a pulse type of charge. Any DC DC converter is perfect. In my practical experience the Lifep04's charge up nicely at exactly the same voltage as lead acid batteries, even off an alternator is fine. If the battery only charges to 99%, it really does not matter. At 13.3 v it's at 90%, 13.4v 99%, 13.6v 100% and 14.4v still 100%.

    I can run my NL 90 fridge on full tilt non-stop flat out for around 48 hours on one 120AH battery. Real-life camping in extreme conditions that would translate to three or four days easy.

    If you run Lifepo4's daily on a system in your house, then you might want to give the charge cycle much more consideration, i.e. no float charge should be applied constantly. For the odd weekend camping, it's really not going to matter.

    Probably the most important thing for camping use is that you should store them at 50% charge, never fully charged or fully discharged.

    I made nice compact portable boxes for mine, - sorry don't have a photo now.

    But best thing I ever did. Would never go back to traditional batteries. The freedom of being able to use them down to 0% without much worry is awesome.

    Thanks for your reply. Something I picked up that I had not heard before is the correct SOC for Storage. I am planing to do a permanent install under the 6th and 7th seats of the disco. So on returning from a trip I should unplug from the DC to DC charger a few hours before I get home and let the Battery discharge until I turn the fridge off. Then I should leave the battery unplugged from the DC to DC charger until I need it again. I see the spec sheet says discharge rate of 3% per month, so I should just watch this aiming to keep it around 50%

    Am I correct.

    I also bought some batteries from LithiumBatteriesSA. Second life Lithiums. I had a 60 kg lead acid 200AH for 2 years and it could not do even close to what the 12kg 100AH lithium can do now. Price wise it is a bargain. What is 2 fancy lead crystal 100AH going to cost which cannot even compare to 1 Lithium

    Thanks
    I'm running mine on a 48v inverter with mppts. I adjusted the inverter to 54.6v bulk and 53.6v for float with 10% amp charge if i need to run from tje grid. The mppts the same volts but running 95% amp charge. It's 2 x 60a mppts.

    The bms I'm using is a Smart Ant bms that got Bluetooth and it's own screen. So i can check all the info of the battery or i can use my phone to log on to the BMS and check all the settings state of the battery. Click image for larger version.

    Cheapest I can find is at https://www.energyon.co.za/shop/blue...ithium-battery

    Less than Takealot and BushPower.

    Wow. I’d assumed that was their “newer” product (hence Bluetooth) - wonder what happened.

    Latest news is that BN will be bringing out a 1.4kWh model with Bluetooth soon. The price and available date is not yet known. The BN13V-108-1.4k without Bluetooth is still available. I think that BN want to standardise their "drop in" range and would then have the 108 available with or without Bluetooth.

    They also have a 13V 154kW Mini HP battery (with Yittrium fortified cathodes) available which is in robust case with a complete BMS included plus local and remote monitoring for firmware updates. Useable capacity 2,000Wh. Weighs in at 25kg and dimensions are 410 x 290 x 300mm (W x D x H) thus it is not suitable as a "drop in" battery. Price is about 50% more that the current 104/108 models thus the cost per kW is slightly higher for the 154HP battery. I attach a spec sheet for information.

    If I was in the market for batteries (I have 2X108's installed in my Companion) that don't have to be drop in's and the space then I would go for a single 154kW Mini HP instead of my current set-up.

    I picked up a BN 104 this morning from Takealot.

    That is disappointing.

    That's an extremely good price for an extremely good LiFePO4!
