    He also sells new ones for around 30% more. I have 2nd life ones, which is fine I think for running fridges and stuff for camping purposes.

    He sells both new as well as second life cells (in the case of second life it is clearly indicated) - friends as well as myself bought various cells and BMS's from him and I can recommend the kit for the price.

    How old are 2nd life cells, and how long for new ones before they need 2nd life refurbishment?

    Fully agree with this opinion.... I bought four 2nd life cells and a bms a while ago and built a camping battery.

    The cells start life as 150+Ah when new, and when swopped out as part of "planned maintenance", are tested and resold as 120 Ah, second life. But the chemistry should be good for many (thousands) more cycles. I tested by fully charging and then running my nat luna fridge through an Ah meter.... Some 3 days and 127Ah later I switched off. Battery was still at 12.4 volt, probably 10% SOC.

    Since then through many cycles, camping all over. Charging (fast/little losses) with both solar and dc2dc.

    There should be upwards of 2000 cycles in this kit. Very happy !!!!

    Thanks for the feedback, very interesting indeed.

    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 am interested in 154kw Mini HP Tron, can you suggest where to purchase one? Thanks

    Correct on the 150+ Ah in the first live. I have founded that they there is actually 140ah left in them. I got 16 cells of Bain first batch that he imported last year November and a second set of 16 in his 2nd shipment in Feb. Over the lock-down time i had some time on my hands to keep a eye on the BMS and adjusted the settings. I spotted that at 119ah the batteries kept charging on for a bit till the BMS disconnected. So I adjusted the bms AH charging every week. What i founded was that there is about 140ah left in the batteries. I will post later today when i'm back at my house the Ah Cycles on the BMS units to show how many AH cycles my 2 setups did and they still going super strong and i did some hard testing on mine.

    Also these Orion devices are a bit confusing, there are a variety of models and the output voltages seem weird.

    I managed to cancel the CTEK lithium charger before they shipped.

    So where can I get a Victron charger that supports Bluetooth and LIFEPO4 for a reasonable price ? About 5 to 10 Amp, depending on price.

    Also ask Google for prices ... as it can differ a wee bit.

    Hi Guys

    Will be replacing Lead Acid batteries with Blue Nova Life PO4 Battery with Blue Tooth, my setup must support the BN Batteries.

    Setup as follows, could you guys comment, feel free to add or remove :

    * Victron MPPT 30amp Regulator
    * Victron Blue Smart Charger 12/30
    * CTEK D250S Dual Regulator - DC to Dc Charging & has Solar Panel Port(180w Max.)
    * 2 x Rigid Solar 135w 8,5amps Panels

    You need the CTEK D250SE for the LIFEPO4 batteries.

    The rest seems fine.

    Many thanks for the info, have another quick question :
    Will the set up still be ok if 2 more 135w solar panels get added into the mix, so will have 4 x 135w solar panels

    * Victron MPPT 30amp Regulator
    * Victron Blue Smart Charger 12/30
    * CTEK D250SE Dual Regulator - DC to DC Charging with Solar Panel Port(180w Max.)

    Goes beyond saying, and I suppose you have already connected everything, but just be sure that your panels is in parallel. Not serie….

    In a parallel connection, your watts and amps is added up taking you to 540W and 34 Amps , but the volts stays the same. So even 2 panels in parallel is too much for the Ctek

    The D250S will go poof if you say the max it can handle is 180W.

    Serie connecting also wont work as now you add the respective voltages up and the max the D250S can handle is 23V if I remember correctly.

    If the Victron MPPT are to be used exclusively for the solar, then all is good.
