    31st March : ML V=12.70   Y=330Wh Removed a solar panel mid afternoon, so only one 250w input.

    30th March : ML V=12.64Y=310Wh
    29th March : ML V=12.59Y=410Wh
    28th March : ML V=12.65Y=510Wh High yield as used electric plane.
    27th March : ML V=12.60Y=160Wh Low yield as power not used during day.
    26th March : ML V=12.60Y=???Wh
    25th March : ML V=12.70Y=220Wh
    24th March : ML V=12.74Y=340Wh Used angle grinder so yield is higher.
    23rd March : ML V=12.84Y=240Wh
    22nd March :ML V=12.68Y=560Wh Used angle grinder so yield is higher.
    21st March : ML V=12.82Y=210Wh
    20th March : ML V=12.63Y=300Wh
    Reset VD as it had started new day before mdnight, this brought the ML upto 12.63 ~could have been higher?

    19th March : ML V=12.40Y=290Wh
    Strange that the ML is low @ 12.4 and there was 20watts usage overnight

    18th March : ML V=12.75Y=160Wh
    Must check electrolyte again.
    Notable is that the ML is high yet the yeils is only 30w or so about the useage

    17th March : ML V=12.40Y=180Wh
    Left router on all night :(

    16th March : ML V=12.60Y=160Wh
    Although to ML voltage was 12.6 the record shows it was 12.32 when switched off last night and now I have loaded with comp, router and led it is 12.24.
    Yield of only 160w but battery was on abs for 2h and float for 8hr
    May adjust the abs time span

    15th March : ML V=12.70Y=240Wh

    Though the last two days yield has been below 320w the 41Ah battery is fully charged with some 145w usage. Maybe smaller batteries is the key.

    14th March : ML V=12.72Y=220Wh
    ML V =12.72 Check elecrtolyte levels.
    All cell were covered but added aprox 32ml of rain water to each.

    13th March : ML V=12.55Y=290Wh
    12th March : ML V=12.64Y=360Wh
    11th March : ML V=12.56Y=420Wh
    10th March : ML V=9.99Y=160Wh
    13:20 Changed Battery ~ removed last of Rolls 125AH and temp using a 41AH car battery that Gavin lent me.

    9th March ::: ML V=10.03Y=380Wh

    In general all our products are designed in The Netherlands and manufactured in Asian countries due to cost price reasons.

    You can ask such questions to your supplier, they see the country of origin on the invoice they receive from us.

    The SuperPack is made in China , mainly Chinese technology, only to be used in small 12V systems.

    The normal Lithium batteries LiFePO4 we offer in 12 and 24 Volt are also manufactured in China, the cells are Chinese lithium cells, we design the balancing system in the battery and the external Ve-Bus BMS you need to use them with our products.

    Keep in mind that most of the Lithium cells used in the world come from China, they are the best it looks.

    Country of Origin can be manipulated a bit by buying the cells from China and completing the product in another country.

    Our 12 and 24v Lithium LiFePO4 can only be used for 12 or 24v applications, for 48v Lithium to be used with our products we recommend third party Lithium batteries like BYD and other brands mentioned on our website.

    With best regards,

    Jan Klumpenaar, Sales Manager

    It appears as if all the batteries have a cell shorted as they drop to 10.8 as soon as the charging stops. Very starnge3 thtr they all shorted at the same time.
    However this means I am charging at too high a rate now and have dropped the charge voltage by 2v.
    Will try and repair the batteries.

    From 5th Feb the charging voltage is 13.92 so the solar input will be low. The available power could have been more than 1Kw

  • 1. Makita Hammer drill 2 speed, variable, reversible, 750W
    2. Seem to have lost the Black and Decker Found : Oct 2019 Was at Rowena's for the last few years. Though I have it working the speed control is duff and the chuck is on it'd way out,

    3, 25th Jan 2020
    Tuai gave me his old portable drill set, though the screw-driver chuck has a broken piece in it that requires removing before it can be used.

    DHP 481 and

    Charged the two batteries, Had a bit of a time working out the LED light indicators,
    DC 18RC Makita charger

    1. Plug the battery charger into the proper AC voltage source. Charging light will flash in green color repeatedly.
    2. Insert the battery cartridge into charger until it stops adjusting to the guide of charger. Terminal cover of charger can be is opened with by inserting and closed with pulling out the battery cartridge.
    3. When the battery cartridge is inserted, the red charging light will light up and charging will begin with a preset briefmelody sound coming out for assurance as to which sound will come out to notify the completion of charging.
    4. With finish of charge, the charging light will change from red one to green one and the melody sound or buzzersound (a long beep) comes out to notify completion of charge.
    5. If you leave the battery cartridge in the charger after the charging cycle is complete, the charger will switch into its“trickle charge (maintenance charge)” mode which will last approximately 24 hours.
    6. Charging time varies by temperature (10°C (50°F) – 40°C (104°F)) that battery cartridge is charged at andconditions of the battery cartridge, such as a battery cartridge which is new or has not been used for a long periodof time. 7. After charging, remove the battery cartridge from the charger and unplug the charger from the power source

  • Have emptied the electrolyte and fished the cells with a hose, filtered the electrolyte and replaced it.

    The battery was at 6.54V and have now connected it to a single 250w pv panel and am monitoring the voltage. There is no controller so the max current will be around 8A
