    Default Lithium 12Ah on a gate motor

    We have just tested a 24V 12Ah imported lithium on a very heavy gate. It worked for 3 days and at least 250 open and close cycles without recharging.
    Very impressed......

    Ah, D10. I thought so. Thanks.
    Edit.
    Sorry, I'm dreaming. Its not a Centurion. But I guess similar to D10.

    I don't know much about the other makes but a few of them use the very same DC motor from the same factory.

    Info on this imported from China battery is scarce. All labels were removed or it came in black propper battery box with bolted terminals.

    I would build one using the loose cells from lithiumbatteriessa a number of guys have built for their solar systems. They have a super cheap 6A for about R65 each. Using 8x3.2V for 12V will be 12Ah.

    I heard that Bluenova have the 7Ah look alike for about R1000 - info from a client.

    I made my own little 12v one from lithiumbatteries.co.za for my swing gate about 8 months ago. Works perfectly. Need to make a 24v one for my garage door.

    What needs to change on the gate or alarm control circuits that would normally charge the lead acid battery?

    It's not just plug and play, or is it?

    Yes, just the standard charger works fine on mine. No need to get fancy.

    We have not done any testing yet. I would guess one will have to look at each PSU circuit. Some give out 13.6-14.2V. As a minumum I would try with a 5A external power supply to increase the charge rate due to LS. Further a diode used at the external power supply to prevent the OE psu to input into the external unit. Volts to battery to be checked as some units will have a diode causing a 0.6Vdrop between the psu and battery. In this case the psu will give an output of about 14.4V. Doing no changes could at times cause the lithium not to charge to 90%+ and lead to a lower capacity.

    Agree, and there it gets really technical, but does it really matter if the damn thing only gets to 90% charge? It has soo much capacity anyway compared to the stupid lead acid, so spending all that money for special chargers and modifications is just not worth it.

    In a proper home UPS installation you would definitely worry about all that, but I just don't see the point for a gate that needs a bit of battery back-up. Mine has been in there for 8 months, no modifications and runs perfect.

    .
    I fully agree with you. That is what I will do but the other side of the coin is you suggest something for the lay man and a gadget sets off the custom smoke bomb and you are blamed
    There could be risk involved.

    I've replaced the 4 x 12v 7ah batts in my 24v APC UPS with 16 x 6ah lithium cells using 2 x BMS's - got it wrong with one BMS being too small, so I got a 2nd one. Sorted.

    Charge voltages, bleh, let the BMS sort that.

    Price was about R1360 for 2 x BMS and 16 cells, close as damn to 4 x 9ah lead acid cells.

    Have a Blue Nova 11ah in my electric fence box and 2 x Blue Nova 8ah batteries in my Eaton 1500VA UPS for a year now, no problems yet.

    Could we use these batteries on our house alarms.
    I find with load shedding I am continually have to replace the standard

    I asked that question too, my alarm supplier said yes, but they need to do something about the existing built in charger, as it is not that cool.

    So just check that IF it is a factor.

    EDIT: Mine now runs off the APC UPS.

    Which BMS's did you use?
    I want to build a battery around 24 to 30 Ah 12V using the small 6 Ah sells, so will need something which could handle a combo of series and paralleled cells. Or do you just series your cells to up your capacity and don't really worry about the BMS not seeing each individual cell? So in effect the BMS only sees 4x 3.2V 24Ah cells rather than 16x cells?

    Got two of these: https://lithiumbatteriessa.co.za/col...4s-12v-lifepo4
    And connected 16 of these cells, 8 per BMS: https://lithiumbatteriessa.co.za/col...e-battery-call

    Connected them 2P4S having made tiny little busbars

    Made my own tiny busbars, like the pic, for between the parallel cells.

    Thanks, maar ek sien hy stock nou 50Ah selle ook, so dalk moet ek net met hulle gan vir bietjie spaar capacity.
