Is that a good deal? Why not just get omnivolt from builders already build for R26k for example

How long is the warranty?

You can fix a diy battery yourself like replace bms or cell and set your own settings in bms with bluetooth. 16kWh for ~R28k. Guaranteed to have a long life.

Budget prebuilt systems are lucky packets imho as they have short warranties and if something breaks in a few years then you are stuffed.

Yeah but for DIY projects like what I want to do on a 12v pack it's not worth it. Maybe if I'm repairing my ecco battery packs if they fail.

Boy-That-Escalated-Quickly-Anchorman.gifWhat 12V pack? No doubt the builders deal is still good price for 15kWh.

Ag I don't know I'm like lifepo4 befok now. I just want to diy and play around with it a bit and see how things work etc so a 12v 100ah diy battery pack seems like a good start. No so expensive and only 4 cells so less risk if I do it outside.

Do you have a 12V PSW inverter? What will you use this for?

Why would you want to do this when you have 48V already?

Yes I have a small 600w PSW inverter. That is what I was using the 2 solar panels and the victron mppt on. Just checking stuff out.

Probably better (cheaper) to buy preassembled 12V 100Ah then as it already has a case making it sort of portable:

That is a decent price. Those 300ah temu batteries really went up.

So for R50 cheaper I can build the same battery with temu parts and secondhand cells. Damn diy builds aren't really affordable compared to all these packs.

I believe the subsidies are being removed for renewables in China. BYD also losing its gvt subsidy. So prices for solar stuff might start going up. Especially batteries.

Arent those subsidies for EV's?

Anyway, all batteries are made in China anyway so whats up with the local cheapies being cheaper than temu?

Might have misunderstood it. But BYD and others are some of the largest battery guys so no subsidies should theoretically mean higher prices?

I only see one battery on Temu. 3.5k. Is that considered expensive compared to local? They used to have more variety but now it’s only one.

But note that the same manufacturers (SJY) are selling on Takealot. I suspect they just selling directly local rather than through Temu.

Like this one. Was only on Temu. Now it’s not on Temu but sold locally. People that would buy these would say the battery never looked like the picture even though the capacity was as stated.

Suspect local are just buying in bulk and get cheaper rate and resell with different branding.

Thats why you always see chinese EVs being advertised for so cheap in china, because of subsidies.

Don’t tempt us here🤣. With my current setup running things at night and only charging during the day seems to be working well. Have gone as far as connecting all the plugs of the TV, pool etc to the 5kW.

Only bedrooms and lights are on 3.6 now. A second battery would have me running the pool at night coz why not🤣.

Made some food in the oven.

GEL batteries are cruising sitting at almost full in the morning most days now.
