It was R2100 yesterday.

I see this battery is on special again. Not a bad price.

@wingnut771

Same price. Not 2100

@cavedog, how much you pay?

R2191

R2191

I saw Temu does this spinny wheel thing to get discounts. Did you do those? When I checked your link yesterday I got the same discount as what I got today. I havent bought from there in months and I recall if you are a regular they start giving you more discounts etc.

No I don't do those things. It's all about referrals.

I don't know but once you checkout there is an extra R200 off coupon that gets activated.

Tempting but will maintain discipline.

Thank you. I was R91 off.

You have to checkout to get the discount. It wasn’t an advertised price

but I saw that price from the link he posted without doing anything.

Doesn't your kitchen have enough battery?

Temu was baiting you

I do have enough, but enough is subjective. I hit 7% today. Error 30 and all that. But I was cooking 4 days worth of food last night. I had hit 95% charge yesterday as the clouds had rolled in so I suspect the coulomb counters were not reset. 51.2V with some 50W load should be about 20% SOC, not 10.

You see what I mean by not being accurate, just use voltage mode and print out that voltage chart and stick it somewhere for reference.

What happens if you drop it to 0%?

I dont know, this is the first time I ever went that low with the comms cable connected between the BMS and inverter.

I dont know if the BMS will take care of shutting down or the inverter. I need to check what the SOC cut off is on the inverter. I know the voltage cut off is 48V. Its definitely not 10% as it should have shut down. Maybe the inverter is using the voltage and not the SOC to determine when to switch off.

When it said 7% I should have been somewhere between 10 and 15%.

0% is 40V.

What is bus voltage of 380? You have 3 phase?
