Hello House,
Be like I don be victim of lead acid not the best oooo.
Is it possible to wake/charge dead lead acid battery? cry cry cry cry cry cry cry
My ba3 drained completely, so I took it to where I can charge it but was told it won't charge as the thing no get even small charge.

My small souer 10a charger has woken car battery from 0v more than once.

I pulled 209AH on that day but had to turned off the inverter manually that day. You can see it from my customized emoncms picture attached (Day Deepest Discharged). The data is from my BMV 702.


I see it's the 24v 250 model and they've written that it's 5kwh usable.....so that means you pulled 5kwh as d.... assuming your BMV meter is accurate I will say that's unlike Felicity but that's good of them!

The place I went to charge it told me that na car ba3 person fit wake from 0v.
Well I was able to get charger/booster last nyt and attached is the picture of the charging/boosting.

What type of lead acid agm, gel or flooded do you have.
emyfine08: 10:41am On May 21, 2022
what type of inverter are you using?
hope you configured it properly to charge lifepo4 battery?

felicity uses different battery types in their packs, some good, most fair..and a few downright not good.
so yours might be among the few good ones, if everyother thing check d out ok. hv seen felicity pack with cheap used byd cell packs inside[/quote]

I don't use inverter to charge it is only Soler 350w by 12 we don't have nepa

@bolded is quite untrue.

The MC4s are designed to ensure perfect and fit with themselves. They are weatherproof and designed to last the lifetime of the . They are also rated to handle the current that flows from the s. That is why arcing is quite uncommon at their points of s when used in installation, whereas the naked wires (after the MC4s are decapitated) will form arcs when huge current es across the twist junction. This gradually weakens the t and eventually the t burns out, disrupting flow from the s down to the CC, hence your voltmeter may give correct voltage reading at the termination on the CC, but no current will be detected by the CC. The naked wires too (even with black tape insulation used), are prone to oxidation as they get exposed to the elements.

So if the problem of arcing does not occur soon, oxidation will definitely come along later. The wire develops depositions, the strands become brittle and break off easily. You don't want to have this kind of problem if your s are roof mounted where they are not within easy reach.



I guessed as much.

If your s are roof mounted, sorry you will have to climb back on the roof. If it is a weak t, twist the wires well. If it is an arc t (with dark burnt junction and melted insulation), then you have to cut off the bad section and make another twist. After the correction, check back on the CC to see if its charging.

But I can assure you that the problem will likely repeat itself later on as it has to do with the junction not being optimal for the current coming from the .

So your best bet, which I implore you to do, is to purchase MC4s and rẹ-fit back to the wires.

Thanks so much
I just got a meter, the cable reads 33v when removed from the cc, but reads 12.5v after inserting into the cc, I have climbed the roof top check the t, theres no acrk or so but I haave retwisted and still the cc dint display the real volt I got from the pv
gadgetplanetng: 1:10pm On May 22, 2022
PWM charge controllers behave the way you just described when you connect a 24v to a 12v battery.

They drag the voltage down to battery voltage so you end up using half the capacity.
An mppt would use the voltage and adjust current accordingly.

But it should still charge

1. You should be able to adjust the charge settings in the cc
2. You can get an MPPT cc
3. You can get 12v (18v) s

I'd have added upgrading your battery bank to 24v but I've not had a good experience with pwm and 24v.

Okay, I didn't get voltmeter to test it immediately. Hoping to get one soon.
Though based on booster reading should be around 11.5

The ba3 has come up, na light I dey wait for to further boost the ba3.
Thanks.

Well great charge it very well, with utility , we are in rainy season. It should pick , so far it is not a gel battery,
