i have not used it, but dont waste money on that bro.

efuro:

Not using 2v batteries oo. I run my setup on 20 solid units of 200A batteries at 48v
That large volume of batteries are well balanced using looping apart from using 5 equalisers. This prevent one battery running away from others. They dip and grow charge almost equally.

Malevonent:
Is there anything i can do to save a runaway battery?.
Voltage gets to 15.6volts, while other batteries in series are 14.4volts.
From the graph we can see the history, will upload another image when its really high.

I have added a balancer last week, but nuthing appears to be changing

Battery C is the bad battery with the voltage spikes, green graph too.

I'm only working at probably importing one, not DIY yet. I feel the imported could serve as a pedestal for future DIY.

Talking about electric cars in Nigeria, we just may have keyed in early than we anticipate with a new entrant into the fray. My statement is safely assuming ignoring the Hyundai Kona which is from mainstream car maker and with a base price on the high side.

Sorry, won't be able to post the link as the 5tvpid bot struck again with the main account concerning this same post.

Tubular / flooded deep cycle battery maintenance distilled water & electrolytes now available!

Provided the specific gravity of Electrolyte used is within what the battery type and brand allows, there is no cause for alarm on whether you top batteries with either distilled water or with Electrolyte.

The reason distilled water are used for top up is because, during the electroysis (when battery is charging and discharging), what escape is water vapour and not the ions contained in the Electrolyte.
The ions migrates and sticks to their respective electrodes.

The water vapour that escapes makes the indicator level drops. As soon as distilled water is used to top up, the Specific gravity of the entire system is kept constant.

Cultivate the habit of buying Electrolyte and distilled water from SMARTCELL and you will have nothing to worry about..


Direct from chemical industrial plant ! Place your orders now !!

It has been a while I touched a flooded battery but I am pretty sure you cannot randomly top up electrolyte after the initial fill up to commission the battery for use.

Electrolyte and distilled water are not interchangeable as far as I know.

If you were trying to rejuvenate a battery, one may add fresh electrolyte after first dumping the old fluids and 'flushing' the cells a few times or if there was some liquid spillage and the SG needed to be restored to spec one could add the right amount of electrolyte.

See a clearer graph showing the voltage spike. This lasts for about 1 to 2 hrs, just before float.
Batteries are about 1yr old, this bluetooth ha12 balancer installed barely 1wk ago

Damn, that's a huuuuuuuuuge bank of batteries. What make is this? If you have time you can share your schematic of your wiring.

efuro:
Aaah it is nothing special. I got the looping idea from 24v fangpunsun battery balancer.
And tried it. Few months thereafter, I realised that Oga Niyiomolyunade understood the trick too because
He elaborated on it. He specifically said batteries will work like a giant battery bank. He was very correct. That was my experience too.
Coming to schema
At 48v, you have 5 pararell of 200A batteries making 48kwh of well balanced storage.
Just loop wire at every point of 12v , 24v & 36v across the 5 pararell. In my case I got 10mm wire for the looping
This looping across 5 pararell ensures that at each point of voltage eg 36v is 36v irrespective of place it is being pararelled whether it is string 2 or 5. Literally, looping balance out voltage vertically while equalisers balance out horizontally within each string.
Being DIY am pretty poor with explanation but I hope this suffices.

Edited
Mind you I said well balanced storage because my maximum over night need is just around 40% of the capacity (or 90% for 50% DOD rule for LA batteries which they're ) when on air conditioning. However, when not and it is just fans and lighting points, the bank is 98 to 100% charged the following morning. The daily cycle continues hopefully for the next 3yr having spent 3yr head on already. For now no fancy of lithium technology yet. I still dey ported to LA like the creator of this thread. So help God!

300 kilometers mileage on full charge ain't bad. And 2hrs to full charge from zero is manageable for a van. I also think 5 years battery lifespan is a little too short for comfort. But it's a good start nonetheless.

One good thing I noticed about E-vehicles is that a lot of small startup companies are entering the niche, some even measuring up to tesla performance in speed, mileage and recharging duration. This is aside from guys that will even prefer to DIY rather than buy because main requirements are an electric drive training, batteries (which China is happily providing for the world), a motor speed controller and a light body/framework to house them. You can add other accessories as choice based on the level of luxury desired.

The import of this is that prices will likely be down to very affordable levels.

Thanks a lot for your explanation. Please can you add schema to help buttress this explanation?

Has anyone tried Solar generators especially Qusa solar generator?
What do you think about it?

Polaris1:

For charging phones and a few low wattage lights. Good.
For anything more demanding. Useless.

NextDayPP:
I need all in one solar street light.

generationz:
Does anyone have this setup for a whole house set up?

dapsyra:
These are bogus Chinko cell. The capacity is highly overstated. Don't touch it even with the proverbial long spoon.

generationz:


I see. I took that picture from Google, btw. Do you mean anything set up with those tiny cells even the good ones won't last?
