You wrote 200ah battery 30k?please which type and brand?

i dont know until i call to confirm which brand is available. They are not brand new batteries

ReLaTE:
Thanks a lot, where can one get these since am not in Lagos.

na for lagos me i sabi, i dont know of any other place

ReLaTE:
Good job u are doing, keep it up.
I hv a used ups 650v blue gate (1 battery) and another used 1500v blue gate(2 batteries),I want something that can power my LCD TV,decoder, standing fan and about 4 energy bulbs for up to 6hrs after a full charge. My LCD is 90watts,Standing fan 70watts,decoder 25watts.
Pls suggest things to buy and how much it can cost in total.,about the UPS,which one will be good for the setup.

the 650va ups will do the job.
20amp smart charger= 7k
200ah battery= 30k
black and red wire and celotape = 300naira
if u have extra cash like 3 to 5k u can buy a brand new standing fan of 35watts or below to get more time and get an energy savings bulb of 15watts each and switch off the ones u are not using
Please dont plug the industrial fans to it, big or small industrial fans like OX etc , should not be plugged to the ups

hotmolo:
thank you so much. i just checked my 2 old ups. 1 is 650vac while d second is mercury 220vac. is d 220vac ups completely useless for this setup?

how many batteries does the 220vac use ?

.

Why dem no fit carry some of these prisoner go backyard for police station and shoot dem?
They stil go back to armed robbery when they are released from prison

These are protect features of the smart charger

overheat protect
short circuit protect
Low pressure protect
reverse protection

hotmolo:
pls sir, wen i buy d 20amps ba3 charger do i need to do any special settings? like where do i turn d knob to? secondly, from d pic u showed on how to connect in parallel, will d ups cable also be connected to d same terminal d battery charger is connected on the battery? i ask to avoid wrong connection.

if u have a 40ah and below battery , u wil set the knob to 40, if u have above 40-80-100ah, u will set the knob to 80-100ah and if u have 120ah and above battery, u set at 120ah.
But if u have a 40ah battery and u set the knob to 80-100ah, the charger will charge that 40ah faster.
Yes on ur second question
buy a 2.5mm flexible wire at oshodi, one yard is 200naira, buy in red and black color so that u dont mistakenly connect wrongly, if u connect it wrong ,that ups is gone but the smart charge will be ok because it has
reverse protection
and so on, get more info from the chargers manual

Its a small world

If u connect 2 or more batteries in pararell to ur ups or charger ,to avoid one battery fully charged before the other or 1 battery supplying power more than the other instead of supplying equally at same time,
SOLUTION: after connecting the batteries in pararell ,
battery A (black wire) goes to ups black.
Battery B (red wire) goes to ups,
same applies to charging,
ur 2 batteries supplies current evenlly to the ups and charges evenlly too.
Na that site i learn am 7months ago, when i discovered dat one battery dey die before the other,

.

for those who want to connect their batteries in pararell connection
if u have a 100ah battery and u feel u need longer time on ur battery u can buy 1 or 2 more 100ah batteries and connect in pararell. There are two types of battery connection to an inverter or ups (series connection and pararell connection)
like mine, i have (2) 12v 18ah and ( 2) 12v 42ah and (1) 12v 40ah
18+18+42+42+40= 160ah is what i have.
My connection is in pararell cos my ups uses just one battery, series connection is for ups that uses 2 batteries inside, pararell connection wont work on ups that uses 2 batteries and if u connect batteries in series to a ups that uses one battery, that ups will blow up and die
See photo below on hw to connect in pararell.
All photo are in pararell connection,look closely to the cable that goes to the charger or to ur ups

Oga Ceejay,good job u have done.i contacted the Battery seller at oshodi and he only has 18ah battery,will it perform well just to power a 30 watt appliance?

yes ,18ah will power 30watts appliance but not for long, i will advise u to wait till he has bigger batteries

My thread on how to create a locally made inverter has been moved to SCIENCE & TECHNOLOGY, so when u open the link below ,bookmark the page, so that u dont miss out, i will update this thread here for a week for those who are not aware, i wont answer any question here, all questions should be posted in the right thread . Link below God bless you all

vansledge:
OP, how can i know a good fairly used btty (any mins of testing?) my location is not lagos...
thanks

theres this meter that is used in reading batteries. The guy at oshodi has it,if only u have a trusted seller who wont decieve u like alaba boys, i only know of 2, the guy at oshodi that sells tokumbo and the guy at ikeja that sells brand new, there a lots of trusted seller and at the same time bad ones are among them,

OP pls answer this question... thanks

i dont know, u have to search it on google

Cjsmack:
Pls Ceejay what's the output waveform of your 650va ups?

ur answer is here on this website, every other interested nairalander who wants to know more about bluegate 650va ups waveform or features should click on this link below

Ofèmmanu, i shake nyash for una

bishop4life:
You have a point. But mind you that most appliance makers put all that into consideration. As long as you don't overload your ups the components won't over heat and also won't get burnt. It's just like some local djs using fan to cool their amps, but most gud djs go for good power amps and so don't need the fan. So before you go on your project run a check on your intended power consumption and get the right appliance for the job. You won't have reason to complain later.

i am in love with ur explanation

dollarnaira:
Ceejay please is there a higher capacity charger for 100amp n 200amp deep cycle ba3s?If yes
please how much plus fone no of seller/address.Tanx sir

check page 1,2 & 3 his number is there
he has 10amp charger= 5k
20amp charger = 7k
30amp charger = 10k
all of these charger will work for 100ah battery
the 10amp charger can charge upto 100ah or 150ah.
The 20amp can charge up to 400ah.
30amp charge up to 600ah or 800ah
dont get me wrong, even the 10amp can charge 800ah batteries but we are looking at timing ,if for instance a 30amp charger charges a 400ah battery fully in 4-5hrs, a 10amp charger will charge the same 400ah battery full in 7-10hr
so u consider the time frame nepa dey give u light in a day

Bosc:
I was meant to understand that you need 3 things.
1. UPS (without battery)
2. Smart charger &
3. External Battery
you will connect the battery taminals to the UPS and the smart charger at once and plug both UPS and smart charger to electricity (NEPA)
How do you integrate the smart charger into this system?
Answer: ur smart charger connected to the battery terminal + and - same as u connect from ups to battery

(Pardon me for asking this silly question, its for clarification purposes)

@ceejay80s

u are not asking a silly question. We all are learning here, even me that started this thread have have learnt athing or two here.
I have edited ur post when quoting . Read it, thats the answer

martinz1:
What you said might be true
But the fan thing is necessary to keep the system cool
For security reasons not to burn the internal component of your ups and also to prevent fire out burn.
I've never seen an inverter that doesn't have internal cooling fan
Even the 20amp charger u r using has a fan inside
I deal on inverters so I can tell u that
There are transformers and hot transistors in those devices that needs cooling if loaded and used for long period of time.
U can also make more enquiries online about using ups as inverter they also advised in the same issue

very true, but that cant be a problem, my mini audio amplifyer keeps over heating and always burns the sound ic, all i did was go to oshodi and bought a 12v small fan ,connected it to one big capacitor inside, i glued the small fan insid the amplifyer and covered ane screwed it. If i put on the audio amplifyer ane the fan start spinning and cooling the ic and transformer, u can do same if feel ur ups will overheat, just go to oshodi, get a sizable fan that will sit inside ur ups comfortably, conect the fan to the big capacitor and face the fan directly at the ups transformer , if u cant do it, look for any electrician in oshodi market, dem plenty, dem no go charge u pass 200naira unless dem see say u be novice, buy the fan ur self first

Please Note:
i read posts of some of my fellow nairalander saying that a 650 ups might overheat when used for more than 8hrs, well its not true, i have done my home work and i am telling u dat a ups can stay for more than 24hrs..
E.g: my boss stays in ibafo and resumes 8am, his desktop ups is turned on arounad 8am and he goes home by 10pm because of traffic, lets calculate, a ups that was turned on at 8am and turned off at 10pm, why e no overheat and blowup?
If i dont have anywhere to go to on satureay,mine is always turned on 5am and turned off 10pm or 11pm.
Dont get me wrong, nepa fit take light at 10am, then bring back by 2pm and take it again by 5pm and bring back by 9pm.
These take & bring light at every 3hrs charges the battery and the ups is always on at
that time.
From 5am-10pm or 11pm is how many hrs that my ups has been on. 17hrs !!
Hope u all understand
