Good morning, please can any user of valtech batteries kindly assist me in making a decision on valtech 3.6kVa 24v battery

bassdow:
currently designing a system similar to what the likes of sunKing offers. it's a payAsYouUse project for a client.

Obnoxious2001:
Energy as a service (EaaS)?

Valto:
. we have been in this business since 2019 , and have been an ardent follower of this great thread since it's inception,in the days of GeorgeD and sathob!
several hundreds of people from this thread have bought and have been using my battery for several years now. also we keep improving the quality of our batteries as the times goes. all my alternate accounts are affiliated with my business name. we don't need too much convincing, our track records speaks for us. cheers.

Dem think say the "FTA" for the thread name na meme. Who neva track birds with 3 lnb on top 0.9m no go know

omo those days eeh. there is no type of dish and LNB that i don't have. from 60cm dish to 1.8m dish. we tracked wetin no good from MBC to baracuda sports TV. i still have plenty satellite decoders, strong, QSAT, E.T.C

bassdow:
...and tomorrow now, person wey be say na through mass promotion e manage own starTime decoder wey e no even too dey spend money on, go wan follow you dey argue some kind things.

A lot of us don't even know there was a a time DSTV distributes those magazine sized booklet on monthly basis. The days of Nitel and their plenty black wire sprawling everywhere...

not really. Accoridng to client, they want to sell electrocis of different kinds with option of downPayments - where they pay an agreed amount till the costs complete and should they default, the item would be remotely disAbled and if they still don'tt respond, it gets Repossessed

Obnoxious2001:
Have you developed the hardware?

Tracking Nilesat and Hotbirds before the advent of dstv. Don't Play!

Tdoctor:
This is what I came up with. Thanks to everyone who helped me decide.

My thoughts on DIY Lithium
1. It is stressful. Only embark if you do not mind the stress. It is NOT a walk in the park.
2. You must know basic electricity principles. If you do not know how to check for continuity with a multimeter, it may be best for you not to continue. Read well and research before embarking.
3. First builds come with mistakes (I did not top balance, so my BMS is currently being overworked. Thinking of opening the case to charge some cells individually. Tips will be appreciated).
4. If you do not already have tools and materials from other projects, it may NOT be cheaper than buying, for the first build. I could cut down costs because I had materials from other projects e.g. 250A MCCB.
I cheaped out on the terminals; I used the hanger that came with the electric cabinet.
5. It is FUN and you will learn a LOT - wiring, behavior of materials, tools, etc. Subsequent builds will be much faster.
6. Before you use cheaper materials, do your research o. I abandoned the wooden box I created and went for metal after suggestions on this thread, because this is my first LFP build. Mrreed and Valto can use wood because they are experienced and have some design secrets first timers do not have. Safety first, if you are a first-timer.
7. Double-check everything. I went through all the screws again before deploying, only to find out two were not well tightened.
8. Youtube videos from foreigners are mostly useless when it comes to procuring materials. A lot of the things they have there, we do not have or are difficult to source (e.g. fire-resistant cement case and fire-resistant graded wood). Seek local threads for guidance.
9. Eat well before embarking. Drilling and cutting are not easy.
10. Stop working whenever you are tired, before you drill or cut yourself.

You are on point especially top balancing currently facing top balancing issue because getting a good DC adjustable power supply is vary hard pls where did you get your battery casing can you post the link thank you

dollarnaira:
When buying cells, ask the seller to balance the cells for you before shipping. If not done by the seller, fully charge the cells in series and reconfigure again in parallel for few hours or days to naturally balance out without the help of an adjustable charger.

Thanks but I just connected in parallel without charging is there any side effect to that

bassdow:
should in case you find it difficult getting a casing, you could just meet any welder, ask them where you could buy (New or Used) metal plates. Buy the required thickness (tell them what you intends doing with them and they would recommend you a suitable thickness); give the job to a welder to create the casing to your liking.

That's if you're scared of using wood.

Mind you, building a high capacity battery such as the kind done by @tDoctor isn't recommeded for everyone as some sort of prior knowledge is required. No go create wahala while trying to save pennies.

Tdoctor:
-
I agree. When I started, I did not know much, but have learnt a lot over time.
There are things to consider when building a high power battery:
1. Cable size
2. Busbar
3. Protection (breakers)

capnies:
Good afternoon great mind's, please whpo has bought something from circuitmall.ng before and how was the delivery

dollarnaira:
What is the initial voltage of each before parallel? Charging each full first is the best option to me.

sirneyo2005:
3.27,3.27,3.20,3.33 also the are new cells I haven't used them since I got them I just left them in the pack also I believe with the knowledge I have gotten here and YouTube videos coupling it won't be an issue. Concerning cable I have prepared 25mm to be used in connecting the bms, 2by 10mm awg will be used from panel to a 50amps breaker would have used a 63amps breaker but charge controller is 60amps

thanks. But like wetin and wetin be your finding that discouraged you? Apart from being pricey. Abeg another person wey dey use for farm or other setting fit chip in
