Okay so regarding my electric bike issue and the high cost of lithium battery.

I've decided to get another set of new 5 pieces of 12v 12ah batteries and connect them in parallel to make 12v 60ah.
Meanwhile I have 5 pieces of 12v 12ah installed inside already which makes up a 60v 12ah series connection.

Now my question is if I add another 12v 60ah and join it together with the 60v 12ah I have there before, will the increase to 60v 60 ah or 72v 72ah

I need to know before I burn my scooter brainbox.

Dishtech:

I think the best battery for ebike or any electric vehicle is 18650 lithium batteries. Even telsa uses it because it has higher energy capacity.
480 pieces of 2.6ah of 18650 should give you 59.2v normal voltage and 67.2 at full charge. Which is about 4617.6wh or 4.6kwh.
If you were in Abuja I would have source for the battery and make one for you.

Hello chairman, I want to get a solar inverted installed in my house due. Please can you plug me with reliable suppliers of batteries, panels and inverters in Abuja?

Hello house.

I have a Must 3kw 24v hybrid inverter (PV1800 3024 VHM) connected to 2 units of 12v SLA batteries.
Been using it for a few days now but noticed that the batteries never charge beyond 27.4v.

For those familiar with this inverter, is this normal behavior?

Lemme get your info straight.

1) You have 5 nos of 12v 12ah batteries which you have been using for a while?

2) You want to get another brand new 5 nos of 12v 12ah battery and connect both the old and new battery in parallel to boost capacity?

Do I have it correct?

If yes, then there are two problems

1) It is not recommended to add old batteries to new batteries. If you do, the old batteries will make the new ones weak due to a lot of factors relating to the battery's age differences.

2) Assuming both batteries can be paralleled without issues, you'll have issues with charging. Assuming it takes 4 hours to charge it full using the old charger the ebike came with, you are now left with a charger that will take 8 hours to fully charge the batteries.

When you connect these two batteries in parallel, the voltage will remain the same and therefore it won't damage the motor controller. Because what you'll have is 60V but @ 120AH (the battery capacity will double with the voltage remaining the same).

Before I forget, someone here offered to build you a new pack using 18650, did you not take him up on the offer or the cost is not something you'll like to work on at the moment?

Because I'm looking at the space, I doubt it could fit in another set of 5nos of 12ah batteries unless you are planning on building an external battery bank.

You will be better off going the 18650 route

Thank you, the batteries are relatively new, about a month old.

Also I'm connecting in series and Parallel.
A total of 10 12v 12ah battery, 5 connected in series to make 60v 12ah and another 5 connected in parallel to make 12v 60ah (as external)
I have a 60v 5ah charger

I don't know if connecting 60v 12ah to 12v 60ah will give me 60v 60ah or 72v 72 ah

Also the cost of getting the lithium battery custom built is alarming, I have to spend about 400k to get the desired 60v 30 or 40 ah capacity I desire.

You may need to understand the basics of battery connection.

First, you cant connect 60V 12ah (60*12 = 720watthour) in parallel to 12v 60ah (720watt hour). They may be able to store the same energy, but the voltages in parallel MUST be equal. Since 60v is not equal to 12v, you cannot put it in parallel, if you do the 60V system will attempt to charge the 12V. Also you cannot also add this battery in series- your motor is a 60v motor, a 72v may likely burn the controller and/motor.

I'll suggest you get someone who knows about batteries and connections or you may simply Google "Rules Guiding Battery's Series and Parallel Connections".

Valto:
i can imagine the kind of stress u will go through, just to import 8pcs 280ah cells. i will advise u buy those cells in Nigeria. infact it will be cheaper for you.

I still dey on the matter o, very stressful, but which seller in Nigeria has 280 AH lifepo battery?

mctfopt:


Echoing @Valto's point, you may consider buying it in Naija.

USD rates these days is not as favourable as it used it. Also many banks no longer have great monthly USD rate with many stopping in March.

I heard (not sure) Zenith is now 20USD/month.

Access is now ₦550/$

First bank at ₦499.99

I think the only guys with better rate now is GTB @ ₦490/$ and capped at $100/month...so you'll need like 9 cards to pay for your 8 batteries.

Do not consider using air freight, you are better off buying it in Naija especially considering you are buying like 8.

But if you still want to go ahead, consider using sea shipping ETA like 4 months.

Payment has been a big pain for me,all the cards i tried were rejected by Alibaba , the worst after sourcing for USD at the rate of 585-600 Naira to a Dollar i loaded my Domiciliary account with 2500 usd i went to the bank to make wire payment, and the Bank told me i have to get form M for my own money in My account again o i nearly weep for Naija i left the bank in anger, Since Air freight is faster and the people to handle it will handle Custom clearance i settled for that! thanks for the info but do we have dealers in Lifepo batteries where i can go to get the batteries?

Mine is 450k, the Lithium version ones are around 750k to 1 milla.
I want to sell it, if you don't mind using SLA batteries or plan to upgrade it no prob.

And yes it's available in just 2 places that I know in Lagos, one in Victoria Island and the other in alaba.

If I can deduce from your point, you have 10 piece of 12v/ 12ah,
5series 2parallel should be your connection to give you 60v/24ah.
For the 18650, I can build the 60v/40ah for you at a cheap price. All you need to do is send me the details of your batteries space and the maximum voltage of your system.

Yes i requested and got a USD Debit card for my Sterling bank Dom account and Alibaba rejected the card i applied for appeal Alibaba still rejected the Card so im left with the option of Wire transfer, i just opened GTB Dom account i will try their card to see if it works for future purpose.
Now i used wise.com to make the wire transfer and its still in process i hope it is successful though

wrongest move ever!!!!.
lead acid batteries are big and bulky...the extra weight will inturn consume more battery energy...and you would be only a lil better than you were b4.

2ndly..the new battery pack should hv mimicked the original batt pack..put then in series to give you 60v 12ah as the original...then connect both packs in series. any other thing u do apart from this....you risk serious damage to your person and or bike.

come o...for you to be considering this wrong connection, shows that you need to do more studying of battery connections, DIY dey sweet if backed with knowledge..
