Phone charger shop owners Don blow o

E-bike lithium battery pack is done, installed and charging. Waiting for the owner to come pick it up

It's 48v so we are building 13S
CONFIGURATION: 13S9P
VOLTAGE: 48V
CAPACITY: 23.4A
ENERGY: 1.126kWh
PIECES OF CELLS= 117
TYPE OF BMS : DALY 13S48V 30A

This e-bike owner needs his lead acid battery to be replaced with lithium ion.

Lithium ion 3S 230A BMS

What's the use when people keep going to bed hungry

SFTW:
Tetralogyfallot are you sure you're ready for business?

A friend who bought from you recommended you and I've been chatting you on WhatsApp to send me Quotation but you're not responding for over a week, nor even picking calls.

Ah ah

sorry for that pls, kindly chst me right now pls.

TO THE POSITIVE TERMINAL OF THE SERIES CELLS

yes boss, just same way.

officialfestus:
is that blue cell really up to 3.2A?

i did the capacity test sir, it's averaging 3000mAh

18650

capnies:
Thanks but if I leave it like that the system will not last, sooner than later the difference in the battery voltages will increase
Please I want to be directed on how to connect it.

same way the bms is connected sir.

Is it for beans? Is it for garri? My brother 2.5m will not build you a 2bdrm flat anywhere in nigeria even if u have the land already. It can just manage to complete your dpc or bim foundation.

Hideout for criminals

Work done!

obinna37:
how much

sold out boss

officialfestus:
how much?

sold out sir

officialfestus:
Package 📦 received thanks @tetralogyfallot

u r welcome boss

These are gotion LFP cells.
The capacity = 15A for each cell
Nominal voltage = 3.2v
Cut-off voltage = 2.0v
Charging voltage= 3.65

dollarnaira:
How many amp?

1Amp

dollarnaira:
Do you have 3s active balancer?

available boss.

7s80A BMS n 7s Active balancer

capnies:
DID YOU PUT PRESSURE ON HIM, I KNOW HE IS ALWAYS BUSY, AND THE DISTANCE FROM HIS HOUSE TO THE PARK WON'T BE CIST EFFECTIVE IF ONLY ONE ITEM IS TAKEN ALONG SO HE WAITS TO GATHER MORE TO SEND AT ONCE

u really understand it wella boss.

okikigsm:
It's good u are looking else where.it is always furstrating.

Some times I laughed when I see come to dm in his responses

engr okiki, even u? Okay o, u know off course how busy n tight the things dey be na.

Trippledots:
I did, and even paid for 2 units. For some reasons best known to him, he returned my money and stopped picking or replying messages and calls after a while of post refund communication.

I hope he is fine btw.

hi bro, it's not available then n u seem to be in haste and the pressure was much that was why i refunded pending itsavailability n i told u so. It's now available. I'll chat u.

This is a very serious burns o. Vitamin c supplements is suppose to be your best friend. It makes healing process very fast.

dollarnaira:
Tetralogyfallot, hmmm I hail ooo.

my oga at the top. I remain loyal boss.

Job is sealed!

Ready for delivery

capnies:
Please gurus can connecting 20 lithium batteries in parallel require BMS. HOW CAN THE 3.7 VOLTS BE BOOSTED TO 12V

yes it requires BMS sir. U connect the 3.7v cells in series of 3 sir. That's 3.7x3=11v when fully charged it will be 4.2x3=12.6v. Hope u understand? If u don't, chat me on whatsapp let me be your guide.

Obnoxious2001:
I was wondering why lumos had a 4s configuration.

simple, their inverters are specially made for them to reach 16.8v.

Obnoxious2001:
House please I need your opinion on. This.

I have been thinking about 4s vs 3s battery configuration of same capacity.

Which is better of to use considering back up.

3s vs 4s for lithium ion is a long debated topic. If u go for 3s the inverter may go off at 10.5 as it's the depth of discharge of most inverter, and at 10.5 the cells still have some juice cos they are at 3.5v while for 4s the maximum voltage is 16.8v but unfortunately most inverters don't go upto that voltage except of course the recent hybrid inverters. In summary, if your inverter can accommodate over 16v then go for 4s but if it can't, u can manage your 3s. Lithium ion powerwalls seems better from 7s n above. But for 12v setup I rather suggest lifepo4.

2kWh, 7s30p, 24v lithium ion built powerwall, built for a client.
