The tin is a no go area now o.
With current exchange rate it costs over 122k.
This one had been with me for over 4yrs.
Omo!

Adjustable charger
You mean with buck converter?
Technology MarketRe: Diy Lithium Ion Like-minds by Veew: 5:42pm On Apr 26, 2025
dollarnaira:
Yes roughly.
Freezer ran for about 8hrs, completed with powerbank charging till it gets to 8hrs 33mins.
Really great for a 24p3s.
I'm planning on building something similar.
What kind of charger do you use please?

Now you have a working system.
Active balancer light OK.
Ensure u don't go below 11v during discharge.
The bms cut off discharge around 11.8v prior to installation of the balancer, I'm still observing.

@veew
You just dey stress yourself up and down grin.
6ah 4s system is too tiny to slap a whole 50a bms.

Get an active balancer which is the most important to prevent voltage inbalance.

Charge via a buck converter set to your desired voltage and have peace of mind.

By the way, will you use inverter for this set up? What are your loads?
Hahaha 😆 😂 I'm not the original builder boss, I bought it at a giveaway price because some of the cells were dead. I bought replacement cells and decide to use it to learn and so far I've really learnt alot.

I got to understand I can't even use half of the 50amp rating on the bms with my current load; for now I use a 200w mini inverter and my loads are wifi router and charge phones/ laptop.

Yes I got the a 4S 5A active balancer installed yesterday, I noticed the light on the balancer is always on... is that normal?

Another modification I did is increasing the parallel cells to 4S7P so a total of 28 6ah cells.
Since I have a 5A active balancer installed to handle the balancing, will it be a problem?
Technology MarketRe: Diy Lithium Ion Like-minds by Veew: 10:15pm On Apr 07, 2025
I need 4S active balancer. Anyone here selling within lagos?

Hope you included a small heat sink for the diode?
Because 10A at 1V drop out is 10W and it's a lot of heat power for a free running diode. The voltage drop is topical for diode (0.3v to over 1v depending on lot of factors). The diode should fix the reverse current issue, perhaps it's faulty or not properly connected. Finally, the 13.7v would not be a problem for the BMS.
I was hoping the fan inside the charger would expel the heat from the diode.

I did say it stopped the reverse current, but I think the charging might be slower now because of the voltage drop.

A >10A Schottky diode like the MBRF20100CT. You need to mount it on a heatsink as it gets warm/hot when delivering current through it.
Yes you're right, I noticed this.
I'm planing to extend the wiring to place the diode close to the fan of the charger since the fan on the charger is always on while charging

Thank you sir

Buck converter controls the output desired voltage.
So the converter should be set to 1amp?
Technology MarketRe: Diy Lithium Ion Like-minds by Veew: 7:28am On Apr 06, 2025
officialfestus:
get a 10A rectifier diode.
I got the 10a rectifier diode, open up the charger and solder it to the positive wire. It did stop the reverse current flow but when I take the voltage reading from the charger mouth, the voltage dropped from 14.6v to 13.7v. I understand it's due to the internal resistance of the diode but I want to know if that will be a problem for the BMS on the long run

Yes
I don't understand the "charger via converter" part. I'm still a newbie
Technology MarketRe: Diy Lithium Ion Like-minds by Veew: 5:22pm On Apr 04, 2025
dollarnaira:
Get a charger via converter at 1amp.
Sorry I don't understand this.

And can I still use an active balancer together with the passive balancer on the bms?
