BMS Question for 48v System

[zerzuri]

Hi all!

I have a 24v system with four 280Ah Lifepo4 battery groups. In each group I have a 8s 100amp JBD BMS. I would like to change my system from 24v to 48v.
My question is:
1- Can I regroup my batteries while still using these BMSs.
2- If yes, how? If no, what is your suggestion.

I am going going to be using EG4s 3000EHV-48 All in one unit for this project.

Your suggestions are highly appreciated.

Thanks

Oz

No, you will require a 48 volt 16s BMS.

That ?

What BMS exactly? If it is strictly an 8S BMS, then as others have stated, no.

Many of the new JBD BMSs are 7S-21S so can be used for a 16S BMS.

I say this because i looked pretty hard for a JBD 16S BMS and couldn't find one (with features i needs which were modest).
I had to settle for the 7S-21S which required ground 7 of the 22 leads onto one cell which i wanted to avoid.

Thank you for your response. They all are just 8s 100 amp BMS. I will have to buy new ones for each group. Any recommendation besides JBD 7s-21s?

Thank you!

Thank you!

I've been very happy with my JK BMS.

 

[timselectric]

JK-BMS here too.

If i had one i'd recommend over this i would have bought it.
JBD-SP21S001 V1.4 (the new black anodized model).

I have been running one (of 2 i purchased) on a test bench for a month.
One of the key features i required was ability to use XiaoXiang app (same as Overkill app).
Pretty happy so far but just on a test bench, waiting for my system to slowly get built up.

You can't go wrong with JBD or JK.
I'm running 5 JBD, 3 smart (with built in relay) in 16s config (1 was used prior in an 8s config) and 2 4s with no issues.

My experience is with the Overkill rebranded JBD. 100% satisfied
