As an update, the 50W balance charger I got didnt work. I tried charging with low current (0.5A in normal serial configuration) and the cells didnt balance successfully. I tried connecting the BMS pins to the charger directly to balance the individual cells and the charger error'ed out with low...

I hope so. I think the cells are healthy, just not very well matched. If I can top balance them I should be able to get the capacity I need.

The way I understand it, the balance charger uses the bms to balance the voltage of each cell as opposed to charging through the main leads. Technically it should be possible since the BMS has a parallel connection to each cell while the main leads provide a serial connection for faster...

Yep! Thats the one! Ive attached a couple of images from the most recent charge cycle (cells actually got to 3.4V) Looking at the specs of the charger I ordered (Tenergy TB6-B), the current can be customized between 0.1A to 5A. Should hopefully do the job! Next cycle Ill charge it with the...

I only recently received the battery and have had this issue from the get go. I am trying to top balance the cells hoping that afterwards, they would charge more evenly. Ultimately, my goal is just to be able to get the full 80ah out of the battery. Also, I worry that if I constantly fully...

Thank you very much for the reply! All I know about the BMS is that its 80A with Bluetooth capability. I have been using the app on my phone to monitor the battery over bluetooth. When charging, the BMS overvoltage protection kicks in when cell 1 reaches 3.65V, with cells 2 through 4 at 3.4V...

Hello all, I have a prepackaged 12V 4cell 80ah lifepo4 battery if it has a BMS. I am trying to top balance the cells and I was wondering if it is possible to do so using the balance chargers without taking the battery apart to reconnect the cells in parallel. I am still unclear how the BMS is...

Absolutely, but that would involve taking it apart (removing the blue seal wrapped around the battery) which would void the warranty. This would be much easier if I had gone the DIY route. I am wondering if using a low power balance charger (eg. 50W Tenergy TB6-B) to try to resolve the issue...

Hello everyone, New to the forum and hope that someone can help me get some direction on my recent issue. I am trying to decide the meaning of the issues I am having with my new 12V 4 cell 80ah LIFEPO4 battery that I purchased of Aliexpress and how to best proceed while Im still able to dispute...

Hello everyone, Just joined the forum as it seems active and has a wealth of knowledge. I am an electrical engineer but spent most of my career in aviation. I am an astronomy hobbyist and work with solar chargers and LIFEPO4 batteries to run my rig out at dark sites. I have had some trouble...
