Hi all 4S 200ah lifepo4 cells (sinopoly) with JBD100A BMS. Charged with solar (MPPT allegedly) Im after some advice regarding the tweaking of the BMS (overkill app, but JBD BMS) settings. I've attached: 1) current settings 2) cell undervoltage alarm from last week (delta 0.078v) general...

Hi all I am building a 2x 8S battery banks using 16x 3.2v 320ah cells. (8S,2P) I have top balanced half the cells doing the following: series charge in 8s configuration to 28v, then parallel them to 3.6v (my DC power supply only shows to 1 decimal point so didnt do up to 3.65v) until the DC...

hi all Im looking for some best practice guide lines in terms of mounting the physical cells for anti-vibration in a van. The cells I am using are the blue aluminium/plastic cased ones. My system would be a 8S2P 320ah 24v cell system. In my van I have 1" polyiso floor with 1/4" plywood over...

Hi y'all My main solar system in my sprinter van will be a 24v system. From there it will feed into my AC system through a big inverter. However I have a few small loads that run off on 12v. The 24v system is 2x banks of 320A lifepo4 cells in 8S with a JBD BMS. But the piggy back system...

Hi I ordered 16x 320ah cells liitokala from AliExpress I'm in the process of trying to charge them. I plan on doing 2x 8s 24v banks but I'm charging them with a 12v charger first in 4s with a JBD BMS. Here are the voltages so far before they got cut off from the BMS. When they arrived they...

Hi all I have some questions concerning BMS. My system will comprise of 16x 320ah (allegedly) lifepo4 batteries from aliexpress into a 12v, 4S4P 1280ah system As I have 16x cells I am thinking of dividing 4 cells into a bank with a BMS for each bank, with the 4 BMS' wired parallel to each...
