Figured it out, while on any of the voltage adjustment screens, quick double press....then hold to increase. Not documented nor intuitive, hopefully this may be of use to others. BTW, my tester did shut off test when LV was reached.

Dooh....thanks :)

Perfect! Thank you again!!

Well this is not good...did two full tests, started with a top balance to 3.6V then cut off at 10V for the pack. Only achieved 325 AH which is 103% of the marked 314Ah rating on the cells. Now how to hold eelbattery accountable for their deception

I am planning on using alternator charging for backup in less than ideal solar generation situations, I may have been somewhat impetuous in my purchase and am going to spend some more time mapping out the entire system before I end up piecemealing everything up.

Thanks for the information. Here is the system as I see it. Question: Will I still need a shunt to monitor something and if yes, where would it be placed?

I don't think your comment about the 12V panel is correct, but please feel free to educate me if I am thinking about this incorrectly. Here is the specification on the DSSR20. Also I generally like tinkering and at least for now can integrate the data from the SBMS0 into the Home Assistant...

FWIW...I just ordered the Electrodacus SBMS0 (which replaces all previous models) along with 3 of the DSSR20's for solar management and BMS. Highly configurable and robust/affordable. I would encourage anyone to have a look, very fresh approach to setting up a good solar system.

@jwelter99 with assistance from you and @snoobler I finally get it and believe I have the proper configuration shown in my last buss bar picture. Do you have any wisdom to share regarding the 16 lead BMS?

Not yet...but from the videos I have watched from Will, he has stated on multiple occasions that suppliers are dishonest to label/advertise/sell batteries or cells with a higher than mfg. stated capacity. Also...I would have but my load tester is fried and my inverter failed as well so I am...

Thank you for your insights, I am still learning and with what you have shared will reconsider my BMS choice. Here is the intended layout for verification.

I am still a bit on the fence, but given the integration and UI features Victron is a front runner...but $$$. I am also looking closely at the Electrodacus SBMS120 for the MPPT and also using it for the BMS, but he only builds them via Kickstarter campaigns and currently I am unable to get one...

Thank you again...interesting and proves that I have additional education to undergo. Perhaps I will use it for monitoring and BMS and then utilize one of the Electrodacus remote on/off outputs to control say a Victron MPPT charge controller.

Sounds good...any recommendations for a high quality BMS with a functional temp sensor (or 2)?

Once again, thank you. Would the best scenario be to eliminate the buss bars between the groups? Would that more evenly distribute the load? I still struggle to understand the current flow.

As stated above, purchased from SANBEN Global Battery Store. Here are some pics showing swelling and lower than advertised capacity.

On January 15th I purchased 16 cells from eelbattery that had this description on their website: However, the cells that they delivered are marked as LF314 with an Ah rating of 314: I sent an email to eel battery on January 23rd (the day that I received the cells), stating the...

All cells were top balanced to 3.65V, let to rest for about 20 minutes, then set at a 20-22A discharge rate ~0.1C (highest my tester would go), and cutoff at 2.5V. The recovery you see to 2.56 in the picture above is the cell bouncing back a bit after the discharge cycle completed. I have not...

OK so with further research the JK BMS's can be integrated into Home Assistant, thank you for that video and lead! If I may ask another question...there seems to be competing opinions on BMS pros/cons of using multiple. If I go with a single BMS for the 16 cells I cannot figure out if each...

Glad I found your post! I have 16 cells and need to configure a 12V system, so if I understand you correctly a single BMS that does not monitor each cell individually will be a robust setup? Would I configure the cells as 4S4P? And if yes...what would be the best buss bar configuration to...

Great...so the batteries should arrive tomorrow, then the BMS's in a few weeks from China. I would like to have ppl. verify my config. Thanks to all who helped guide me.

Looking for buss bar advise as even though it should be simple...I seem to struggle with the logic/calculations. I am putting this 4p4s system into my camper thus the 12VDC requirement. As the title states...these are 200Ah prismatic plastic case cells. I will be going with the "squarish"...

Thank you for the information. So it sounds like I would make 4 seperate 4S batteries and connect them to the DC buss. In this configuration I would require 4 BMS's...correct?

I have (finally) pulled the trigger and have 16 320AH cells headed my way. I am building a 12V system for an overland rig that I am designing and building from the ground up. I have a Victron Multiplus 3000 12V Inverter and will be using an Electrodacus SBMS0 for battery management and...

Thank you for the quick reply! Your explanation of the center two rows carrying less current does make sense, thanks for that as well. I went back and revisited one of Will's videos here: Bus bar Stacking Tutorial and it looks like the most robust solution would be series everywhere...as...

I also purchased these (in dispute now) and even worse is all 16 cells were delivered swollen and only delivered 140-174 Ah. When I purchased the page clearly stated 100% Ah guarantee (I lucklilly did a screen capture to prove it) but now their page only "guarantees" 170Ah. Total rip-off.

Thank you for the input on the terminals...however I would appreciate not hijacking this thread as I am trying to solicit some support perhaps from Will to review and maybe apply some pressure to eelbattery so I can get to a solution for them mis-representing the Ah of the cells that I purchased

OK This is what I have which makes sense to me but wish for a learned set of eyes:

Just purchased one of these through Will's link. Testing a single LifePo4 cell and want to set the Low Voltage cutoff to 2.5V. However at that screen a long press only sequences the values DOWN, it is currently at zero and for the life of me I cannot figure out how to raise the LV cutoff. I...

Makes sense....

Could I use a 16 lead BMS to enable monitoring/balancing every cell?

Good point...This is the one from Will's Amazon link that I got: Maker Hawk Load Tester . I tried all sorts of combinations of triple and other quick presses, no change in the menu or ability to raise the value.

3rd test...almost exactly the same, starting voltage shown down to 10V

Indeed...the store I purchased from was SANBEN Global Battery Store. Very dishonest and misrepresented the product (swollen batteries that only deliver about 72-84% of guaranteed capacity) AliExpress stepped in and the seller has agreed to full refund....but apparently I am on the hook for...
