Battleborn rates their batteries as useable Ah, meaning you can use all 100Ah of their stated capacity. Their batteries are closer to a 120AH If you were comparing them to a typical 80% useable LP4 battery. Hence the SOC waring at 5% instead of 25%

Hi - I know this is an old video. But the charged setting should (according to Victron) should be set to 0.2 BELOW the float voltage of the charger. So given lithium chargers charge at 14.4v then once the battery is full, they then float at 13.8v. Thus from what I understand, your "Charged Voltage" Setting should be 13.6v?
0.2V below FLOAT if you do not have solar MPPT controller feeding the system, with MPPT controller charging batteries it should be 0.2 below ABSORPTION. This is after BMV700/712 charge controller manual (point 2.3) from Victron www.victronenergy.com/upload/documents/Manual-BMV-700-700H-702-712-EN-NL-FR-DE-ES-SE.pdf : "The BMV synchronises too early In solar systems or other applications with fluctuating charge currents, the following measures can be taken to reduce the probability for the BMV to reset prematurely to 100 % state of charge: a) Increase the “charged” voltage to only slightly below the absorption charge voltage (for example: 14.2 V in case of 14.4 V absorption voltage). b) Increase the “charged” detection time and/or decrease the tail current to prevent an early reset due to to passing clouds. See section 4.2.1 for set up instructions"
fullmoonadventureclub the tail current. I have the lion energy’s UT1300s also do you know what voltage there suppose to be at when fully charged to 100% by chance ?
@@fromtheroadwithrobert I believe the tail current should be the same as I showed in the video but I'll try and double-check that tomorrow for you.. The charging voltage of the Lion energy ut 1300 is 14.6 volts
On battery settings page "Discharge Floor" says 50%. We cannot find any information anywhere about Discharge floor. We have 2 battleborns. We think the floor should be 20%
Off the top of my head I can't remember setting my discharge floor. But yes it should be around 10 or 20% with Battle Born batteries. You may want to call customer service and ask them how to set that up because I just can't remember it off the top of my head and I am not at home.
@@fullmoonadventureclub Thanks for reply, that is my assessment too but I will double check w/ Battleborn customer service. Your video was very helpful.
I would love to help. However, I do not have a 24 volt system in my RV nor do I have Battle Born batteries. I wish I could be more help but I simply don't have the equipment to cover the parameters of the test you request. Jim
I know I'm writing this post like this is a forum or something. If someone knows a good lithium battery rv or van life forum page let me know. I can post there or find more answers there. After watching this video, I was wondering a few things. my battery specs say to charge at 14.6 but my mppt charge controller when set to "lithium setting automatically chooses 14.4, I was thinking to increase cycle life even though I loose a little capacity can I set my battery to charge to 90%. so i was thinking of 14.3 instead of 14.4, but now looking at the specs maybe 14.4 is already 90%. Since like in the video my specs say 14.6. But either way I drop the parameters on my controller to a few decimals below what fully charges the battery so it ends up charging to 90%, then I am wondering if it will it still balance since bms is probably top balancing. Top balancing means the BMS needs to be 100% charging so it can continue to charge lower cells as it vents extra charge off cells that are get to 100% faster than others until they are all at 100%. Not that these batteries go much out of balance, but its probably still important to let the bms do its balancing job once in a while. So wondering if anyone has thoughts on if there are balancing cons to charging to 90%, even though 90% increases the life cycle dramatically and maybe i could get 6000 cycles. There are different types of bms and there is a newer kind that does continual balancing where it takes energy from higher cells and gives it to lower cells. in that case it would not matter if I did not fully charge to 100% I also do not understand why the renogy mppt controller even when set to lithium setting, has default a charge limit voltage set to 15.5 volts, where as most of the other settings are automatically set to 14.4 in its parameters. Will Prowes who makes a lot of videos says to set charge limit to 14.6 but that is for a system set to charge to 14.4, so maybe his logic would mean i should set mine 2 degrees above whatever my charging is set to. so if I have 14.6 as my charging setting then my charge limit should be 14.8. but if you look below the default of my charger being charge limit of 15.5 seems way high. I think Im going to change that charge limit setting to 14.6 and leave the boost charge and float charge at 14.4 for now. i see no reason why the battery would get up to 15.5 because the internal bms would not allow that. Also a minor questions i have if I should follow Will Prowes' advice to lower the floating setting. some people say to change mppt controller float settings to 13.6 for lithium. on his controller he lowered it from 13.8 to 13.6 as also a way to get the most cycles out of these batteries. but 13.8 is listed in the battery specs for float voltage so that makes me think its the bms is already managing that because my mppt has float set to 14.4. But maybe in the specs of battery they mean to tell you to float at 13.8. I do not know if bms manages float, but i assume it does. In that case setting float to 13.6 on the charge control would probably overirde the 13.8 setting in the bms my battery is brand new only been in a week and it has been raining running a fridge I have not yet seen it made it up to 100%. but today is sunny. I have built in bluetooth monitor in this battery so I can see right where it is at and I higly recommend this battery because of that. so today it should read 100% full and if for some reason it only charges in full sun to 90% on 14.4 settings then I will know I should change it to 14.6 if I want 100%. This is a real learning experience. If you look at the pasted specs and renogy default settings on the charge controller below, any parameter adjustment suggestions would be much appreciated as I think this subject is not really covered in the instruction manuals or websites of these product. here is the list of the parameters of my battery the Torque Power brand followed by the default lithium settings on my rengory mppt 20amp controller Toroup power 12v LifePo4 100ah battery trqpower.com/product/12v-100ah-lithium-battery/ Voltage: 12 Volts DC Capacity: 100 Ah (1,280 Watt-hours) Weight: 26.4 lbs (12.0 kg) Size: 12.5×6.5×9.25 in (318x165x235 mm) Long Life: 2,000 Cycles @80% DOD (on the website in another place it says 3,000 cycles @80%) Operating Temperature: Discharge: -4°F - 140°F (-20°C - 60°C) Charge: 32°F - 113°F (0°C - 45°C) Charge Voltage: 14.6±0.1V Discharge Cut-off Voltage 8 Volts DC: Slow Charge Current: 10A for 10 hours Fast Charge Current: 50A for 2 hours Float Voltage (Standby): 13.8±0.1V Max Discharge Current: 100A / 350A (3s) Self Discharge Rate: ≤1.5% per month This is the list of what my Renogy charge controller parameters automatically dealt to when I choose LI on my charge controller. I must assume this is what they think works best with their renogy lifepo4 batteries. Although I can adjust these parameters in the using the renogy charge controller bluetooth thing and its app, i cannot turn off any other them that i think unnecessary to have, but some might be turned off since it has -- instead of a number: Battleborn website says lithium does not need equalization or boost. so that makes sense, and anyway those are all set to 14.4 so that voltage goal I think is the main way this mppt charger is operating high voltage disconnect 16,0 charge limit voltage 15.5 Equalize Charge 14.4 Boost Charge 14.4 float charge 14.4 boost char return volt 13.2 over disc reture volt 12.6 (they actually spell it reture in the app?
