Thanks that was helpful ?

Also on a side note my system is set up 16s2p. I have two separate banks of 16 each with 200amp daly bms then paralleled. I thought it might be a coincidence but that number 6 cell i replaced out with one from my other bank of 16 cells that was seemed normal and then continued the bulk of the...

Hi everyone I have been attempting to top balance my 32 eve 280 cells. My process due to the size has been to use my solar system and bms to charge to higher soc then hook up in parallel and charge the rest of the way with 10amp dc power supply. That being said in the process of charging via the...

Thanks for the replies, I am just about to make my own cords for my ps with 10 gauge and ring terminals I will let you know.

Edit: auto correct snoobler

Hi I just received my 32 eve cells and want to top balance. I have read the pdf and watched wills video, I just have one question. If I am using the step by step method and only using a power supply could I set the power supply voltage to the highest voltage (in my case 32v) which will allow for...

Thanks, any suggestions on daly, smsbms, overkill, helltech, or chargery or anything else I haven't mentioned

Hi am building a battery system with two 16 cell battery banks arranged in 16s2p for a total of 32 eve cells. I want every cell monitored so I have decided to go with two bms. My solar system is a 3.1 kw 48v system with max charging capabilities from my midnight classic 150 at 90 amps. My max...

@ hrtkd Thanks i will shoot him a message. Also to move forward i noticed you mentions the necessity of a shunt between the bms and common bus on the negative side and fuses on the positive side. Considering my system with two bms and 16s2p bank like I drew above what brand and size shunt and...

I am going to go ahead either way and pull the trigger tonight with Amy for 32 lishen cells with welded studs in the terminals for a dollar more per cell as I heard those m6 studs are cheap and can strip. I will do a little more deliberation on the bms options and here more from all of you on...

Ok so again I am new to this stuff but trying to learn fast. So here were my reasons for to larger BMS units: 1) some of wills videos and others on this forum said to better over build bms. 2) in the instance I mentioned, where one bms comes on first or one shuts off and other stays on the...

To bad they don't support a higher amperage rating for there 48v bms

@HRTK Just out of curiosity what bms brand do you run with your 4s2p bank? You have any reasonably priced bms companies to suggest? I would go with batrium but $1300 plus later i would out of budget.

Any need with this setup for additional shunt or relats breakers etc?

If one bms stops or starts up before the other then one 300amp bms would take the entire load fine correct?

Correction Sorry she said it would not work

Also I showed a similar setup to daly electronics rep on alibaba and she said daly can't to parallel or series and it would work? Should I just ignore this. So in this specific setup would two 300 amp daly bms be sufficient as if I am running at .5 c max load for charging or discharge would be...

Would this be battery bank setup be sufficient for 48v system? What you think

I was told in the case of a low temp disconnect or any shut down of one of the bms then the other would take the entire load be it discharging or charging. That being said if the system is designed so that each individual bms of each pack could handle your amp loads of charge and discharge even...

Again in referencing 16s2p where the two separate packs with there own bms are then paralleled after the bms at bus bar locations for both pos and negative.

I am not an expert but from what I have taken from others on this forum there will be issues even if you run the two bms separate of each other. Can anyone clarify if I have taken the information wrong or if there are issues to be had, what are they and what are if there is any, solutions.

Lol darn auto correct.. batrium but barium I am sure will do the same

I am trying to do the exact same and asof now can't find a bms on alibaba that supports parallel banks. I hope someone can chime in with bms that can handle this that is reasonably priced. I have heard the barium can do it but its very expensive ?.

Thanks appreciate it

Also its hard to determine who is telling the truth as you shop on alibaba many will say grade a when you ask but other suppliers for example from Winston or calb or others say thr lishen are grade b. Any thoughts or experiences on grade and brand

Wanted to purchase 16 cells, but they only have the lishen, are these comparable to the eve brand

Well pump breaker was never breaking just batteries bms with SC CODE ( sort circuit protection

30 amps is the wells internal breaker or in this case its got its breakers in a control box. When I put a clamp meter to test current on the wires coming from the pumps control box while running the lead acid bank it averaged out per leg just as franklin says its should around 11 amps to 11.5...

OK well if I go with those cells what about reliable bms rated to handle 160 amps continuous as well as proper bus bar size? Any thoughts.

Considering alibaba pricing i have a good size budget so don't let price stop you from posting if you have any good or better options

Hi I am fairly new to the forum but have been interested and dealing with solar for a few year, so please bare with me. I currently have a 3.1 kw solar array with a midnightclassic 150 charger and a magnum ms4448pae with Magnum mmp175-30d mini panel. This currently runs a small house with a well...

@Dzl In regards to what you were say about price point per ah/$, if unlike most everyone as you mentioned I am not fully concerned about the price per cell relative to alibaba that is, what lifepo4 cell would you recommend for a needed 200ah-300ah capacity at 48v with a minimum continuous...

Correction 16

does your point about the larger a single cell gets the weaker it gets also apply to stationary solar storage for a home? I am interested in purchasing 16 of these 280ah cells and putting in series for 48v system And just want to make sure this is the right choice or going with smaller 3.2vcell...
