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...
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...
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...
@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.
