I have 10 banks of batteries 4-305s 6-280s The 6-280s are charged in parallel all connected to a copper busbar. All have equal length cables, same model JK 2Amp balancer, same compression etc etc I have 1 pack of batteries that always has way more charge in it. It will hit 100% way quicker...

Right now I have a 19kw array. Have 3205AH of LiFePO4 and was wondering what size array do you guys think is adaquate for your batteries? It takes a full day of sun to charge mine up to about 60%. By late in the afternoon of the second day it will be around 100% depending on how much current I...

I replaced 6 of my overkill BMSs with JK 48v 150A 2Amp because of the out-of balance the cells were with the over kills. In all I have 10 of the JKs 4 of them on 304AH Envisions 6 on 280AH Eve On the 6 280AH I replaced the BMSs between Saturday and today. Of the 3 that I replaced Saturday...

Looking to replace my 6 overkill 100A BMS's with some JK's. The top balance is way out of balance on 5 of my 6 battery banks. Those 6 banks are all 280AH cells I also have 4 305AH banks that are JK 150A with the 2A active balancers. Since I have 10 total banks in all and it spreads out the...

Which pin connector hole is the right one? 16s 2A balancer

Got an order for 64 of them from 18650 delivered today. Here is the packaging And of course punctured with a lift

Not sure where to mount these at. My packs are 3 wide and I have a strip of wood across the top with the bms mounted on em. Do these balancers get hot? Or potentially catch fire? Sage to put a piece of rubber on top of bms and then balancer on top of that? Or just run extra long wires to the...

Have 6 strings of 280AH. Over the last few months the capacity has been falling on 4 of them. Needs to be top balanced? Or something else going on? Using overkill BMS on em.

In the manual it says to use a 10awg ground wire to the inverter from grid input. Since I have 4 units and all would be connected to the same ground bar in the panel couldn't I just use 1 bigger wire? Say 1 6awg wire from subpanel to wiring trough, and have the inverters running a 10 awg to the...

I have 4 of the mpp pip5048mgx units I have hung up. I'm now trying to get them to power my house. Of course they are single phase units and I need split phase. I have a 37.5kw transformer that I use to get my 120v/120v from. When I just turn 1 unit on the transformer is buzzing and I'm getting...

I have 6 strings of 280AH batteries on a 48 volt system. Last weekend I installed my 4 mpp 5048MGX inverters and programmed them to charge the way that off grid solar recommended on his site. I tried looking at his bms settings and match them into the overkill but get confused on the language...

I'm trying to buy some end caps for the tubes and have no clue what they are. Their is no stamping on the tubes whatsoever of what I can see. I need to buy some caps because after a trip to the emergency room where multiple stitches were involved and several people banging their heads on it...

Got both my Android phone and IPad with the app downloaded. I think with Apple you have to pay to change settings but I can see all 6 BMS's that I have. With the Android I only see settings of I guess one of em. Not sure what all the settings do and read the manual but don't know how to...

Putting some strings together and found a cell with a bent post. Wasn't gonna use it and I had ordered another cell for a just in case purpose. Gonna switch em out and saw it also had a Bent post. It is the negative post and I put it on the very end where the bms hooks up to it. Figured it...

Out of 32 cells they all tested 3.28 but 1 cell that was 2.8. You think their is going to be any issues with the battery cell or just needs charging and then balancing?

Finally going to start charging up my cells. I"m going to first charge my top 3 banks up because I'm missing 3 cells on my bottom bank so I can't assemble them and wire it up yet. I have the 3 strings controlled by an overkill 16S bms and will be charging them with a couple of MPP solar Pip 5K...

Going to end up adding an additional 18kw of panels on a shop roof this will bring me to around 36kw of power on tap. Been looking at S5 and K2 brand of mounts. Not really understanding how S5 works without crushing the ribs in the tin virtually destroying the tin ribs if you ever remove the...

After watching various youtube videos of guys wiring their BMS on their 16S packs they usually have like 15 cables going to the positive side of the battery. According to the Overkill site approximately half the batteries receive the positive and the other half the negative...

Bought 4 of these units to replace my Revo II's. The communication and current sharing boards are not installed. Has anyone installed these and is their a video on it? Also has anyone got a video on the settings on these units? I'll be using LiFePO2, 4 strings of 280AH. I'm planning on just...

Do you have to use a relay with the chargery bms? If so what kind? I have 4 banks of batteries with a chargery 300 amp on each one. Where is the relay placed? Do I need 4 of these relays...

Been looking at buying 4- 5k hybrid inverters. Want these units to work with North American current where its basically a H-N-H for the input and output. Was referred to go with growatt. After talking to a salesman then a tech guy left me as confused as ever telling me that I need a split...

Having a unit that only has a neutral/ Hot/ Ground on input and output means no split phase 120v/120v but only 240 volt right? This is the unit in question. I am using 4 of them. http://www.sorotecups.com/product-detail/on-grid-off-grid-hybrid-inverter/ Voltage range on input is 120v-280v...

Saw this article on how lithium can last up to 2 million miles at being kept at 60 degrees Celsius or 140F. If it can be used that much longer in a car at that temp then it would last a great deal longer being used in off grid situations...

Order placed on Nov 8th through Michael B Caro and still waiting on em. I dont know whats going on but I wished they would get their butt in gear about it. Ordered my bms around a month ago and already out of customs and being shipped out via DHL. Last time I ordered cells by the time I...

I redid the way my solar installer had my system set up and now im tripping breakers and dont know why. I had one of my units go bad on me and couldnt replace it without removing the wires from the 2 units because they had the wires traveling through one another and had them pretty much anchored...

Ordered 5 hybrid inverter/ charge controllers from overseas. They were flown in and i got a call from a UPS agent wanting my SS#. Checked on my package and if it was sent out yet. Saw this mesaage on my tracking number. Cost including shipping was $4140 it was $3575 for the 5 units themselves...

So I guess my cells will be arriving here hopefully by the end of the week. I'm going to be running 3 strings of 16s. I know I need to balance them when they get here. I guess all that details is connecting them all together with all the positives and then all the negatives? After the cells...

have the current going through it from the charge controller. Can I just use a BMS that balances the cells and communicates with the charge controller through a RS232 comm port? Say the pack reaches 90% full and the BMS tells the controller that it is 90% full and the settings that is manually...

Recently purchased 48-280AH cells. Going to run them in a 48 volt system. I've emailed several BMS manufacturers and only a couple got back with me saying they do not make a BMS for a 48 volt system or I'd have to buy a certain battery they supply BMS for. I've asked several people including...

On Alibaba? Just had one company basically close a potential purchase on me because of shipping. Those were 48-340 watt panels from perlight solar. Wanting around 16k to go with the 12-335 panels i already have and have hybrid inverters thats able to supply current to my subpanel and charge...

I messaged a seller on Alibaba about purchasing 48-340 watt panels and i got this message in return. "Dear，can you accept FOB OR CIF terms?" Is she asking if i can drive to the port and pick up the panels myself? Not sure what she wants to know. I just got done purchasing 48 lithium cells...
