Thanks Murphy, I'll try topping it off and see how it works out. I suspect if it continues to drain faster, might be a bad connection somewhere.

Hello, I have a Batrium 14S Watchmon with Longmons. The first cell is always lower than the rest of the pack. Even after top balancing, it depletes the fastest. Is this because it's the last pack in the series that goes to negative side of shunt?

I'll check on the ohms, but it is a new pack and is always that last cell. I'm running Batrium Watchmon 4 w/Longmons. I think bus bars may be in order.

I checked all connections and they are tight/secure. Any time I switch the inverter to charge, the last pack in the series always immediately charges with more volts than the rest of the packs.

Hi, I'm having a recurring issue with my 48v 550ah 14S (NMC) battery bank. I have a Batrium Watchmon 4 BMS with Longmons and the last cell (1st cell according to Batrium), the one that connects to the negative side of the Batrium shunt, always runs out of balance (higher voltage than other...

How are the battery packs working out for you?

I just noticed the DCC has a 12V driving voltage. Do I need to get a step-down converter since I am running 48V pack?

Would you guys recommend I get 3 separate 24S BMS's to monitor each pack in an attempt to bleed off higher voltage packs individually? Maybe even a Batrium with 70 longmons?

Sorry, I meant 14 packs in series (50V) and then put in parallel vs. the 5 packs I have in parallel which were then put in series. Chargery shows 4.3V and multimeter shows 4.1V. There are no wiring issues.

Hello, I have 70 packs of NMC. Each pack contains 40 18650 batteries and is rated 3.6V and 110ah. I currently have 5 of these packs connected in parallel, which were then connected in series to make 5P14S. For the sake of overall efficiency/charging including a BMS, is it better to have...

Wow Steve, thanks! I believe you hit the nail on the head with that one. Yes, I have been customizing the parameters of the Chargery for my needs and I'm not quite sure if this setup is optimized for my use- even with the DCC. As it sits right now, I have 5 packs in parallel and then in...

My listed voltages are based off multimeter. Chargery is seeing about a +200mv difference from multimeter. All of my wiring is fine. Just trying to figure out why some are showing 4.1V and other packs are 3.6V.

The packs I use are rated at 110ah and contained (40) NMC's that individually have a 10A discharge rating. I have my Sol-Ark charge/discharge at 100A, as well as my Chargery 16T. And yes, I did top balance prior to putting into service. 10A x 14S= 140A- so I believe 100A charge/discharge...

Hey Everyone, I have a 14S battery pack that consists of 5 cells in parallel (5P) that's connected to another 5P in series that looks like this: -----/+++++/-----/+++++ The problem I am having is that at the series connection, + from one cell to the - of another cell is not balancing. I am...

Got my 300A DCC connected and noticed the following: The screen on the 16T BMS turns on and off and I get 3 rapid flashes, followed by 3 more rapid flashes when the DCC "status" lights go on/off. From my understanding, this is when the relay opens/closes. Also, when the relay is going...

Does anyone have any updates on the new DCC? I ordered one last week but shipment was held off as the DCC needed to be tested and fixed per Jason. Looking forward to it's simplicity and capabilities.

I have a Sol-Ark 12k inverter and 48V 550ah battery 18650 battery bank. The inverter has battery settings for Max Amp Charge/ Discharge. Most will put 1/4 of the battery packs 'ah' for charge/ discharge, so I could roughly put 120A charge/discharge. But, since my inverter is connected to a 50A...

I have a 260VDC battery bank with CAN hi/low and am curious if this unit will work for me? What happens if you don't meet the nominal Voltage the inverter specifies? Will it not register/be recognized by the inverter?

Did you ever get this inverter to work with your system?

I have an 86VDC Tabuchi battery pack (24s 3.6V) that has 2 wire CAN with the BMS. I'm wondering if the BMS will still function if I hook it up to a charger/Inverter without the CAN wires attached as I can't locate a Tabuchi inverter? If not, I am thinking about breaking apart the battery pack...

Those were my thoughts. That's why I'm thinking just maybe use without BMS or using electrodacus or the like.

MisterSandals, I've read that inverters need to talk the same dialect based on their CAN coding which would be why Solax is saying that? What are your thoughts, should I try using the Solax inverter as the charging specs are nearly identical to the Tabuchi inverter? Or do inverters need to...

So my plan was to use this battery pack to use with a Fronius or Solax A1-ESS, but after speaking to the retailer (Bluesun) of Solax, they said the inverters will only work with Solax batteries. Since I cannot find an inverter that will work with my Tabuchi batteries, should I just take them...

Does anyone know of any hybrid all-in-one (non-24/48V DC) inverters that will work with 90-260V DC battery banks? The only ones that will accept the high battery voltage are from Asia (Growatt/Solax) but are 230V/400V DC output for grid tie. The SolarCity Delta H6 6000 inverter might work but...

Thanks everyone. The manuals are pretty useless and only shows one wire coming from the inverter which indicates "STORAGE BATTERY SIGNAL." The single wire coming from the storage battery signal eventually splits into two where it plugs into the battery pack. This being an 86V battery (10kwh)...

What could this possibly be for, and would it be needed for charging?

Hello everyone, I recently bought a Tabuchi 10kwh battery bank and it has these 2 connections left of the battery terminals (see photo). I don't know what they're for but the manual says communication cables from the Tabuchi inverter attaches to it. I am not using the Tabuchi inverter. I...
