Cerbo GX and multiple battery banks
I have 10KW of 48v main batteries connected to my Cerbo GX via BMS-Can, with 2.6KW of 12v house batteries on a SmartShunt connected to the Cerbo GX via VE.Direct in my 5th Wheel RV. To add to this thread, we have three battery banks, 48V propulsion, 24V house and 12V gen set start battery. Appears that only one bank is visible on the "pages
Internal vs External BMS pros and cons
The external BMS/individual cell bank is used for high current demands taken by my inverter powering a microwave oven and induction stovetop, and also serves as a backup to the house bank through a steering diode. If a cell goes soft on that bank, I can replace that individual cell, and on a cost-per-watt-hour basis, the external BMS batteries
Battery bank wiring matters. It matters how a battery bank is wired into the system. When wiring a battery bank, it is easy to make a mistake. One of the most common mistakes is to parallel all the batteries together and then connect one side of the parallel battery bank to the electrical installation. As indicated in the image on the right.
What is BMS Battery Management System?
Battery management systems (BMS) and battery monitoring systems (BMoS) are designed for monitoring the battery status. However, BMS includes battery management, charging, and discharging operations, and usually contains more functions and modules, such as battery balancing and fault detection. Comparing BMS to Battery Energy Storage System (BESS)
Different sized battery banks on a single inverter
I have a question about battery banks with a 48v inverter. Let''s say i bought 16 of the 210ah lifepo4 and hooked them up with a bms to a 48v inverter. Let''s say in 6 months I buy 16 280ah lifepo4 batteries connect to a different bms but still tired to the same inverter. Basically 2
VE Lithium Battery Bank, Which BMS to Use?
I am in the middle of a similar design and like you I am struggling with the choice of BMS. The video referenced may help. As the video points out the BMS 12/200 can limit the current from the alternator ( a critical step to not burning out the alternator) but does so on the negative side.The disadvantage of the 12/200 and the CL 12/100 seems to be the inability to regulate
Parallel connection of two BMS for one battery.
Most situation won''t push the BMS close to their limits but if you''re using two BMS on one battery and push them to the limits. I can think of several ways that Parallel BMS for one battery "might" cause problems. Let''s say you have a 100 Amp charger and a 100 Amp load but each BMS can only handle 50 Amps Charge and 50 Amps draw.
build a battery bank with the potential to operate at an increased voltage, or with increased capacity and runtime, or both. To Series, Parallel, or Series and Parallel lithium batteries with a BMS you must first understand what a "true" BMS is, what it does, and what challenges the BMS in your battery may present to series, parallel, or

Parallel Battery String Topologies, solution needed for JK and other BMS
Definitely possible if you using fast-acting Class-T fuse and if properly sized you will not have issue with Parallel battery banks and inrush scenarios. Just use fast-acting Class-T fuses between each parallel battery bank connecting to the bust terminals in parallel for all banks. Fuse will take hit before bms is going to be fried.

Now I have a 280ah-48v battery bank, Daly 16s-250a BMS, about tired of messing with it & want something better. Planning for the future off-grid setup; (4) 280ah-48v battery banks. I''m looking at OverKill but not sure the 16s-100a BMS is big enough.
Can I hook battery banks of two different sizes in parallel?
Apologies for lack of detailed info. My set up is set A 16S 48V 100AH and set B 16S 48V 90AH. Wanted to connect them at 48V in parallel, with the hope that i can find BMS with master and slave so that the BMS will communicate to my inverter, to u derstand the status of the 2 packs/set., impact of continuous discharge and charge considering they are at diff. capacity.
