2021年1月10日 · Generally the recommended BMS for this configuration (recommended by Victron) is REC BMS. There are others that would work also (Batrium, Orion Jr) but REC is the standard IMHO. With REC (and the others), the BMS "talks" to the Victron system (inverters, charge controllers) and tells them how to charge and when to lower the charge current etc ...

2022年12月28日 · The terminology is 3P4S, which means 3 cells in parallel connected to another 3 cells in parallel and so on. There are five BMS wires as shown in your diagram. Consider each parallel group of three a single cell for the purposes of reconciling to the diagram.

2020年4月24日 · No, you can't use a 4s BMS for a 4s3p configuration. However, if it was 3p4s then you could use one BMS. It's not what I would do, but there are a few forum members doing it that way.

2022年12月3日 · Yes, that is 4S3P. However, that's bad: you won't find a BMS for it, and if any cell becomes weak, the entire battery will suffer. Instead, you need to make a 3P4S arrangement :

2010年9月23日 · Maybe a 4s3p type pack that would be "charged" by the dc/dc converter. Would this need a shunting bms, or simple voltage monitoring or nothing at all? I will be building my own bms for the main pack that measures the voltage of each cell in real time and show me the high cell, low cell and average of all the cells.

2023年10月31日 · Looking for a 4s3p bms using 3v lithium cr123a batteries. I'm working on making lights for at night with my skateboard and landed on using 15v rv leds. Next the battery powering it all, I already had a bunch of lithium cr123as that …

Today I’m Gonna show how I build this 12V 4S3P LiFePo4 Battery Pack With BMS and Balance Charging. Click Here to See The Video. Let's Start

Lifepo4 32700 21Ah 12.8v 4S3P Battery Pack with 40A Balanced BMS for Electric Boat and Uninterrupted Power Supply

You've made a functional and reliable lithium ion battery similar to a 4S 5000 mAh LiPo pack for a fraction of the cost! Yes, you need a charger, but if you have an old laptop battery lying around, some wire, charging plug, and solder tabs, then all you need is the BMS to get going which costs around $10 USD or less if you buy it from China.

I want to build a bank around 10kWh capacity, and each VW module inside the VW battery is 4S3P, based on Samsung 37aH cells. I need 6 modules to reach the wanted capacity. So far so good, but I fear I have an issue with battery bank composition and my expected result.
