Jan 31, 2024 · I chose an Overkill bms (a JBD one). It fit the needs just fine. But my RV house battery, I needed large discharge amp throughput, (100a x2 was not big enough & that was the largest FET based bms available at the time), and communications, were the defining characteristics. I choose a Batrium bms.

Nov 26, 2019 · A health indicator for when/if the BMS dies. 10. Heartbeat monitor on BMS. Low voltage cutoff; That is part of 7. Load shedding. My idea is you start shedding non essential loads first and never get to the total low voltage cutoff. I want the BMS to stay running so when the sun comes up, the system will reboot itself.

Jul 22, 2023 · These BMS units are brand new and work for all variations from 7s to 21s and everything in between. This BMS is rated for 300a continuous. These come with the bluetooth already installed. Included is 4x 4AWG wires with ring terminals already crimped. This makes installation even easier for you...

Nov 12, 2020 · Rather than shell out another $250 for a replacement TinyBMS (which may not behave any better than the last one), I'm considering a different option. After reading through a few of the 'full' DIY BMS threads, I'm confident that option is way beyond my skill/knowledge level. I do love the idea of controlling things with a ESP32-based MCU (or ...

Sep 15, 2021 · Chinese BMS's typically figure about 20 watts of heating, but they don't take that for very long, a few minutes, before they get too hot and BMS shuts down from overheating. Besides a feeble aluminum cover plate for heat sinking, many BMS's mount the MOSFET's so the heat extraction is primarily from plastic side of MOSFET's with a sponge heat ...

May 10, 2021 · Newbie here and need some help choosing a bms and determining if there are any other components needed. Currently I am awaiting 12 Eve 280AH (3.2) Grade A cells which should be arriving in the next 2-4 weeks. I am planning to configure them in a 3P4S configuration and I am trying to determine...

Jan 30, 2020 · The BMS will use a true disconnect which will interrupt the current in both directions unlike half of the BMS on the market who just use mosfets in the simplest configuration for the disconnect (so the mosfets' body diodes still allow current to pass in the charge direction even when the mosfets are off, not really a good thing in an over ...

May 1, 2021 · Hello guys, I am planing a HV storage system with around 80-120S configuration. The motivation to move to higher voltage than 48V is pure C-rate driven => optimize lifetime and overall efficiency. But of course the BMS selection at this configuration is quite rare. can someone recommend any...

Sep 12, 2021 · I know nothing about that BMS. So I can't really comment. On balancing: I'm a BIG fan of Active balancing.I have worked with both the QNBBM 8S active balancer (which I think was about $150 from Aliexpress) and the Heltec capacitor 8S …
