    How to monitor SOK battery or skip them altogether...?

    Thanks for the info, I am planning on using a shunt. Was not sure the BMS/dongle would support multiple bluetooth addresses identifiers.

    JBD / Overkill BMS 120A 4S Lifepo4 in series / parallel

    I looked at the Overkills pdf on the JBD BMS, and they state on page 30 it is o.k. to use in series. vague on what the max number in series. That is number of individual 12dc xxxah each with own BMS in series. How do you monitor a 24vdc pack? With each 12vdc pack own BMS via Bluetooth? Is...

    How to monitor SOK battery or skip them altogether...?

    I have received my two JBD 12vdc 120 ah BMS with the bluetooth adapter. I have not yet received my 8 105ah Lifepo4 batteries, on slow boat from china. I am going to build two 12vdc 105ah with JBD BMS with bluetooth. My question, with two complete batteries, and placing them in series for a 24...

    How to monitor SOK battery or skip them altogether...?

    I was in the same position, which BMS...apparently Overkill's is almost identical to the JBD. I ended up getting the JBD direct from the factory, I am building a 105ah Lithium Iron 24vdc system with the JBD bms. I also think you can get the JBD with bluetooth from batteryhookup. I got the...

Also once the pin (Female connecting plane, Male connecting plate) in above drawing is installed. It is not reversible and they are designed not...

    How to monitor SOK battery or skip them altogether...?

    Considering your background, why not build your own battery? Lots of DIY info here. Downside, getting the LifePo4 you desire may be an issue, but if you look on the forum, you will find a Texas supplier that ships and has good prices. Cells, BMS, some wire, lugs you are in business.

    Our NEW GO-TO LiFePO4 vendor...09.20.21

    I have a order in also with Amy Wan at Luyuan for 8 cells 105ah, ordered on 9/7/2021 with a guesstimate of arrival 50-60 days with a supplied tracking number.

    Epever Tracer 4215bn controller recommended settings

    Mike: Very helpful and thanks. I am due to receive the 2215bn (Oct 2) tomorrow and was wondering about the user profile settings. Once it is set up and data is saved. If the PV panels and the battery are disconnected (solar generator emergency use), does the unit retain your user settings in...

    Epever Tracer 4215bn controller recommended settings

    I am considering purchasing the EpEver 2215bn. Does anyone have a specific set-up to be used with the LiFepo4 105ah in a 24vdc battery setup. Or a link that has all of the required recommended starting settings? I do understand that you provide in inputs via the MT-50, plus I have read that...

    Yes 12vdc battery in series would work .

    my updated system diagram. submitted for your approval.

    This is a massive amount of current to use. A slightly loose connection in that high current application, caused by vibrations going down the road, could lead to a very quick disaster. Have you considered a series configuration, such as 24vdc, then get a 24vdc to 12vdc converter for you 12 v...

    Shenzhen Basen vs Shenzen Luyuan Lifepo4?

    Thanks, I just looked at the JBD Ali express offerings, and the Overkill offering. Does the JBD work with Android APK? I looked at the link of the Ali express, unfortunately it was Chinese language. Also downloaded the Overkill JBD/users manual, the link for the android APK in the manual from...

    Shenzhen Basen vs Shenzen Luyuan Lifepo4?

    Thanks I just received a quote from AMY and will be placing order soon. I will also order the 8 of the 105ah. What BMS have you elected to use with these units? My current thought is to go in series for a 24vdc setup at 105ah. Or could parallel for 210ah at 12vdc. This is to be used as a...
