    Any server rack batteries using a BMS with bluetooth function?

    Looking for this convenient feature. It's on my 2 diy setups and it's very convenient. Was hoping to find a rack mounted battery that had this feature. Any help would be appreciated.

    I just bought a JBD 250A BMS, model SP22S001 20S 250A, Will use it in a 16S configuration with 280ah cells. As usual, the manual is 'difficult' to work with. Question is: I can not find any information about this unit posted by members and would like to get some feedback if anyone has used it...

    Are there any decent lower cost controller alternatives than Victron?

    I have a need for an MPPT charge controller that will handle over 100v with 40 amp output. 48v lifep04 batteries. Victron recommends the 150/45 controller. Does anyone know of any decent lower cost alternatives? Thanks in advance... Update: November 2022 I bought a used 250v Midnite Solar...

    Riding Mower Batteries

    Suggestion: Will, how about doing reviews on riding mower batteries design, capacity, and ability to 'service' by the DIY folks. Something different? Lots of new equipment coming out and batteries are a major cost component. Thanks

    Magnum Energy MS4448PAE LiFePO4 Charger Settings:

    My ME-ARC remote control is version 3..01. I talked to Magnum support about upgrading to a Lithium profile since I'm about ready to replace the batteries with 280ah EVE cells. They did not suggest an upgrade to the remote control. However they did recommend charger settings for the LiFePO4...

    Victron Multiplus 48/3000

    I am very interested in getting one of these units but there is one item on the datasheet that concerns me. The input frequency can be 45-65Hz, which is ok. However the output frequency at 230v is listed as 50Hz, not the usual 60Hz needed in US. I did not see a multiplus with a 60Hz output...

    LiFePO4 internal resistance question

    I have 4 cells: The IR readings using the 5 in 1 cell meter that Will used in one of his videos are: 010,002,002,007. My question is: Based on these readings are these 'normal' or are there any areas of concern that I need to watch? Did some research but could not find information or I just...

    Battery Bolt Sizes

    I understand this is below even a basic question, however, I just got my brick batteries and they have terminal 'holes' in them that are larger than a US half inch. Went to Home Depot and they did not have metric large enough to verify the size and thread. I'm thinking they are size 14 with a...
