    Ideas on How to Remove 25ah Lifepo4 Cell Terminal?

    I need to remove a Cell Terminal identical to this. Anyone know if they use 2 rivets or if they are screws/bolts with the heads removed or how they are physically attached? Any creative ideas on how to remove them? I had no idea where to post this but I thought this might be the best place...

    How to balance these cells.

    Hello, I bought 4 of these very cheap* "Elfhub" 12V 100ah LiFeP04 batteries for $480 CAD each delivered. The BMS is very basic (I googled the numbers and found nothing), no Bluetooth or monitoring of any kind. I opened the cases and installed pigtails on the BMS harness run through the outside...

    Blocking Diodes on each Panel in a Series String – Partial Shading

    Hello folks, I’m wondering if it is feasible (or stupid) to put blocking diodes (I have a bunch of 20A 50V) on each panel positive output in a series string if the panels experience partial (often one part panel at a time) shading due to neighboring trees? Currently, one array consists of 9 100W...

    Include Shunts and Fuses in Wire Lengths?

    Hello folks, I understand it’s important to make sure wire lengths are equal from the inverter to the battery main negative and battery main positive. Do we include the length of the shunt and fuses when measuring for total length of each wire? Also, is there any reason to fuse the series...

    Different wire lengths to Bus Bars.

    Good day folks! I'm wondering if having this setup will be a problem for my new batteries. I have 8 x 6v Deep Cycle 225Ah, 2 sets wired in series for 24V, the top battery bank will have ~ 2ft of 1 gauge (doubled) to the bus bar and the bottom bank will have ~ 3.5ft of 1 gauge (doubled), then ~10...

    Please check my math..

    Good day folks! I think my math is correct and I’m hoping this will work. I have 12 x 12V 100W Panels: Maximum Power (Pmax): 100W Maximum System Voltage: 700 DC Maximum Power Voltage (Vmp): 18V Open Circuit Voltage: 21.6V Maximum Power Current (Imp): 5.55A Short Circuit Current: 6.06A And a...

    BMS with multiple battery modules - How many and how to connect.

    Hello folks! First timer here. Just dabbling into Solar and thinking of building my own battery modules for a 24V (possibly future 48V) system. I currently have six "Series 31" Deep Cycle Marine 12V batteries wired in 2s3p to the inverter, charged by a 60amp MPPT Charge Controller and eight...
