    Am I crazy or does this work?/help me make it work

    Thank you for all of your constructive criticism ! Much appreciated, diminishing returns for sure. Conceptually the idea for the split pack came from essentially an hourglass with holes in it (losses) and each time the sand (energy) travels from one side(one part of battery) to the other, most...

    Am I crazy or does this work?/help me make it work

    so what should I do then? Are there any positive things to say? It is one single battery pack that would be split electronically. The generator activates once the battery drained to a certain percentage hence SPLIT - I`m aware of the laws of thermodynamics. *Would having the generator on at...

    Am I crazy or does this work?/help me make it work

    It is one battery pack that activates the generator once drained to a certain percentage hence SPLIT - I`m aware of the laws of thermodynamics. Would having the generator on at all times be any better or worse? Disregarding the split pack idea and addressing some of the others such as the copper...

    Am I crazy or does this work?/help me make it work

    I have a idea and wanted to know if any one thinks this is possible/worth. A HIGH EFFICIENCY MOTOR/DYNAMO GENERATOR to capacitor/s coupled with a SPLIT battery pack. however you split it (60-40, 70-30)(not a absolute but wouldn't it be hard to discharge and charge a battery at the same...

    Battery Failure

    That's what I was thinking. Not enough sun? Or maybe the charge parameters? I will look into this first, thank you!

    Battery Failure

    Hi Y'all! I recently put this battery together with a bms. After leaving it connected to my solar setup (campervan) for a few weeks it has sadly lowered voltage to 10.6 Any ideas as to what could of caused it. :shock:

    Building a 12v Van Battery

    HI! I'm back with another silly question haha I have connected the Cells in parallel and series, just like the image but I'm unsure about where to place the balance leads. There are 5 lines (1 black, 4 white)

    Building a 12v Van Battery

    Hi All! I am currently building a battery bank for my campervan, I am working with Lithium cells that are rated at 3.2v 100 AH I am joining these cells in parallel and then in series for a total of 8 cells at 12v 200 AH - also adding a BMS :D (replace the tape with copper plates) My question...

    Cycle Analyst V2.4 w/Shunt Confusion

    Hi! I have a Cycle Analyst v 2.4 I believe I'm at the last stage of hooking up my shunt to the controller, the shunt I am using has three additional wires (green, yellow, black) though that's what I am confused about. Do I need to use these and how would I connect them? also is there an easy...

    Solar power for Campervan

    I'm terrified of electricity and Im trying to tackle this alone rn and not having the best success/confidence. Would love some feedback or tips on how to set up two 275w panels to an Outback charge controller. I also have two Lithium Iron Phosphate batteries rated at 12.8v 38.4 Ahr (491.52 Whr)...

    Homemade Battery Build question??

    I built a 52v battery (58.8) 14s 10p without a BMS and used it once. After discharging it using my E-Bike the voltage in one of the cell groups dropped to 0.39. Is this a result a of a bad cell in the group or do I need a BMS or could it be an issue with how I wired the pack initially. Any...

    Need help with battery build/balance charge

    I replaced the power supply with a laptop charger that is the proper rating for the balance charger. It is charging and discharging the pack but I am having difficulty actually balancing it. The Cell voltages read 1) 3.5 2) 3.6 3) 3.6 4) 3.9 5) 3.8 6) 4.0 The balance charge doesn't seem...

    Need help with battery build/balance charge

    I am in the process of building a 58.8V 14s 10p triangle battery pack (mechanically split 8s 10p,6s 10p) I am stuck on balance charging. I have soldered the balance leads correctly but when I hook up the balance charger it reads:
