I live 8 months a year on a 50' sailboat with 1800w of solar, and a 13.5 kWh bank I made from bare cells. My BMS is an REC Active BMS controlling the whole charge system via a Victron Cerbo GX. It is performing absolutely fantastically when I live aboard. The problem is my "layup settings"...

Just finished with my upgrade. Went from 4 tired AGM 160ah batt to 1120 ah of EVE cells in a spring-compressed fixture. Battery: 16X EVE (amy) 280ah cells, separated by thin silcone sheets, fixtured with with hydro-cut aluminum end plates, threaded rod, and springs. BMS: REC Active BMS...

Thought someone might be interested... I installed a GX touch (cerbo) in my boat. I really like the system, but the viewing angle of the display is poor, and touching the screen was awkward with where I had it mounted. It looks washed out when looking from slightly above. I designed and 3d...

I'm planning on assembling a 4P4S battery bank. Hypothetically, if I used the layout in the attached diagram, and was pulling, say, 100 amps, how many amps would be flowing through each link? My instinct is that the serial links would have more amps flowing through them than the parallel links...

I'm sure everyone is tired of talking about cell compression. I know I'm tired of reading about it (I've read many posts on many threads about it). What I'm hoping to discuss in this thread is compression and bus bars, but only as it relates to the integrity of the terminals. I have 16 EVE...

I'm looking for a cheap and reliable way to switch low voltage, low amperage (12v, 1 amp at most). The use cases I'm imagining are more like 50 milliamps. Example usage: Use my BMS to trigger single LED indicator bulb and low amperage piezo alarm. Use my BMS to trigger short of two signal...

Hi, I'm installing a LiFePo4 system with an REC BMS. Im trying to figure out how to control the charger, a Mastervolt Mastercharge 12-100 100 amp. The charger I have works well, but it doesn't have BMS start and stop signaling, so the only way I can think of to turn it off and on is with an...

Hi! This forum has been a huge help, I really have learned a lot. I’m in the middle of planning a LiFePo4 upgrade for my 50’ boat. I’ve thought a lot about it, studied a lot, and I think I have a good idea of how to proceed with a 12V AGM —> 12V LiFePo4 upgrade. I still have a few details to...

Hello everyone! I'm a full-time cruiser with my family of 4 on our Hanse 505 sailboat. Our boat is currently in dry dock in Puerto Penasco, Mexico for hurricane season while we visit friends and relatives for a couple of months. Our boat has a tired 12v 640ah AGM battery bank and 750w of solar...
