    Xantrex SW2012 Charger Programming

    Last night I charged the batteries. I set the absorb time to 4 hours so the charger wouldn't shutdown prematurely. I kept on eye on things when I enabled the charger. Bulk mode only lasted a minute or so, then it went into absorb. After about 2 hours at 50amps (this is the highest amperage I...

    Xantrex SW2012 Charger Programming

    Hello, I'm having trouble programming my Xantrex Freedom SW2012 charger for lithium batteries. It won't stay in bulk mode very long even though the battery voltage is well below my setpoint. It will then go into absorb mode for as long as I have the timer set for. I've read through the...

    DC to DC Converter? Need Clean 12.0v DC

    No, I have a 12v bank. I didn't know if that converter would work, that's why I was asking. I'd like something simple, plug and play. The power requirements according to the manual are 110-240 V AC, 50-60 Hz, 20 W. I'm not in the same location as the booster right now, so I can't tell you...

    DC to DC Converter? Need Clean 12.0v DC

    I need a source of clean 12.0v DC to power my cell phone booster from my 12v battery bank. The booster came with a 120v wall wart plug that has an output of 12v DC. Would a 24v to 12v converter do this? Nextrox DC/DC Converter Regulator 24V Step Down To 12V 20A 240W Low Voltage Transformer...

    Combination Inverter/Charger or Separate Units

    The Magnum and the Victron units look nice, they cost quite a bit more than the Xantrex though. Looks like with the Magnum if I want to customize I need to buy the 150$ controller?

    Combination Inverter/Charger or Separate Units

    Hello, Should I buy a combination inverter/charger or keep them separate? I want to be able to customize the battery charger voltage and be able to adjust the low voltage cut off on the inverter. I'd prefer the system to be simple. It will be used by multiple people. I'll be charging 2...

    Comparable to Xantrex Freedom XC 1000

    I'm looking really hard at the Xantrex Freedom XC 1000 watt inverter/charger for my cabin. Is there a comparable unit out there? I want adjustable low voltage cut off, and to be able to customize the charger voltages. I only need 1000 watts, and I would like to keep the system simple and...

    Lipo battery winter storage

    The Trojan Trillium data sheet says they're safe to store at -40. I know these aren't the batteries the op was asking about, but can there really be that much difference between LiFep04 cells? Maybe it's the BMS CPU that doesn't like the cold weather...

    Lipo battery winter storage

    I've done allot of research and for storage every lipo manufacturer or builder spec sheet says to keep the battery above freezing in storage. Maybe this is for liability so nobody accidentally charges the battery below freezing? In the few mdsd /sds I've found, there is no caution of keeping...

    Lipo battery winter storage

    I would dig a hole below the frost line, put the batteries in a box in the hole, and insulate it well. I'm looking at a battery from Expion360 and they're telling me it can safely be stored down to -40 at a 30-40% state of charge.
