Update on Sterling Power A2B (Alternator to Batter charger) vs. Sterling Power B2B (Battery to Battery charger). Which works better to use while charging LiFePO4 batteries from your high output alternator? Recently I was searching everywhere for an alternative to the Renogy DC to DC 60a charger...

I'm just bought the 4000w version of this SunGoldPower pure sine wave inverter charger and my installer is telling me I need to also add on a 50a power supply if I want to be able to plug my 2004 Lance 1161 truck camper into shore power or a remote generator power. Is my installer wrong as your...

Agreed

Thanks. I think when I work backward even this large setup will only run and air conditioner for 2 hrs and of course going way smaller makes A/C during the summer impossible unless I spend 2-3k to install the highest SEER rated minisplit on the market. 800ah / 26A = 30.7 hrs. There not enough...

Yeah, my plan has alway been to have a large enough system to run an air conditioner in my truck camper during the summer. I was even originally planning to swap out the Coleman 13,500 BTU roof air conditioner to swap in a mini split but since its an old used truck camper, I'm think to spend a...

Hey folks so I'm finally getting closer to install day for the electrical upgrade to my 2004 Lance 1161 Truck Camper. I've spent hours researching DC to DC chargers and Battery to Battery chargers and have decided all of the ones currently on the market are meant to protect low or medium output...

Today I called Renogy tech support directly to ask if 2 Renogy 60a DC to DC chargers can be combined to increase the amp to 120. Renogy tech support technician said "we do not recommend combining more than 1 Renogy DC to DC chargers in parallel as one device might detect the charge from the...

Not sure if this helps but someone here in another diysolarforum.com thread also mentioned someone from Renogy tech support said 2 of their DC to DC chargers could not be used together. Here is a screen shot.

I thought he pointed to one of the buttons on the device.

I think this Sterling YouTube video shows how adjust to get a few more amps than what the B2B is rated for.

Here is the link to the Victron webinar where they was discuss using an Alternator to charge Lithium.

Victron in one of their YouTube videos says that their Victron Buck Boost DC-DC Converter 25A / 50A / 100A can also be used to regulate the amps from your alternator charging your batteries. At 100amps at 12v I believe that would be the most amps possible from any of the DC to DC device.

Perhaps another column of this chart might answer if multiple devices can be combined in parallel to increase the amps per hour of charging. Sterling in their YouTube videos says "yes" you can combine their B2B chargers and the amps don't even need to match to increase the amp per hour charged...

I apologize. I meant LiFePO4. I'm just a big dummie. Sorry :LOL:?

CORRECTION: So although I did call DC Power, Inc the maker of my 370a high output alternator is it was okay to hookup 3 - 150ah LiFeON4 batteries without a DC to DC converter and I think they told me they were not worried about their alternator overheating, I guess I had also sent them and email...
