The 300 ah battery with BMS, etc is This includes shipping to my door.

I've looked at videos saying both approaches work to charge a Goal Zero 1500x using the alternator. The camper has a 190 watt solar panel, but I want the addition of alternator charging. The GZ has an upper charging limit of 50 volts, 50 amps, and 600 watts. It looks like the advantage of...

Someone from another forum just posted this. ________________________________________ if this works, you are effectively. proving the yeti link in vehicle mode is pointless. From what I see online, a minimum of 15v input is necessary to the MPPT controller of the Yeti. I'm not sure...

I'm not schooled enough to address your well-made points. I think I'll test the system to see if it works. The worst case scenario, which isn't bad actually, is just to put one wire to the GZ and one wire to the new battery from the output terminal on the Renogy with switches on both lines...

I certainly don't intend to use the output ports on the GZ to do anything other than to run accessories. Charging using the alternator to renogy mppt uses a 4 AWG cable and can be up to 50 amps. The cigarette plug is not used. Using the REnogy MPPT has been demonstrated to work charging a...

I put out a Request for Quote on Ali Baba to see what came up. This is the first response. It is about the same price as I got from Wistek, which no one here said they've dealt with. Just reaching out for your experiences... Jeff... Dear Jeffrey, Thanks for your quick reply. Ship to...

upstream battery details

I've considered that, and may do it. The camper is new and I'm going to give the GZ a chance. I'll test drive the scotched together system first...

Can I connect a 100ah LiFePo4 battery to the Goal Zero Yeti 1500x in parallel without needing anything but a fuse/cb between the two? I'm looking to double my battery capacity without getting rid of the GZ that came with my Scout camper. The GZ can handle 680 watts or 12 v and 50 amps input. I...

That's a good idea. That may end up being the best solution!!!

There is an excellent video that demonstrates how the Renogy unit can connect two LiFePo4 batteries, or an AGM for that matter. What I want to do is put the GZ downstream of the new camper battery. I'm hoping that by plugging the new LiFePO4 battery into the GZ high input port (12-50 volt...

Yes, for a couple hours. The only info I've found suggested using car chargers which are limited to 120 watts input. The GZ is capable of 600 watts, or 50 amps at 12 volts of input. Here's a graphic of what I'd like to do (without the solar panels for now). Do I need something to control...

I ran searches for Wistek and nothing came up. Does anyone have experience with this Chinese company? They sell https://wis-tek.com/products/wistek-lifepo4-battery-pack-48v-300ah-15kwh-solar-battery and https://wis-tek.com/products/wistek-ev-m30?variant=48343316758806 Both include...

Shipping is included in the price. That's why I'm asking if the company is legitimate - do they use grade A EVE cells and a decent BMS, software, etc.

I've been talking over whatsapp with "Mia" from Wis-tek. She quoted $2665.92 for 32 EVE MB31 cells. This is the best price I've run across. Again, has anyone done business with this company?
