I’m trying to figure out which would be a more efficient way to power an RV fridge. I currently have a small countertop 120v ac fridge for use thru an inverter. I’m am looking for the best method for efficiency. Is a 12v d/c refrigerator generally more efficient to operate than a 120v a/c unit?

Anyone know what size the bolts are for the 24v A123 battery terminals. Can’t find and specs on it and long drive to the hardware store out here with a 50lb battery. Called b battery they didn’t know... nothing on google.

Has anybody had any experience with returns from Ailiexpress? No having much luck with a Ruixu battery return. the message board for Rachel is not good. They say return to US address but give no address When I asked for the address the message back was I’ll tell you later. Red warning flags...

I’ve seen a few posts concerning using the load terminals on Charge controllers and see where some try to use them for loads too high causing problems. Some say not to use them at all. I use this feature only on low power outside led lighting and use the timer function to set on/off power to...

Has anyone ever tried to ship a lifepo battery within the US from one private party to another? After talking to UPS and Fedex it seems you have to be a licensed haz-mat shipper to do this. Or you must take it to a third party haz-mat shipper to ship which would cost even more than paying for...

I have a capacity test running on the tester in Wills video. Set it at only 130watts 11amps this time for a longer test and so there’s no smoke. ? Can I get some input on getting a full capacity test discharge down to a safe level on my 12v 100ah LiFePo Ruixu drop in With the new batteryhookup...

I know this has been brought up before but a couldn’t find the particular post. Most SCC charge the battery upto 14.4 before reverting to a float charge of maybe 13.5v. I know 13.6v is 100% SOC at Resting voltage. I’ve read not constantly charging to 14.4v will give a longer charge cycle life...

For you helpful electricians? Question on supplying AC to a single AC outlet. I am installing shore power into my cargo trailer project to a couple AC outlets via a two 15amp breaker panel one for each outlet. I also have a 1500w pure sine inverter on board. I would like to use one of the AC...

Good morning I got this notification this morning from Costco for today. Just a heads up. ? Sale is 12/12 - 12/14 May or may not be a deal for those looking for this type of ready built power w/ 200w PVs. But being sold by Costco customer service is a good thing.

Ok rookie totally in the dark here on proper settings. With the iOS Xiaoxiang app version has nothing written in settings and looking for some suggestions from those who can advise on correct settings 100ah 12v 4s redone Ruixu drop in with bhu smart BMS. Used in cargo trailer build. No big loads...

Not clear on balancing cells yet. On my Ruixu 100ah or other drop in LiFePo’s, will the BMS bottom balance the cells if drained down to 10.5v (MPP cut off)? Comes back up to 11.5v after sitting. Let it sit for a bit then charge back up? Is this necessary or not? Don't mean to sound dumb but...

My Drop in batteries BMS allowed my 12v LIFePo to disconnect at 8.6v. 2.15v Per cell. No expert but that represents an unhealthy and life shortening condition for a 12v LIFePo. Manufacturer is saying that's ok???? But lists their BMS LVD at 10.4v Especially if not recharged quickly. Opinions...

I'm looking at a Samlex 2000w 24v inverter model # PST-2000-24 . I cant seem to find info on whether these are high frequency or low frequency inverters. From reading I'm assuming LF is a better unit. Also any opinions on like Aims inverters would be helpful. Thanks

Do additional MC4 connecters add significant additional resistance to the cabling from panels to CC? I am asking because I am making 10’ extensions to my existing lines to position the panels in a more sunny area. (I thought about using heat shrink self sealing butt connecters as an...

Huh? who’s there????

Looking for advise on which would be a better option for a cargo trailer conversion I’m slowly building. the trailer is a 6’x10’ v nose so roof area is limited because of a roof vent in the center. The current plan was 3 100w panels in series—60v 5-6 amps into an MPPT for efficiency. They weigh...

What would be considered a safe time limit between the time your BMS shuts your LiFePo battery down with BMS set at 11.2v low volt disconnect at night after using to the time the sunrise begins recharging the battery back up? I know it’s not a wise practice and can damage a LiFePo sitting at...

Ok I’ve got this double load center box going in and the plan was two 15amp breakers going to two separate outlets. There’ll be one line in from the shore plug hot, neutral and ground. Two out. For two breakers there’s two hot lug connections on top. Neutral buss on right and a separate two...

After much back and forth with Ruixus Rachel with my fevered concerns on the infamous switcheroo of BMS type they asked if I would want to redo it myself with the correct BMS? And since shipping would be a long drawn out ordeal I agreed. I requested a new Ruixu battery case also as opening up...

Just curious if anyone else has ordered this battery 24v A123 LiFePo from Big Battery that was featured in Wills Youtube review this last weekend? And if you've received tracking info yet. Ordered mine on 7/11 so its been three business days and no tracking yet. Left an Email and a voice message...

Looking at the Victron smart solar 100/30 MPPT and like the compact sizing for building a 24v portable solar generator but Victron is pricy $$ compared to other quality larger sized MPPTs. I current have 2 EPever 4215bn MPPTs that have worked flawlessly for a couple years but they quite large...

Anybody else getting car sick? LOL

I’m trying to learn ALL useful parameter settings that could be best for LiFePo use and longevity of the expensive battery. I reading on some of the posts the float charge isn’t really needed for LiFePo batteries so on the MPPTs MT50 meter control parameter settings can it be set down to 0...

I just ordered this Massimo cx 50 from Costco 12/24v . I'm waiting for a spec sheet to be emailed to me currently. These are the same units as Alpicool just re branded. Price appears reasonable and they sell out fast. Wondering if anyone out there has experience with these and your results...

I just received my new delta 2 and 220w panel this weekend. I charged to 100% and did a discharge cycle test using a 1100w heat gun bring it down to 0% soc. This was less than the draw Will did on his review on YouTube video. And he had no trouble with recharging immediately after. @Will Prowse...

On a recent comparison video by Will seemed his only real concerns are with Smaller, weaker terminal connections (BB vs Lion energy) and vibration concerns on the terminals, I found these dense foam packing trays that came with a couple of LiFePo dropins i bought a while ago. Securely Mounting...

Ok electricians, Quick question on manual reset-able DC circuit breakers. There are two posts for connection, one is marked AUX and one is marked BAT. does it matter which post you connect each wire to? Are they one way? So basically can battery be connected to AUX post and power out be...

Just trying to find out if this is a normal thing. I have an Ecoflow D2 that allows 500w/60v max solar and has a 15a limit on the MPPT. I have three 195w Ecoworthy bifacial panels in parallel because series would be to much voltage. On a bright clear sunny day, panels at the correct angle to the...
