275943225177 I’m level 40... lotsa walking.

Just an FYI, i noticed relion batteries at bass pro. They had 50, 80 and a few different 100Ah types built by relion. Pricy, but on the shelf... may be worth it to some in a pinch. They even had the starting version on the shelf.

really... first the video on his new car purchase... Next the 48V system video goes down... ugh. his videos are for learning... complaints SUCK!

The video came off as a paid commercial more than a review of the tracker… he showed over 400W output from his 400W array… kinda dubious there… I will try and find the video.

Any chance a bilingual member can suggest a solution to the language barrier to fix the forum?

This just popped up in my feed, and I like the made in USA solar panels... cute ad also...

They have a sticker on the back showing voltage and wattage... Also a warning not to put them in series. Why? I know little about solar panel wiring, and wonder what makes them suitable only for parallel... My guess is to limit use to simple battery charging with their pwm controller...

Ok, I have been looking for a cheap EV for my wife… she drives an 01 Passat now, and I’ve spent innumerable amounts on service of the car… also, it has an oil leak, goes through about a quart a month, and it stinks… the shop is pricy to get it fixed up… And of course fuel. She doesn’t drive...

I guess it is a MASSIVE inductor... Only two wires on it. Winding appears to be solid #6 varnished flat conductor. Wood core, iron cage. Weighs about 40Lbs...

I started playing with 180W solar on my patio, but it is only 12V (22VOC, 17VMPPT) SO, I tied it to a 100Ah AGM, and hooked up my buck/boost set to 27.2 CV and 1.0A CC and I am trickle charging my 24V lifepo4 sets for experiments... Seems to work nicely... I will bump up to 28.8 gradually...

https://www.amazon.com/gp/product/B07SWVPXWM/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 Anybody have any experience with it? Seems pretty decent. Nice display, auto battery voltage detect, handles 150V when charging 48v. Oddly, it only handles 100V when charging 24v, and 80V I think when...

I have a few that have failed. A generic 30amp model, an aims 60A model, both just stopped registering solar input. And a 30A make sky blue that got exposed to rain and now does nothing.

I took the family out to a nice dinner, and on the way home she insists at 10:00 PM that we need to go to the grocery store for a few things... I relent, and go... she goes in the store while I use my phone to check a few things... A few minutes later, she comes back to the car frantic cause...

I have a generic OVERKILL style JBD BMS. it never charges evenly, pack 4 always hits 3.6 before the others get out of 3.3… so I decided to hook a 5a CV charger to the low cells. sounded simple, however, I hit an issue. Cell 2 charges fine up to 3.6, cell 1 fine up to 3.6 cell 3… when charging...

Lead acid is of course what it came with, and would offer the most versatility weather wise. But he will have two 60A 24V charge controllers on it, so I calculate average 14KWh solar charging... figure setup 5KW panels so max input throughout the day... but, 30KWh of lead minimum has charging...

I have a hoverboard battery, it specs as 25.2V... It has18650 cells in a 7s arrangement, making me think they are lfp cells, but the number on the cells leads me to think LiNNMC ... Sooo... Is the voltage wrong, or is the cell labeled wrong? The HCYINR18650 part googles to a LiNNMC chemistry...
