This is the timeline I recorded when top balance my EVE 280AH cells I purchased from @Amy Wan (Luyuan) at Shenzhen Luyuan.
Tools:
Cheap 10A - 30V Power Supply (w/new 10 gauge leads and larger clips)
Two tested multimeters - to confirm accuracy
Patience
Timeline:
Paralleled cells and set PS...
An update on my helicoil adventures: I got in on a Michael B. Caro battery group buy a while back, and the 4 - 280AH cells arrived dented, etc. To his credit, at that time Michael was prompt in contacting the supplier and ultimately giving me a full refund. At that time the cells were tapped for...
Hi all - just a heads up if you have this charge controller: apparently, by default from the factory, this controller comes with the entrance/exit cable screw terminal clamp/jaws (2 jaws in each cable entrance - top & bottom) 'closed' and they must be 'opened' before inserting the cables -...
I ran across this review for the Montek X-1000 (rated at 1010wh) and in it the reviewer explains that it's not the stated battery capacity (1010 watt hours in this case) but rather the efficiency (~ 90% in this case) of the unit that determines its value. So as consumers we shouldn't expect a...
I finally received my first AliExpress purchase: a HIDANCE DT3010 DC Battery Capacity DC Power meter. What I received doesn't quite look like the first pictures in the advertisement, nor does it correspond with the ones I've seen Will use in some of his videos.
In short, the meter I received...
I've had one order for 280Ah cells on AliExpress which I was refunded for after non-receipt, and one order pending receipt from Alibaba. In both cases I've been charged a separate "transaction service fee" by the website (not the vendor) of around 3% which was added after the fact to the credit...
My pre-Lifepo4 small camp trailer build initially started with 1 - 100W Renogy panel, 1 - 30A Renogy PWM SCC, a 1000W ECOA inverter, and a 100AH SLA battery. I installed a WFCO WF-8955 55A power center to handle shore power charging and to provide a fused DC side for connecting the 12V side to...
Hello - looking for anyone with experience with either an all-in-one (panels, batteries, etc) or install-only solar installation company in the western US (Northern California, Southern Oregon, or western Nevada, most likely).
I've contacted Steve from Overkill several times on this and haven't heard back. Perhaps others here can shed some light on what's going on. The discussion thus far:
"Hi Steve - I have two of the JBD Overkill BMS's for two separate 4S 280AH battery packs. One I've used throughout the year in a...
Hi folks - I submitted a trouble ticket to Renogy, and the reply seems nonsensical to me, but what do I know? The gist is below - any suggestions are welcome.
Me:
"My new Renogy Wanderer PWM seems to exceed 15 Volts intermittently which (I think) causes inverter to shutdown due to over-voltage...
The menagerie foreign of foreign battery suppliers (if I calculated correctly) can deliver a 100 - 280 AH LiFePO4 battery (sans controller or other needed parts) for between $1.90's to $2.25 per amp hour, all day long. Does this sound about right?
