So how do you measure the clamping force applied? To work out the stud torque.

I've read some of this topic thread, can people confirm to me what the recommended clamping force should be for a 280ah cell in Nm & do you multiply this by 4 cells for a 12v battery pack? Nm being applied with a small 'bicycle tool' 1/4" drive torque wrench, clamped between 2 suitable metal...

I've seen other users that have shown bigger dents than that and they have continued to use the cell with no detrimental effects. Caution is good, but I think these LFP cells are pretty forgiving?

Another saying "Never argue with an idiot, they will take you down to their level, and beat you with experience"

From what pictures I've seen, the BT280 has slightly smaller terminal areas than their REPT brother & the QR codes are in different locations.

YouTuber by the name of Brad, I believe is also a member on here also tested these Wending cells. Maybe he can help reply as well as Ave Joe?

Hi, i've just got an EBC-A20 without the Blue USB Cable included. Will a PL2303TA cable be compatible with this tester? (I have 3) I've tried linking to your pcb connections,as shown above, but no comms or PC showing in the tester window for me? Running the software on a Win7 Laptop, using...

Part of the REPT group of companies. REPT cells seem to have good feedback from what I've found. I like the square stud area for larger busbar contact. I have some on order.

Lowest power 240v microwave I've found is a Daewoo Qt 14L 600w output, draws 1000w which is about 95/100A from a 120ah 12v LFP into a PSW Reliable brand inverter. Works a treat ☺️ (Also branded as other makes)

Any update? Any internal photo's & info of the parts? Any capacity tests? Thanks

I didn't find out the BMS supplier Keith, but if u look at my first photo it shows a small heat shrinked BT interface under the false lid skin. Tbh your better off using your Ali battery monitor..... More accurate & quicker than any App BMS malarkey M8. Maybe your 12.2v reading was the shelf...

How did u get the top off? It beat me! Did u find the BMS model info?

The frog, I suggest you research the correct way to capacity test a LFP battery before posting 'Inaccurate results' Post some photos of the insides for potential buyers to view please ☺

Why are you concerned about the low temp sensor if you have a Victron Charge Controller?

Rocksnsalt Why do you need an app to use a battery? Does your sprinter have an app for you to look and see its current 'fuel' level? .... Hell, it's got a miracle thing called a 'gauge!' Just get a battery monitor & shunt, then you can see accurate Ah's remaining in a second, before you've...

Just buy a decent charger SCC that controls the charging in low temperatures, problem solved!

Have you checked the cell balance? Maybe balance charge it with a hobby charger?

Find it on apkcombo.com. worked for me (y)

Yes the DC home works ok (my android version was the issue?) What info on your faulty battery does the app show? What have Renogy said to you about warranty? (My battery was purchased as faulty, buyer was refunded for the faulty purchase, I like to fix things :) ) To activate a battery in...

Correct, I didn't open the lid further as I found the issue. Unable to see the cell terminals that can identify the brand, as the busbars are welded over them. The BMS looks a decent size & is red like in the advert pictures (tho on the opposite side in reality)

Steel ruler and Stanley knife repetition until it finally worked through about 2.5/3mm? Lid & the support 10mm braces. It was pretty tough going, but enabled me to find & rectify the fault. I was also able to manually probe into the cell packs and manually top balance them (over 250mv DV from...

:oops: Gloves? Etc. Nice sparking at the end :)

I think you will find the 150ah spec test is on a 0.2c discharge test (yours is 0.1c). The Wh spec is rated @ nominal voltage of 12.8v, so 150x12.8= 1920Wh These may have affected your results? Also remember most reputable spec batteries usually test +5% ish higher when new, + your discharge...

Another (y) for Renogy here. Whilst the after sales support can be a bit slow, it does work and they honour their warranty. Will's review of the 100ah was 5*. The internals of my 200ah LFP look really good too!

Fault fixed! (y):giggle: Turned out to be a broken balance lead connection, BMS wasn't happy, so did it's job & refused to work! All as designed. The internals of this battery are pretty impressive! All nicely laid out. Large welded Ali busbars across each 4 x50ah cell pack (16cells). Looks...

Baked the black plastic case in the Sun & used a putty knife & old cutlery knives. Didn't budge! :( Renogy did too good a job with the glue on this one!

What's the best way & tools? For non destructive opening!! Sorry Will :) Heat/chill .......Putty knife/plastic trim tools? Etc Thanks

Fully charge both batteries & then link in parallel. Andy on the off grid garage did a YT about this,

I got the DC Home app working and the BT communicates but only if I bridge the mystery connector with a SCC temperature NTC sensor across it (about 11k ohm). The BMS is falsely reporting 2 cell voltages way off from my measured readings. 0.1v -4.9v randomly jumping about! What BMS brand do...

I managed to download the DC home app from apkcombo.com & got it working, if others have issues from the play store?

Put 24v input to a 12v device and the 'magic smoke' will run out of it ..... Just the once!

My recent new 200ah battery has the QR code for the DC Home App, I tried the old BT app, it connects, but it doesn't recognize the battery data.

This battery is either in shelf mode & won't accept a charge, or maybe there is a switch or temperature sensor missing ..... So the BMS says "NO!" I can't get the DC home app to work (separate issue & thread started!) I removed the false top cover lid from this battery case to reveal 6 small...

Hi folks, I'm loosing the will to live :-( ..... Just trying to install the Renogy DC Home app on any of 4 different android devices 4.4 to 9.0 and the play store just says 'not compatible with your device'. I've checked that the location GPS is on. When I search in the android store, I can't...

I thought the SOK batteries are metal case with screws holding the lid on? Will did a review strip down on the 100ah version. Website sales info states "Detachable Cover,Replaceable BMS or Cells" ...... So Easy! :-)
