Renogy panels, at least the old ones, are pretty robust.
What’s up with people here having mc4 connectors “crumbling”? (Second thread in a few days mentioning that) I have Renogy panels that are over 15 years old and some that are a year old, and never had a connector break in half, let alone “crumble”. I can’t speak for their batteries, but I have had zero issues with their panels or charge controllers. <shrug>
Would you consider opening it up, even if you had to physically cut it, and balancing the cells? At some point after days of dealing with something, no longer worth my time, they win.
FWIW, I bought some individual 50 ah cells and case and busbars and BMS to build my own, and there was very little cost difference for what I see in the US for the Renogy 50 ah battery and the from China cells, case, BMS, etc. I do know the quality I'm getting from a reputable Chinese dealer.
Why 7 days?WELL GUESS WHAT ?????
Renogy SAID I would be getting a refund in 7 days!!!!!
I would, once the cash is in my bank, open up the battery and try and have a play.
ONLY too many hours into playing and it's not worth my time>
but what else to do with a free half capacity battery ????
If it still works... if you added it in parallel with another would it cause issues?WELL GUESS WHAT ?????

Just order a 60a JBD and plug it in. The cells are fine, BMS not so much. I find cutting the case at the seam much neater and easier than prying it apart…. I Use a hacksaw
So does that mean Renogy isn’t scum?
Why 7 days?
Ok just seemed suspicious. I hope they follow through!Long story,
I purchased it Via Evilbay, credit card is my linked payment.
Renogy after a four week fight said they would pay me via paypal and it can take up to 7 days total,
I guess three odd days for Renogy team, then paypal
Ebay are not interested, my credit card compony are not interested because I purchased it through a platform
You CC is scum also I have done charge backs even using paypal with ebay but paid with my card. They tried to scam me and I won.
Is this a local bank issued CC? Might want to look into other options. Should not matter you paid through a platform. LOL
Must be an UK thing. Never had that issue in the US. Strange. They are stating you have the product. But I would fight because it not working. They should let you ship it back if you are in the window for a refund.The credit card compony quoted second 75 !!!

Good Morning
Thank you for your e-mail regarding EBAY O*16.
I have completed my review of your claim under Section 75 of the Consumer Credit Act 1974. Whilst the Bank fully accepts its responsibilities and liabilities under Section 75, the Act is quite specific in that before the creditor (the Bank) is liable, the debtor (yourself) must establish a claim against the supplier for misrepresentation or breach of contract.
The Bank’s liability lies with the company who processes the transaction to your account, in this case, that is EBAY.
Under the debtor/creditor/supplier relationship, EBAY have fulfilled their contract with you as they are an e-commerce platform that enables third party sellers to sell products. Your dispute is with the seller, Renogy UK and as confirmed above, the Bank has no relationship with them and therefore cannot be held liable for their breach of contract.
I trust this clarifies the Banks position and I hope that you are able to resolve this dispute to your satisfaction in the very near future.
Regards
WELL, drum roll !!!
I got my refund whoop whoop
now what to do with the dud battery????
Do I try and find a compatible cell balancing BMS ???
I will indeed
but then what ???
YES this! And for the record, they RMA'd my battery after 1 year of use I think. It took some convincing but they did.I think you might be obligated to change the title from "Renogy Scum" to "Renogy actually warrantied something!"
Glad to hear they refunded you. This is a step in the right direction for them.
Balance the cells and use it.
The issue is most likely due to the BMS, so the first step is to change that,How does one do that

Once replaced and operational you will see battery status via the app, Overkill Solar App.
You could cycle the battery and see if things improve. Try this for a few weeks.
To manually balance either charge up the low cell, use a suitable charger with great care not to exceed 3.6volts.
A safer, and less likely to damage by overcharging a cell, is to have the battery on charge and as it nears full, the cell voltages will start to diverge. By monitoring the cell volts via the BMS, identify the high cell and apply a DC load across the cell for several seconds. ( a 12v car headlamp bulb is a suitable load).
The cell volts will drop. Increase or reduce the load contact time as needed.
The 'high' cell will change from cell to cell, 'wack the mole , discharging the high cell. When all cells are above 3.4 volts with less than 50 mV differential, consider task completed.
I assumed the battery used four prismatic cells. Renogy have other variants, cylindrical and pouch cells. In this case multiple small capacity cells will be connected in groups as four 'big' cells.I think the batteries are lots of cylindrical cells
