2nd hand batteries

Save me money website sent me email recently that they had 3k of pylontech refurbished in stock with 20% off retail price if you want to try them. Never used them myself and holding out for new pylon stock due in next week. Would consider a used battery if less than a year old but would need to be decent savings to warrant it.

I would not mind the age of the battery if it was not abused. 1 year old can look worse than 3 year old. For pylontech batteries it is easy enough to connect to them and check what the state the cell are in and general SOH.

EV breakers yards are springing up,but you need to know what your buying and go safely.

Quite right,and with all lithium,dangerous. However in a small scale simple setup like mine, a possible alternative to lead acid. Thanks.

That seller is either not telling something, or is a dimwit.

I sold mine at just over a year old for a good bit more, and considering that they're in such short supply currently they could easily get €750-800.

I don't think they are a dimwit as they seem to be involved in Solar Supply/Installations going by the other ads they have. Maybe they don't deal in Pylontech's and just want to move them on?

I take the 3.7 v lipo cells from the modules and make up packs of differing voltages for various workshop projects. Charging and battery balancing is via Turnigy charger, fed by PV solar project.

No mains involved and around €300 spent in total. Just thought time to move on from lead acids and hernias!

It is like buying a car they all ads say they are clean inside out and fly through NCT. But you only know if that is true if you look under the bonnets, kick some tires and take it for a spin :)

You can get a lot of info out of them just by connecting rs232 cable and running some commands. It will show SOH, cycles, each cell level, errors etc.

You will need same battery from same manufacture as they would need to be connected to each other and need to speak in the same language. Idealy you should not mix different sizes.

If people are stuck for sourcing new pylontech batteries as I was, I know of mayo supplier that had just got pallet in this week of them. If anyone wants his details drop me a pm

Bump. Gonna put this up on adverts this weekend. PM me for details.

@garo Did you sell the battery or is it still available

No problem, thanks for getting back to me

Fella on the Facebook Irish solar group selling 3 x Pylontech us3000 currently if its any use to anyone.
