December 18, 20187 yr Hallo Grant, Welcome to the forum! Do you understand the risk of buying second hand batteries? Personally, I will consider buying everything solar, but batteries, second hand. Best regards, Herman

Ditto ... but there is a way IF you know what to look out for and know you are taking a risk. 1) Use a Hawkins battery tester, same ones they use to test car batteries, and test each battery making sure they stay in the green. 2) Find out the going lead price and pay that or a little bit more per kg for the batts.
December 19, 20187 yr TTT he's asking about 18650 batteries not lead acid. You can use them with out too much of an issue. But you have to test them and be quite meticulous about the process. It's not complicated but you have to bear in mind they are second hand so you probably won't get the same capacity and they are Li-ion which can pose a fire risk if not processed and used in a sensible fashion.
December 19, 20187 yr Author thank guys for the advise, i have done a fair bit of research and am aware of the risks

December 19, 20187 yr Suggest join the FB group DIY Powerwalls, also the forum https://secondlifestorage.com/ Spot welding is the painful part really. Assume you already have a decent charger? eg iMax or similar What BMS were you planning on using?
