I don't really have a purposefor this battery build, just experimenting with the chemistry and the cost factor (vs the other packs I've built from the 18650 Ring packs). I likely will just keep this thing around as a ~15-18Ah portable power bank.
I am waiting on an (aliexpress shipment) Daly BMS to connect to this pack. In the meantime, I spot-welded this thing up and used my bench DC power supply to bring each of these parallel groups up to 3.64V. The CC dropped to 0.0A on each of these before I disconnected them.I don't have any other charging option since these don't fit into the ZanFlare unit and the(TrustFire)charger I bought on Amazon was junk, so I sent it back.
Its been roughly 5-7 days since each of these parallelgroups have finished charging. Yesterday they all were sitting nicely in line around 3.5V and now today they are sitting at 3.48-3.49V.
Should I be worried about this slow creep? Is this normal for the LifePO4 chemistry ?
