I'm looking for a used reliably working BMS for my home built Li-Ion pack (18650 Lithium Cobalt) and the corresponding charger. I will be operating from 10s (37V nominal) to 12s (44.4V). Maximum charging voltage is 4.20V per s, minimum discharging (LVC) is 3.00V. +/- a few % of course. Pack capacity is 10Ah now, but will increase to 15 or 20Ah in the near future. I would need at least 3A charger so the largest pack can be completely charged overnight.
Alternatively, I could use one or two 5 to 6s LiPo charger/balancer(s) to achieve the same thing.
I'm new to Lithium battery so the above description might not be complete. The bottom line is something that I can use to reliably charge and balance my 10 to 12s pack. Discharge monitoring is nice but not absolutely necessary at this time. So if you have either one lying around since your recent power upgrade, PM me and we'll take it from there. Thanks.
