14.4v 6.6ah 95.04wh Li-Ion Module with BMS

Around $80/kWh for packs with a BMS! Here are awesome Panasonic 4s3p 14.4v 6.6ah 95.04wh packs with a working BMS. The positive and negative wires allow charge and discharge current so you can use these packs as is. I would recommend keeping the charge and discharge limited to 3 amps per pack or 0.5c. The two blue wires are just for the temperature sensor so you don't need those 2 wires. Just cut the positive and negative wires off the connector and those will be your main wires. Cells used are Panasonic CGR18650CG which are excellent cells trusted by the medical industry. These are used medical packs with different dates but mostly around 2013 dates. Either way they were only used as backup so the packs likely have not cycled too many times. If you get a pack that does not read voltage simply apply a charge and they will wake up immediately. The cells may be sitting just under the BMS low voltage cutoff. The packs can charge up to 16.8v so just set your charger to 16.8v and maybe 1-2
