Purchased an additional four more Molicel, P26A, 18650, 2600mAh, 35amp batteries to convert a Porter-Cable 14.4v battery pack to li-ion. Installed with them a 4s, 40amp, BMS card to control charge voltage, etc. Used a repurposed 15vdc, 200ma power supply to charge them. Retrofitted battery pack powered drill with ease with plenty of amps for torque required. Batteries arrived quickly and were well packaged in 2-pack plastic containers.
