13S Lithium-Ion Battery Protection Board with Balance Lead

Add the specified protection and balancing functions to a correctly designed thirteen-series lithium-ion pack. This board is intended for supported 3.7 V nominal cell chemistries in a 48 V-labelled arrangement.

✅ Monitor the cell groups - A matched BMS manages the listed overcharge and overdischarge functions.

✅ Include balancing support - The circuit provides the specified group-balancing function.

✅ Connect with the sampling harness - The package includes the lead required for the correct cell-group connections.

Match the Chemistry and Current Rating

The described continuous working limit is 40 A, with 50 A maximum and up to 40 A charging under the specified conditions. Verify actual derating and the complete datasheet before building the pack.

The board is intended for listed ternary, lithium-cobalt-oxide or lithium-manganate cells, not a LiFePO4 substitution. Pack wiring, fusing, insulation and the separate charger must all match the design.
