Battery Management System (BMS) Modules

4 string 16.8V 40A lithium battery protection board (comes with recovery function-AUTO Recovery) Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery) Product Size: 46 * 60 * 3.4mm (balanced version) Product weight: 10.3g (balanced version) Charging voltage: 16.8V - 18.1V Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use) Continuous charge current (upper limit): 40A

Over charge voltage: 4.25±0.05V Over charge release voltage:4.23±0.05V Over discharge voltage:2.54±0.1V Maximal continuous charging current: 2A Over current protection: 3A

Suitable range: For nominal voltage 3.6V 3.7V lithium battery(Including 18650,26650, lithium polymer batteries) Product Size: 64mmx20mmx3.4mm Material:Metal Charging voltage: 12.6V Maximum output current: 20A Maximum output power / charging power: 252W

The protective board can be used as the nominal voltage of 14.4V, 14.8V, 16.8V four series of polymer lithium battery group, four series of 18650 lithium batteries as overcharge and over discharge, short circuit protection. Without the activation function in the power application for high instantaneous current,and in inverter application for avoid false triggering protection.So it will use more convenient.Note:No part design on the back, can be attached to the heat sink to ensure high current work situation for a long time.
