Battery Management Systems

Battery Management Systems are typically used for Lithium based rechargeable batteries. Such as Lithium Ion (Li-Ion), Lithium Polymer (Lipo) and Lithium Iron Phosphate (LiFePO4). Battery Management System (BMS) manages each cell of the battery packs voltage to ensure they are equalised across the whole battery pack as well as cuts the circuit when the battery (or cell) has reached the safe cut off voltage. Battery Management systems are essential in cost critical lithium battery installations. Major manufacturers of laptops and lithium ion power tool batteries adopt their own BMS in their battery packs to maximise performance and prolong battery life.

Mr Positive currently carries growing selection of DIY BMS modules to suit different types of lithium batteries as well cell number battery pack. Full specifications, data sheet and wiring diagram can be downloaded for each model. Contact one of our in house battery experts for advice on which BMS module is best suited for your applications.
