10PCS/LOT 1S 3.7V 3A li-ion BMS PCM Battery Protection Board pcm for 18650 Lithium ion li Battery

This is essentially a ramped up version of Ardumoto motor driver shield. For
this monster shield we\\\\\'ve replaced the L298 H-bridge with a pair of
VNH2SP30 full-bridge motor drivers. We\\\\\'ve also beefed up the support
circuitry so this board is capable of driving a pair of high-current motors!
The VIN and motor out are pitched for our 5mm screw terminals (not included),
making it easy to connect larger gauge wires.

Note:When using this board in extreme high-demand applications it may be
necessary to improve thermal performance with a heat-sink or fan and to solder
the wires directly to the board instead of using a screw terminal (in addition
to the myriad other complications present in a high-current system) However,
when using the board at currents up to 6A the chips will barely become
noticeably warm.
