Review on π High-Quality WSDMAVIS 18650 Polymer Lithium Battery Cell PCB BMS Board with 50A Charge Protection & Balance Feature - 1Pcs, 4S/5S, 3.7V by Mdl Thurston
Overrated output current, can't load 20VDC motor. Current over 20A
This 5S Bms is rated for 50A of power, but it hardly allows the Makita brush impact drill to idle at 20A. The over-current protection cuts off the power supply when I try to charge it. Now I only use this BMS for charging, my new 5S battery can handle over 140 amps of output power. So now the output is connected directly to the negative battery and it works great with all my cordless power tools.
- The protection board has a heatsink and a connecting wire. (See description below for detailed parameters)
- Protection
