Just purchased a Li Time Self Heating battery and then received the diagram below that states it requires a charging source above 20A. My panel is 150W (9.3A) connected to a 30 amp PWM controller. Does that mean that even if the panel is getting full sunlight the BMS won't have enough Amps to activate the self-heating pads in the battery? If so, can I use my controller to override the battery BMS? (Having a tough time getting a direct answer from LI-Time.)
