Looking for some guidance. I’m going to increase my truck camper battery capacity from two 12v AGM’s in parallel to 3 Li-time mini’s 12.8v/100ah, also in parallel (limited space to work with). It‘s stock camper wiring with a 30 amp service with a 30 amp fused/#10 awg directly from battery bussing to 12v fuse panel. There’s 340 watts of solar on the roof and an exterior solar port for my 130 watt portable. The update also includes a new MPPT controller. I previously installed a 300 watt inverter to charge an Ebike battery using #8 with a 40amp ANL fuse. I’ve searched but still confused on if I now need a class T fuse from battery to buss bar. It seems like the class t fuses are too large for my wiring. Any help is greatly appreciate.
