Hello Together, the other day my starter battery was empty (had my luck demanded out ) and despite full build-up battery (2x150Ah), inverter (3000W) and shore current, I would not have come any further. Dss whole happened under “laboratory conditions” in the workshop and a proper battery charger was tangible. So no problem. But if this happened to me the same way on the road, I would have been thrown up at the moment. Despite enough energy in the build-up battery. Therefore the following question to e uch: How would you help your starter battery in case of an emergency? Briefly to the current setup: 2x 150Ah LiFePO4 Votronic 121270 Chargebooster Victron MultiPlus 2 3000
