9. positive cable from the Isolator to the Auxiliary battery need to be fused 12 batteries can produce large amounts of power are capable of melting cable insulation in the case of a short circuit Since a dual battery system contains two batteries connected together the cabling needs to be protected for short circuit at each battery The battery isolator has inbuilt over current protection which will protect the cable from the starting battery To protect the cable from the auxiliary battery an inline fuse or fused battery terminal is needed Is the battery Isolator safe to use with modern electronic vehicles The Projecta battery isolators have been designed to work with all vehicles especially new vehicles with onboard computers In fact the isolator itself has a small microprocessor that intelligently controls the charging The isolator has in built surge suppression and over current protection for extra safety Can use a charger to recharge my battery s with a Dual Battery System You can charge the auxiliary battery with a battery charger without effecting the battery isolator at any time When charging the starting battery the isolator will automatically connect the auxiliary battery when the starting battery reaches 13 4V about 75 charged and will then be charged also This is not an ideal way to fully charge the batteries It is recommended that when charging the starting battery the Auxiliary battery is disco
