they make batteries that'll take a 300 amp charge??
how much equip do you plan that needs 300 amps??
how will you monitor the battery and charge conditions?

why is the meter reading at all, let alone backwards, if you've bypassed it?
how does anything electrical work if you've bypassed the ammeter?
