Sounds like you may have a problem with your chargers. Or the wire gauge you are using for the charge wire is to small, generating excessive resistance. Just for the heck of it, try using 12-14 gauge wire for the charging leads from the charger. The Triton should be able to handle 1 amp plus charge loads. If you still have them, check the directions to see if there may be any issues that may be creating the problem.
