65amp wiring/trouble shooting

Also be aware that high charging rates can damage batteries.
Even a good battery thats getting a high charge will heat up, and that prevents it from fully charging and can permanently damage it.
A high charge on a frozen battery can be a major disaster.

Whenever possible, use a battery charger on a very low or dead battery. Battery chargers have some sort of control on the current, either automatic or manual.
