Multiple Chargers
I’m traveling and the charger has failed. Until I can get it repaired I’ll buy and use a standard auto charger. Have you used multiple chargers on a battery bank or do you know which ones work in that...

If you want to PROVE whether multiple chargers do or do not contribute to the total amps going to your battery try this.
Take a good heavy jumper cable and hook it to your battery bank where you would normally connect the positive clamp from your charger. Connect the negative clamp or clamps to the batteries like you would normally. Now instead of connecting the positive clamp to the battery connect it to the other end of the jumper cable. It will now work the same as you normally connect things. What you can now do is put the amp loop of a digital multi meter around the jumper cable and SEE what is going to the batteries. Connect the second charging device the same way and so on with as many as you want. After adding a charging device recheck the amps passing through the amp loop. This simple test will show you whether it does or does not help to use multiple chargers. It is important to use a heave wire jumper cable so it doesn't induce resistance into the path. The batteries need to be at a low SOC to make this work. If they are fully charged this won't tell you anything. If you are a DIY guy like me it is a interesting project when you are bored because it is Winter and you are not our RVing (-:
