I am considering an onboard charger but I have a few questions
I have a 16/48 war eagle. I have a starting battery in back and 2 batteries up from dedicated for my TM and 998.
my question is:
1. I will have to place it in an open spot, but the wires may not be easily hidden with the length on unit- so can I put extension wires on them?
2. I have 3 batteries total- 1 for cranking, 1 for TM, and 1 for 998- So would I need 3 banks?
3. what are the best amps per bank? 5 or 10
4. best manufacturers or your recommendations?

Thanks
Tom
