A friend gave me a 2-year-old Interstate Deep Cycle/Cranking (SRM-27) Battery. :D

1st -- Can I hook this Deep Cycle/Cranking battery up in parallel with my 1-year-old “BPS Cranking battery”?

Currently have a 5-year-old 3 bank Guest charger connected to my starting battery and 2 trolling motor batteries.

2nd--If I Add the Deep Cycle/Cranking, Will this configuration cause a problem?


Thanks Guys,
Rick Hale
