I have two series 27 trolling motor batteries. One is going bad(bought them at same time). I have a new spare 29 series I use for my small boat. Can I temporarily use a 27 and a 29 for my trolling motor on my bassboat. Im fishing this weekend and too far to pick up a new one. In otherwords can you use a 27 and 29 hooked together or a 24 and a 27 hooked together? Thx
