Im planning to add an extra battery in my trunk. syempre in parallel. but i read somewhere if you use different kinds/ratings of battery, dapat merong isolator. pag same type naman hindi na kailangan.

ang tanong, saan ba may bentang isolator? or can it be DIYed? im planning to add an extra battery. meron kasi dito brand new Motolite Excel N70 ata ito malaki. extra battery dito sa amin. honda city 2006 ang ride na lalagyan ko. it is for my sound system tsaka para longer running ako with accessories with the engine off. i dont have time to buy a deep cycle battery. kasi meron naman dito extra battery

ang iniisip ko lang pag walang isolator eh baka ma overcharge ang original battery ko which is only an NS40. kasi when putting a battery in parallel, iisang load siya para alternator

can you please clarify things for me? hehe thanks!
