so i have a 115A alternator and i have a hc1800 under the hood. im looking to add a 2nd battery and wondering what my alt can safely handle. would like to get a hc800 in the trunk- just wanna make sure the stock alt can support both batteries.
doing this to safely run my DD M1c at .5. i have a voltage meter on the dash. at what point should i get worried? 12V? really dont wanna fry this amp
