Charging multiple batts.

[d-nice88]

Ok its probly been asked a 100 times but i dont feel like searching the forms im to tired from work ;/ so ill ask. If i got all 3 of my agm batts hooked up in parallel can i charge them all up at the same time if i hook up my ctek 7002 to the bat under the hood ?

[audiofanaticz]

Yes

Cool beans thankx a bunch

Simple answer is yes like audiofanaticz said but I usually like to charge a group of batteries by (using yours as an example) connecting the pos to battery 1 and the neg to battery 3 (or vice versa) to get an equal distribution across the entire bank.

I'd be curious to see if that makes a difference. I asked my stepdad about this and he said it makes no difference. I can't ask him again but I'd still be curious to see the answer.

This is a parallel charging board for rc cars, the same principal applies and here is how they laid it out. For this product they recommend that each battery be within .2v of each other before starting a parallel charge but it's for LiPo batteries and they really don't like to self balance (not sure if AMG batteries are like this or not)

[ShadeTreeMechanic]

Just hook it to any positive and any negative. Parallel is parallel.

If all 3 batteries are already wired in parallel, they should all have the same voltage. They will charge/discharge each other until they are all equal. So mismatched voltages shouldn't be a concern, unless you have a bad battery in the group.
