Need an "Onboard" charger for 72Ah @ 12V or 36Ah @ 24V

I've got 8ea - 9Ah AGM batteries on my e-bike.
Currently I'm using a 12V - 15amp IOTA charger with the IQ-4 three stage plug-in.
The way my bike is set up, I can use either a 12V or a 24V charger.

I need a charger that is made for charging AGM batteries, preferably a 3-stage type.
I am thinking that something in the range of 5-10 Amp would work well.
I'd be happy with anything in the range of 4-8 hour charge time.
The ideal charger(s) would be relatively small.

I love the way my current charger maintains my batteries.
It's great, but want to use it to maintain my two 220Ah 6 volt batteries that I have for home use.

I'm looking for suggestions for a good charger that I can mount on the bike so I can just plug it in as needed.

Thanks in advance for any help!

If you care to wait, I ordered these from here

http://www.batterystuff.com/battery-chargers/12-volt/11-20amps/JAC1212.html

My search for a charger has been quite exhausting, I never was able to find the optimizers except from the factory direct at double the advertised price.

They have some completely sealed waterproof chargers also, I was interested but could not get exact charge profiles on some of the waterproof chargers listed.

I believe this company is in your neck of the woods, I ordered mine on Friday, hope they get here this week.

The jac1212 claims to have a 100% duty rating, my questions were not answered on two problems, they said they would get back to me next week, questions are, can I use both chargers at the same time on 2 seperate packs, and can they be left connected during use. The soneils can be left connected during use with out parasitic loads draining the battery, and, multiple soneils can be hooked up. Only time will tell if these can be. I am desperate, so I ordered without waiting for my answers.

Thanks Chuck,

Looks like these folks have a pretty good selection and fair pricing.
Their "How to select a charger" section was helpful in determining what size I need.
I think for my usage, a 10-12 amp waterproof would work great.
Of course, they all have a fairly large footprint, but now that I have my huge controller on one side
I need a huge charger on the other to balance things out ... ;)

I appreciate the link!
