yep! another agm charging question

[madmaths]

Hi! I have some question about charging a agm battery I did some google research and from what I found my agm battery should be charge at 14.4. ( please correct me if this is wrong)

my question : I have a 100w solard panel and this charge controler http://www.hqsolarpower.com/30-Amp-PWM-Charge-Controller-with-LCD-Display-p/hqst-ctrl-pwm30lcd.htm
this charge controller dont have agm setup so I think the best setup whit he best voltage value is the sealed setup, make sense? ( please refer to the pic)


second question the controller have 2 setting : the over discharge voltage setting ( not sure at what valut I should set it ) and I have over discharge return voltage , what is this for??

thanks a lot!!

An AGM battery is a "sealed" battery. (Technically, a valve regulated battery, but close enough.) Use the "sealed" "SLD" setting. If your controller has temperature compensation, be sure to use that - it gets brisk in Canada.

Can't help you with the "over discharge" settings.

You should be able to find the **range** your battery mfg recommends, and/or discuss such issues with a tech support person. For me being unable to easily do these things would knock a brand out of the running.

Those two settings are for load control, keeping non-essential loads from drawing down the bank. Check total amps allowed on the outputs, often too low to be very useful, a standalone LVD is often better.

First setpoint is the low voltage cutoff, second is the higher point when it turns the load output back on.
