Battery management

Recommended Posts

Due to the power demands of today's electronics and the use of multiple sonar units, many of us run a house battery as well as an electronics battery. Is there a single gauge available (2"-2-1/2" dia.) that monitors voltage for 2 batteries? Due to space limitation, this would be a great gauge to have. So, in short, I'm looking for 1 gauge with two volt scales on it.

All you need is a single 12v DC gauge with an "A" and "B" switch.   Very simple.  This one is priced right too. https://www.amazon.ca/MICTUNING-Display-Voltmeter-Waterproof-Motorcycle/dp/B078LVLHNF?ref_=s9_apbd_otopr_hd_bw_bA0An0t&pf_rd_r=8W8B20VZ3ZEGB4PG4NDT&pf_rd_p=b9d872f6-bc7c-5da0-ac83-45c2f1e947f9&pf_rd_s=merchandised-search-10&pf_rd_t=BROWSE&pf_rd_i=9163900011

There's also this one although on a small rectangular platform with 2 of the above gauges, about 2 x 4 inches. https://www.aliexpress.com/item/4000453281421.html?spm=a2g0o.productlist.0.0.344654595pYfaX&algo_pvid=0b4a6d9b-7054-4058-b545-bf4c79eb6515&algo_expid=0b4a6d9b-7054-4058-b545-bf4c79eb6515-0&btsid=0ab6f83a15934515673462575e6031&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_

Thank you. As simple as it was, I never even considered an 'A' and 'B' toggle.

I have a new boat coming in 2 weeks thinking about putting 2   led volt gauge s in  but i do like  the idea of a  Toggle switch  Great idea.  That is  what i like about this group very helpful.  So here is a Question Best place to get Deep cycle battery's and is it worth the extra to go 31 series and or agm battery's
