So far so good
Only been out couple times since installing. After 6 hours on the water running 3 screens and live well, only brought battery down to 80%. Phone app is great to monitor battery but ultimately time will tell. Extremely satisfied to this point.

Cranking battery
Bought the 12 volt 190 ah lithium battery, customer service was great, had battery the next day, fished a 8 hour tournament running all my graphs ( 4 of them ) with livewell pumps going all day and still had 60% left. The Bluetooth information Paige is a great feature as well

First class
I purchased the Dual Purpose 190ah. The great people at Millertech had the battery shipped out the next morning and it was delivered to my house the very next day. They provided email tracking and even sent an email once the battery was confirmed as delivered. Such a great company!! Thanks for everything

190Ah battery first day on the water.
Started about 09:00 on the water. Boat setup 2 Echomap Ultra 126SV, LVS32, LVS34 and GT54 on the bow. 1 Echomap 106SV Dash GT56, running the live well (1000 gph) and all of the boat electronics are on the 190AH. Started the day with 189.1Ah on the App and when I finished at 14:06 was at 139.2Ah left on the battery. So using 49.9 Ah Comparing that to my old AGM 100Ah that would only last 4 hours.
