    This is my second Mighty Max 12V Lithium 100aH battery. A simple display has been added to display state of charge (3 bar graph), voltage as xx.x, and days since with a simple one button toggle. It’s located on top of battery. I have a simple solar charging setup( 4 x 100W solar panels, 30 A MPPT solar charge controller, 2 x 100ah lithium batteries). I have observed the MPPT (USER charge settings) is reporting 300 to 1000 watts charge daily (even on cloudly). I have observed 13.2 V at dusk and depending on overnight load a minimum voltage of 12.8, daily max voltage is limited to 14.2V and max amperage observed was 28A. Prior to adding 2nd battery in parallell, I did run my first battery to 10.8V (BMS cutout voltage) twice as reported by the MPPT charge controller, the battery seemed to recover as expected (caused by empty propane tanks and furnance attempting to operate continously, in cold cloudly weather). With the added wattage of the 2nd battery, my RV appliances seem to be operating better, diagnostic and monitoring instrumentation are planned for next year. Overall, I expect these batteries to last longer than the 2 x 75A setup of the original RV. 2022-05-07

Mighty Max Battery

Arrived quickly. Even got a sticker with it.
Solid looking battery, came well packaged. Have used their battery before for my lawnmower and now looking forward to see how it lasts in my snowmobile.
I can't believe it less than 48hrs since I ordered from Walmart and it's in the machine. What more can I say except great price.
Thanks Larry
Item as described and perfect fit and arrived on time
Battery arrived in a good shape package strait to my door steps
Arrived just in time to power my generator here in the cold Maine winters. Excellent service!
Arrived quickly from WALMART.COM. Perfect size and proper placement in my generator. Installation was easy. Generator fired right up. Battery came fully charged.
New battery. Ready for cold weather!
So far these Might Max batteries are good but it’s only the first day and they were on charge for 12 hrs. I’ll have to come back and do an update at some point in time. Ordered them on Amazon and got them the next day. I was encouraged by Mighty Max to make this google review and post pictures to extend my warranty for 3 months but there is no way to post pictures 🤣🤣🤣 It’s been a few months and I was able to go back and edit, so here is a video I made, the rest of the photos I have deleted. Batteries are still going strong. Update 12-11-2025
They arrived within 2 days of ordering them packaging was really good I haven't put them in my MX350 yet I hit them with my multi meter fresh out of the box and got 12.4v on both batteries so that is good
