Real words from VMAX customers powering trolling motors, house banks and off‑grid rigs.
MAN O MAN what an incredible product! I've been on the fence about lithiums for a long time and my ONLY regret is not finding VMAX Tanks SOONER. Customer service is absolutely beyond excellent — WAAAYYYYY above and beyond. Customer for life!
VMAX has great customer support. I've purchased their lithium and AGM batteries and they're great! Awesome product!
I recently upgraded to their newest Lithium waterproof with BMS 120Ah battery. A 10‑hour day with all 4 of my Lowrance HDS 12 units running ended with around 60% charge remaining. AMAZING!
As a Pro walleye angler I don't have time for battery issues. VMAX has eliminated these problems. Hands down the best battery company on the planet.
Running 3 100Ah Lithiums for my trolling motor and their Group 31 Dual Purpose AGM for cranking and house battery. Packed with power at great prices!
Wow — awesome company, service and high quality batteries! Replaced with 3 SLR200 200Ah AGMs in my sailboat and now 4 SLR155 155Ah AGMs in our RV. Loyal customer!
We have purchased deep cycle AGM batteries for our sailboat and now for our RV. VMAX batteries LAST longer and are a much greater value than others. Thank you VMAX!
The boat sank. A week later, both batteries were fine and the Minn Kota worked fine while batteries and motor were still underwater. An amazing indication of the quality and durability.
