About Us

Power That Shows Up

OTIQVER builds LiFePO4 (lithium iron phosphate) batteries for people who need reliable off-grid and backup power — RV owners, marine operators, solar installers, and homeowners preparing for the next outage.

We don't sell a catalog of everything. We sell a small number of batteries, built to a spec we'd use ourselves, at a price that doesn't require a financing plan.

Why LiFePO4

If you're still running lead-acid, here's the math:

  • Cycle life: Lead-acid lasts 300–500 cycles. OTIQVER LiFePO4 delivers thousands of cycles.
  • Usable capacity: Lead-acid can only be discharged to about 50%. LiFePO4 gives you 100%.
  • Weight: A comparable 24V 100Ah lead-acid battery weighs around 66 lbs. Ours weighs 39.68 lbs.
  • Maintenance: Lead-acid needs monthly water checks. Ours is zero maintenance.
  • Self-discharge: Lead-acid loses 5–15% per month. Ours loses about 3%.
  • Warranty: Lead-acid typically carries 1–2 years. Ours carries 5 years.

A lead-acid battery that you can only half-discharge, that weighs 66 lbs, and that you replace every two years is not cheaper. It's just slower to bill you.

What Makes OTIQVER Different

80% Capacity Retention, In Writing

Most competitors warrant 70% capacity. We warrant 80% for 5 years — and we publish the number so you can hold us to it.

Slim Design That Actually Fits

The OTIQVER 24V 100Ah measures just 6.7 inches wide — narrow enough for RV battery boxes and marine compartments where wider batteries simply won't go.
