Battery Protection Mode: Ensuring Deep Cycle Battery Safety and Longevity

Table of Contents

Deep cycle batteries are a necessary expense when you own a bass boat, RV, or other battery-powered machine. But let’s face it: good ones don’t come cheap. Battery protection is your priority if you want to safeguard your investment.

Here’s some great news: our lithium batteries come with battery protection mode. Go ahead, breathe a sigh of relief! We’ll tell you what that is, and what other battery types have it below.

Understanding Battery Protection Mode

Our LiFePO4 lithium batteries have a built-in battery management system (BMS). This system protects your battery from events that could cut its lifetime short. It also manages your battery’s performance and ensures safe operation.

Most importantly, the BMS keeps your application (and the people who use it) safe from battery accidents. It will shut the battery down when it detects unsafe conditions. This is called “battery protection mode”.

Battery Types and Battery Protection Mode

The short answer is “no”. Most batteries don’t have this essential battery protection. Here’s looking at you, lead acid batteries.

Lead acid batteries come with a cheaper price tag. But they rely on YOU to be their protector. You’re responsible for shutting them off if they get too hot, and preventing them from being discharged too much. Otherwise, they’ll continue to work until they’re ruined. (Or worse–they could damage your vehicle or injure those who use them).

AGM and Gel batteries also use lead acid chemistry. So they don’t have battery protection mode either.

Ionic lithium deep cycle batteries offer battery protection mode (and peace of mind).

Common Reasons for Battery Protection Mode Activation

Why might your lithium battery go into protection mode? We’ll give you the most common reasons here:

  1. Over current
  2. Short circuiting
  3. Voltage too high or low
  4. Temperature extremes
  5. Loose connections
  6. Defective battery cells
  7. Wire insulation breakdown
  8. Defective battery fan

The BMS has guidelines for safe battery operation. If conditions veer outside those specifications, it activates the battery protection mode.

What to Do if Your Lithium Battery Goes Into Protection Mode

Battery protection mode signals an adverse or unsafe condition. Your battery won’t come out of protection mode until that condition passes.

In most cases, you need to wait for the condition to pass. The battery will turn itself back on when it’s safe to operate.

However, there are some things you can do to make conditions safe again.

  1. High voltage
  2. Low voltage
  3. High temperature
  4. Low temperature
  5. High current/Short Circuit

Keep in mind that internal battery problems are rare but possible. If you can’t get your battery out of protection mode, you can contact our battery experts for advice.
