Frequently Asked Questions
What is a deep-cycle lithium battery designed for?
Deep-cycle lithium batteries are designed to provide steady power over long periods and handle repeated charge and discharge cycles. They are ideal for trolling motors, marine electronics, RVs, solar systems, fishing electronics and other applications that require sustained power.
Can this battery replace my lead-acid or AGM battery?
In many applications, yes. A LiFePO₄ battery can replace a similarly sized lead-acid or AGM battery while offering more usable capacity and less weight. Always verify voltage, physical dimensions, terminal configuration and charging compatibility before replacing your existing battery.
What charger should I use with this lithium battery?
Use a charger with a LiFePO₄-compatible charging profile that matches the voltage of your battery. Some existing chargers may be compatible, but the charging specifications should always be checked before use.
Can I connect multiple lithium batteries together?
Certain Pro-Guide lithium batteries can be connected in series or parallel depending on the model. Batteries used together should be the same model, capacity, age and state of charge. Always check the specifications for the individual battery before building a battery bank.
Can a Pro-Guide lithium battery be mounted in different positions?
Because LiFePO₄ batteries do not contain free-flowing liquid like flooded lead-acid batteries, they offer significantly more installation flexibility. Follow the mounting recommendations provided for your specific battery.
