Description
Overview
This WattCycle battery has a rated capacity of 314 Ah at 12.8 V nominal voltage. Its rated energy is 4019 Wh. It uses LiFePO4 cells. The manufacturer offers it for motorhomes.
Features
- Self-heating: a built-in heater warms the cells so the battery can be charged in sub-zero temperatures.
Runtime and charging
- At a steady 500 W load, the rated energy lasts about 8 h. An inverter and the cabling add losses, so plan with a margin.
- Continuous discharge: up to 250 A, about 3200 W at nominal voltage. Keep inverters and other loads below this.
- Short peaks of up to 260 A are allowed for 1.2 s, for example while a motor or an inverter starts.
- At the recommended charge current of 62.8 A, charging from empty takes roughly 5 h.
- The maximum charge current is 250 A.
Installation
- Fit a fuse or circuit breaker close to the positive terminal and size the cables for 250 A of continuous current.
- Charge it with a LiFePO4-compatible charger at the voltage the manufacturer specifies. For mains power see AC–DC battery chargers; for charging from a vehicle alternator see DC–DC battery chargers.
- It is a deep-cycle battery: do not use it to start an engine unless the manufacturer rates this model for starting.
