Joule Case SLA modules are intended for the casual user. In order to maintain charge level and the best performance the SLA modules should be connected to the ‘float’ charger when not in use. The charger draws little power when in maintenance mode. It serves to keep your SLA modules ready and at 100% when you’re ready for an adventure.
If the SLA modules appeal to you consider that lead acid can decrease in capacity under constant heavy loads. When choosing your system runtime size it to last at least 10 hours for best performance. Example: with 2 Pb modules ~100Wh to last 10 hours, the load should be under 100 watts continuous.
See the image below for ‘load’ characteristics of lead acid batteries. For any questions about performance or properly sizing your Joule Case system let us know.
