Safety Features:
Go Power! Lithium batteries feature a built-in Battery Management System (or, BMS) which ensures safety and long battery life by constantly monitoring battery performance, internal temperature, and other critical elements required in safely functioning battery.
Go Power! LiFePO4 Lithium batteries feature several safety components in the BMS, which include:
- Over and under voltage protection, which disconnects the battery from the load or charger, to prevent damage if it occurs
- Over and under temperature protection, which also disconnects from the load if the temperature limits are exceeded
- Charge and discharge over current protection, which automatically balances the voltages during recharge cycles to bring all the battery cells to full charge at the same time, ensuring longer battery life.
- Short circuit protection, which open circuits the battery terminals if a short is detected

FAQ
FAQ & Support
+-Can these be used as starting batteries?
No, they are not suited to be used in this application.
+-Are there any wiring restrictions?
Yes. You can not wire more than 4 of these batteries in parallel. These batteries cannot be wired in series.
+-What does LiFePO4 stand for?
LiFePO4 stands for Lithium Iron Phosphate, this is the chemistry of our 12 volt lithium batteries
+-What is the recommended Depth of Discharge for these batteries?
To increase the longevity of the battery, we recommend to discharge no lower than 20-30% regularly.
+-Do you need a battery kill switch for winter storage?
There is no need to add a kill switch.
+-Do the batteries need to be taken out for the winter or can they be left in the trailer/RV? (Will they freeze?)
Yes you should take them out like any deep cycle battery. Lithium batteries do not like cold temperatures. They will not take a charge below 0 degrees and like any battery they can freeze at one point.
+-Do lithium batteries go dead by sitting while stored?
Lithium batteries will discharge overtime like any battery but they do it at a much slower rate. We recommend giving them a quick charge every couple of months to keep your lithium batteries in good operational condition.
+-How do you charge lithium batteries in cold or warm weather?
It is better to charger lithium batteries in warmer temperatures. Lithium batteries will not accept charge at freezing or below. The charging temperature range on our batteries is 32°F (0°C) - 131°F (55°C).
+-What settings are used on the inverter/charger for the lithium batteries?
Use the custom battery charger setting on the Inverter/Charger units. Please see the instructions below. IC Series Go Power Lithium Battery Set Up: Go to Unit Setting and hit enter; Scroll to Final Charge and hit enter; Scroll to set to Float and hit enter; Scroll through unit setting to battery type and hit enter; Scroll to Custom and hit enter; Set absorption to 14.3VDC and hit enter; Set Float to 14.1VDC and hit enter; Set equalize to 14.1VDC and hit enter; You are now set for charging Go Power 12 volt lithium batteries.
