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
Do not wire in series.
Maximum 4 batteries per bank in parallel.
Only suitable for 12-volt applications.

FAQ About Lithium Batteries…
Can these be used as starting batteries?
No, they are not suited to be used in this application.
Can these charge from an alternator?
Be sure to use a suitable 12V DC-DC isolated voltage converter when incorporating lithium batteries as ‘house’ batteries in an RV or boat. Many alternators cannot handle lithium directly, and the voltage converter will ensure full & proper charging.
The Victron Orion 12/12-30 is an excellent choice.
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 common chemistry of ’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% SOC regularly.
Is a battery kill switch for winter storage?
No, there is no need to add a kill switch.
Do lithium batteries need to be taken out for the winter or can they be left in the trailer/RV? (Will they freeze?)
It is recommended to take the lithium batteries 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 from sitting while stored?
Lithium batteries will discharge over time like any battery but they do it at a much slower rate. We recommend giving them a quick charge every couple of months and to keep them in peak condition.
How do you charge a lithium battery in cold or warm weather?
It is better to charge 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. See the instructions below for more info.
