01
LiFePO4 Battery System for Households
Special Attention: Due to the built-in protection board of the lithium battery pack is with
over-discharge protection function, it is strongly recommended to stop using the load when
the battery pack is over-discharged. The battery pack cannot be repeatedly activated for
discharge. Therefore, when the battery pack is low power, please charge the battery as
soon as possible when main power or solar energy is available.
1. The batteries can be connected in parallel. Series connection is not allowed.
Use in upright position only.
2. The batteries are not allowed to connected with PWM controller for charging.
1.4 Can be connected in parallel
