Consideration should be given to the following when the component is used in or with another product. 1. The battery module SR-48-100-LP4-IN-02 (LifePower4 V2) had been evaluated based upon manufacturer’s specifications for charging, discharging and temperature limits. They have not been evaluated in combination with charger(s) or other control systems in the end use application. -

50% SOC (state of charge) before placing it in storage. Lithium batteries will lose a certain percentage of their total charge while in storage, depending on how long they are stored and the conditions they are stored in. EG4 recommends recharging the batteries after 8 – 9 months in prolonged storage. -

Where ambient temperature is above 86°F (30°C), cable size must be increased according to NEC 310. The 4 AWG cable included in the package is intended only for the connection from the battery module to an EG4 battery rack busbar. DANGER! When adding or removing a battery from any rack, cabinet, or busbar, turn off ALL batteries, and use a voltmeter to confirm there is no voltage present. - Page 13 CAUTION: Never position the battery upside down or face down!

Use the included battery cables or size the battery cables appropriately! Refer to an NEC approved ampacity chart for specifications. NOTE: EG4 recommends using a properly sized (amp rated) busbar to parallel batteries together. Paralleling via the battery terminals will cause inconsistent charging and discharging issues in the bank. -

Page 16: Communication Cable Pinout And Dip Switch Id Tables
9.2 COMMUNICATION CABLE PINOUT AND DIP SWITCH ID TABLES LifePower4 48V V2 batteries interface with an inverter by designating a “Host” battery (DIP ® switch ID No. 1). The ID code range is 1 ‒ 64 and the communication mode can support up to 64 modules in parallel. -
Page 17: Protocol Change/Selection Procedure
The inverter protocol ID is used for establishing closed-loop communications with supported inverters. The inverters listed in chart 10.1 are capable of closed-loop communications with the battery. All other inverters will not support closed-loop communications with LifePower4 V2 batteries. 1. Power off all battery DC breakers and BMS power buttons. Ensure that the voltage between positive and negative busbars is 0V. -

100% before paralleling them together. This step is crucial to optimize battery performance and ensure proper operation. If communicating multiple EG4 batteries together, the Multipack firmware will need to be used via an RS485 Update. For the example below, all batteries will need to be updated EXCEPT the EG4 LifePower V2. - Page 21 RS485-A NOTE: When using LL-V1 and LifePower4 batteries in communications with the LL-S/LL-V2 multi-pack firmware, ensure the communications cable between the LL-V2 and all older model batteries down are pinned to this standard. If there are extra pins populated, the LL-S will trip its breaker if it receives a signal from pins 3 or 6 along with all other batteries in this parallel configuration.
