Protocols for the Proper Storage and Maintenance

Li Expander Pak 2400

The Li Expander Pak 2400 has a low self-discharge rate at 77 ºF (25 ºC) and can be stored for up to

6 months before it needs to be recharged (if it was charged fully when placed in storage). However,

the self-discharge rate increases as the storage temperature increases. The increased self-discharge

rate at high temperatures is a phenomenon common to all rechargeable batteries.

This Technical Bulletin provides easy instructions to ensure that the Li Expander Pak 2400s function

optimally in all environments. Conversely, failure to follow these instructions will result in irreversible

damage to the Li Expander Pak 2400s within a short period of time.

This Technical Bulletin provides protocols for:

1. Li Expander Pak 2400 storage and charging maintenance in climate-controlled

environments (page 2)

2. Li Expander Pak 2400 storage and charging maintenance in high temperature environments

(page 6)

3. Solutions (by reference to other Technical Bulletins) if one or more Li Expander Pak 2400s

displays a ﬂashing RED Battery Status LED (page 6)

4. A Preventive Maintenance Checks and Services Table for two storage-temperature

scenarios (page 7).

1. Protocol for Li Expander Pak 2400 storage and charging maintenance in climate-controlled

environments

The following protocol shows a sequence of steps that will allow simultaneous charging of all ten

(10) batteries of a single system using shore power or generators as the charging source. The basic,

system-charging connection scheme is shown in the diagram below.

Case (gure 2).

1. Slide the stack of PAM Solar Array Cases on the left, to the

left (red arrow; gure 2) to expose the 120 VAC L5-50 Port

on the PRO-Verter 7000.

input connection on the PRO-Verter 7000

3. Connect the 30 A and/or 15 A adaptor

to the PRO-Verter 7000 50 A port

(Figure 5).

The AES components should be arranged so that the necessary ports are accessible. Two adaptor

cables (gures 3 and 4) allow connection of a 120 VAC 15 A power cord into the 120 VAC 50 A Port

on the left-hand side of the PRO-Verter 7000. The method described here will work no matter how

the individual components are arranged as long as they are close enough for the cables to reach

between the ports.

2400s to the other Inter-Connect Strip using a 5’ Inter-Connect Cable for each as shown in the

diagram above.

5. Connect the two (2) Inter-Connect Strips to the 24VDC IN ports on the front left side of the PRO-

Verter 7000 using two (2) 5’ Inter-Connect cables as shown in the diagram above.

10. Turn off Li Expander Pak and reinsert cotter pins.

Page 5 of 8

6. Remove the cotter pin from the Power Switch of all Expander Paks and PRO-Verter 7000-120

and toggle the switches to “ON”.

7. Determine the Battery Status by pushing the button for the Battery Status LED report. Each one

should be GREEN or AMBER.

8. Adjust the input amperage

on the PRO-Verter 7000. See

diagram to the right. The diagram

provides setting values for charging using

shore power) and fuel-powered generators.

9. The PRO-Verter LCD user interface will display zero (0) charging amps when the batteries are charged fully and the

LED Status indicator will be GREEN.

NOTICE

*Extending the charge times beyond the minimum will not result in damage to the Li

Expander Pak 2400s. However, they should not be left to charge indeﬁnitely.

Minimum charge times based on AC input amperage

5 amps AC (600 watts of charging power) ~40 hours charge time if the batteries were fully discharged*

10 amps AC (1200 watts of charging power) ~20 hours charge time if the batteries were fully discharged*

15 amps AC (1800 watts of charging power) ~13 hours charge time if the batteries were fully discharged*

30 amps AC (3600 watts of charging power) ~6.7 hours charge time if the batteries were fully discharged*

NOTICE

Failure to properly set “AC Input” may overload the AC power source.

* If the Expander Paks are stored at temperatures above 90 ºF (32 ºC), then the time between

maintenance checks and/or charges must be reduced to one (1) month.

The importance of reducing the time between maintenance charges (i.e., charging more frequently)

and maintaining the Expander Paks in a fully charged state increases as the storage temperature

increases. The higher the storage temperature, the faster the Li Expander Pak 2400s will self-

discharge.

It is absolutely imperative to follow these instructions. Failure to maintain a full charge prior to

and during storage can result in permanent damage to the Li Expander Pak 2400s.

3. If one or more Li Expander Paks displays a Blinking RED Battery Status LED, please refer

to Technical Bulletin 1B.
