Daniels offers two battery backup cases to provide additional battery backup to that offered in the case (ET-4 and ET-5). Shown below left is a 35 AH external battery with interconnect cable that is available for all transportable cases. This allows approximately 36 hours of operation.

For higher current drain applications (ET-1) or longer battery backup, Daniels has also developed a 100 AH external battery kit as shown above right that interconnects to all transportable cases. This allows approximately 110 hours of operation. The 100 AH battery kit includes protective circuit breakers and a bus bar. As shown on the next page the Daniels battery design enables parallel batteries and solar panels for longer operation.
