This battery tray is the same tried and tested tray we have offered for the last few year. The big difference as you can see we integrated a mount for the new ic3 device connector. It allows you to install the connector without removing and adding a new connector. This will be available in pulse 2550,3600, & 5000 mah sizes. Depending on the popularity we could do more sizes and as always don’t hesitate to send a email about getting them custom made to your needs.
