They are also, conveniently, closer to the 5v needed for USB power, so you don't have to regulate down as much. LiFePO4 batteries offer advantages over LiPo batteries in that they are more stable, can stay charged for long periods without damage, can hold a charge longer than LiPos, can discharge further below the average cell voltage without damage, and have a flatter discharge curve. The batteries are 6.6 v 1100 mAh LiFePO4 (Lithium Iron Phosphate) 2S (2 cells in series) 10C discharge (10x battery capacity) R/C receiver batteries from HobbyKing or Amazon. For the hacking side of things, I leave that up to the end user, but there is a link to the Pentura Labs page which explains how to load the Pineapple scripts and config files, etc. If you want a more user-friendly router interface, DD-WRT supports this router as well. In terms of software, OpenWRT is the OS of choice for maximum hackability. I am planning on/ have replaced that with an external antenna RP-SMA connector, as shown on the router's OpenWRT Page. The built in antenna is a 1/4 wave F-shaped antenna, printed on the PCB. It uses 0.5W on average, giving it a 58 hour runtime with the 4.4 Ah of batteries ((4.4 Ah * 6.6 v)/0.5 W = 58 hrs). It has an on board USB port, an Ethernet port, and a micro USB port for power. ![]() The TL-MR3020 router is an English version of the TL-WL702N router.
