Sure. While we wait for someone (cough, cough) to post some NV videos;
The batteries are LiFePO4, 25 amp hour.
Rated at 1C charge, 3C discharge, 5C burst (10 sec).
Contact posts are 6mm x 1mm.
4 wired in series.
The BMS is 4S, 30 amp.
Both from BatteryHookup.com
The pack is not as compact as a Li-ion/LiPo pack but is "safer" and the output voltage is flatter across the discharge range. Each pack weighs about
6 pounds.
I charge with a ToolKitRC M6D running off a Xbox 200watt supply. Everything but the X-Box supply was bought new. Got 3 of them CHEAP, opened, cleaned fans, and great supply for the size.
Connectors are XT60.
Here is a pic of the wiring (CLICK FOR LARGE VIEW). Notice different orientation of cells between the two packs.
Can't see it in the pic but each cell has a plastic spacer between the cells to isolate the cell case.
From the BatteryHookup website;
Ran one last night with the IR light (photocell on to photocell off). Resting voltage this morning was 3.285 for each cell (all within one millivolt).
