The Meepo Classic is sold with either a standard 4Ah 10s2p pack (Samsung 20R, 18650) or an upgraded 8Ah pack (Sanyo 20700). I want to see if I can put together a pack myself that is at least as good as the Sanyo pack. Now I need to decide on
- What cells to use
- 10s2p or 10s3p
- what BMS to use
I find it difficult to decide on a cell type because I know next to nothing about the hobbywing ESC on the board. The motors are rated at a combined 800W. That should mean I need to supply less that 25A under full load with an empty 10s pack. That number already limits my options for 2p builds. However I cannot find any info on the cutoff voltage of the ESC. My main candidates for cells are
- Sanyo NCR20700B (4250mAh, 15A discharge) (same as upgraded pack from meepo)
- Samsung INR21700-50E (5000mAh, 10A discharge)
If the cutoff voltage is too high, then the Samsung cell would loose most of its capacity advantage.
So my main question at the moment is: does anyone know at what voltage the meepo hobbywing ESC stops discharging? Other cells I should consider? BMS suggestions?
