— WHY EDICELL
Why
edicell
The FPV battery market has a spec problem. Inflated C ratings, unknown cells, capacity that doesn't match the label. We got tired of it too.
Every cell is disclosed.
UN38.3 certified.
SDS published.
Spec sheet available before you buy.
Grade A tabless cells only.
Real discharge ratings.
Over a decade of lithium expertise.
— CELL TECHNOLOGY
The tab is
the weak point.
Traditional 21700 cells use a small metal tab to connect the electrode to the terminal. One tab carrying all the current means heat buildup, voltage sag under load, and a structural weak point that degrades with every cycle.
The Reliance RS50 is tabless. The entire electrode edge becomes the current path. Lower resistance. Even heat distribution. Stable voltage whether you're cruising at 10A or pulling 70A continuous.
