- Not as powerful as I expected. Review by Pontus

Just tried to use those cells as an alternative to LiPo pouch cells. My application is a 3m aerobatic RC-plane.Rating
Pack of 12s5p (20 Ah 43,2 V).
I had calculated a burst power (10 seconds) of some 220 A at 40 to 41 V under load. That’s just 11 C. Quite disappointed to read only 175 Amps at 38 V at about 85% SOC. Only 6,6 kW output from a 4,2 kg battery. And very rapid heating of the pack too. By calculation, I find the cell iR to be in the region of at least 20 mOhm. Much worse than expected. Typical for a LiPo cell of similar weight is between 4 to 7 mOhm. I put 3 stars as I think those cells are still good for less peak-power requirements.

Take care
- Li-ion batteries can be dangerous when used wrong, short circuit or wrong usage can lead to fire or an explosion
- Do not put the battery in a charger or equipment with wrong terminals connected
- Never short cut the battery. Take care you don’t short cut it accidentally, do not put it in your pocked together with bunch of keys
- Do not disassemble or deform the battery. Dispose it if the battery is deformed
- Do not immerse in water
- Avoid excessive physical shock or vibration
- Do not expose to, dispose of the battery in fire
- Keep out of the reach of children
- Never use a modified or damaged charger
- Do not leave battery in charger over 12 hours
- Store the battery in a cool, dry and well-ventilated area
- Dispose of in accordance with local regulations
- Do not solder on these cells
