These have a true 400mAh capacity. I tested them with a pro-level charger/discharger, discharged to 3.0v at 2.5C (1.0A). They work well with my Walkera Lama 2 and give the same flight time as the original OEM battery that came with it, about 8-9 minutes.
They don't appear to be real Walkera batteries, whereas the 500s and 600s that are also available here do.
They fit slightly looser in the battery holder, so after a minor crash, you have to make sure it is all the way forward again for the weight balance, but this is a minor complaint.
Even as a set of 3, they are more expensive than the 500s or 600s.
For some reason, at all other sites I looked for these, they all seemed to be out of stock. I got a set of 3 of them from here in a little over a week. Nice!
Recommended replacement, true capacity battery that work well for intended purpose. Not exactly cheap, but certainly reasonable price, especially with included shipping, which is fast.
