Only in one review: Price 25 $ (CSB HRL-1234W-F2-FR).

M18 battery: The case and protection are decent, but capacity is about 4 Ah instead of the claimed 6 Ah; the author advises against buying it.

CSB HRL-1234W-F2-FR: The battery delivered 5.9 Ah and 70 Wh at moderate discharge, but LiFePO4 delivered more energy.
