Our Verdict
At 204g, the Silva Free Headlamp Power Battery M 36 Wh adds a useful capacity bump for longer night sessions without moving to the range's heaviest option.
The USB-C power-bank function lets you use the battery to top up a phone or watch, as well as power the headlamp, giving that extra capacity another use on longer trips.
It is compatible with every Free-series headlamp, has a five-level battery indicator and is rated IPX5 for wet-weather use.
For longer winter walks, trail runs or extended night use, the extra capacity makes the M a sensible option.
