FreedConn BM2-S BM12 Motorcycle Bluetooth Helmet Upgrade to Bluetooth 5.0 Since April, 2023 - Battery & Chip

The battery needs to be in the helmet to be charged. Will not work if you charge battery only.

I have a motorcycle helmet that has Bluetooth built into it. I had a battery so this one came with it and it broke after a few years charger part broke, but I bought this one. I never really liked the price of batteries like this, but this is good little better than usual, but anyway, it works perfectly in my helmet. I’d like about these batteries is part of it is it tells you what the battery power is at each time you turn on the helmet and I can get long amount of time with this of course eventually has to be charged, but it charges quickly , and you can get out of it. I usually ride my bike from 20 minutes to half an hour every day and I still get plenty of time out of Valerie.

It was different from the original battery that I had to replace with this one, because some of the features of the helmet didn't work.

Looks good works as advertised.

Works great, holds a good long charge.

I have bought 2 replacements and EVERY TIME the plug end to the battery has detached and gone into the battery case!!! Talk about FRUSTRATING and for the COST of this piece of JUNK is ridiculous!!! Jw

Battery arrived the next day, I charged it up and tested the Bluetooth, it works fine.

Battery works with my ilm 953 helmet. Though, my helmet now speaks Chinese and won't pair with another ilm helmet.
