Magicshine's MJ-6116 battery pack is a 5200mAh 7.2V replacement rechargeable battery pack for your MagicshineMJ-900 series, MJ-902 series and MJ-906 series bike lights as well as the Monteer 3500S. The clever thing is, that it's also a portable power source that provides you with a USB outlet for recharging your phone or GPS device while out on the trail.

You can recharge the MJ-6116 using any typical USB AC wall charger and the included cable via the Micro USB input. If you just want to take the battery with you as a USB power supply, you can remove the battery cable from the battery and replace it with a silicone dust cover.

With a built-in battery monitor and check button, you'll always know how much power you have left and with an IXP4 rating (protected against splashing water from any angle) you don't have to be concerned about getting caught in the rain.

Power is provided by 4 x 18650 Lithium-Ion cells and the whole package is just 170x37x39mm in size and weighs 365g. The MJ-6116 has a soft, non-slip silicone foam strip on one side and is supplied with a Nylon and Velcro strap for you to secure the battery to your frame without damage or movement.

All Magicshine batteries have a wide operating and discharge range and include a circuit with over-charge, over-discharge and short circuit protection meaning you can be sure that your Magicshine battery is safe to use and charge.

This battery is not compatible with Monteer 6500S/8000S/8000S V2.
