FAQ about LED bike light

Q1. What is the difference between the MJ-6038 default battery pack and MJ-828 Battery pack ?

A1: The battery cells are the same for both MJ-6038 default and MJ-828 Battery.  Both use BAK (NASDAQ: CBAK) 18650 Li-ion rechargeable batteries. For 4-cell battery pack, the total capacity is 4400 mAh if the pack is fully charged. The main difference between the two is packaging. Default battery pack normally has a rubber enclosure and a hard battery case with  2 straps. While MJ-828 Battery is packaged in a aluminum case and a strap. For this reason, MJ-828 looks larger and is heavier than MJ-6038 default battery pack. The other difference is that the MJ-828 Battery pack has a small LCD display on the top, which shows the remaining capacity and voltage of the pack.  Both battery packs have the same waterproof level IPX7.

 

Q2: Is there better and more capacity battery from MagicShine?

A2:  Yes, MagicShine supplies 5600 mAh SAMSUNG 4 cells battery pack and 6600 mAh BAK 6 cell battery pack, which could be used for MJ-808(E,U)/MJ-872/MJ-856(B)/MJ-868/MJ-816(E,U)/MJ-818 bike lights. However, the battery pack are more expensive than MJ-6002 default battery pack.
