10s 42V 6 Amp Fast Charger. Works with 10s battery packs!
For best use:
Plug the charger into the bike BEFORE plugging it into the wall. This helps prevent early plug degradation due to the charging arc.
Using ANY fast charger on any battery WILL degrade your battery quicker. To prolong the usable life of your battery, you should try to avoid using this charger as your main charger. This charger is best used when you are on the go and you should use your stock charger when charge time is not important. This charger will decrease charge time but lengthen cell balancing time, which accounts for the last few percent. Meaning, once you reach ~95%, it is normal for the charger to slow down.
