HI i have lii 500 charger
i just opened some used makita packs and kept the ones over 2.5v right of the bat.
on lii 500 i see there are nortest, charge and test mode
wich do i use if i want to build a battery ebike
why nor test over just charge? or vice versa
it seems i have to select discharge 250 or 500 ma
and choose charging 500ma or 750 or 1000ma
will the charger stop by it self of i need to check it often after x minutes x hours

Note: Sony VTC4 IMR cells have a much lower internal resistance than regular 3.7V lithium ions. Voltage could go higher when charged on certain chargers such as the older versions of the WF-139 charger. Always check the voltage of your 18650 IMR battery after a full charge to make sure it is above 4.2V. You can use a multimeter to do this. Overcharging your Sony VTC4 above 4.25V may shorten the life cycle or even cause permanent damage to the product.
Do not over-discharge or over-charge your battery.
Recharge empty batteries (resting voltage of 3.6V) as soon as possible. Batteries that are fully drained and left in a discharged state for a long time could result in irreversible damage.
Do not short circuit to prevent massive release of current.
Do not dispose in fire.
Do not leave unattended inside a vehicle.
Do not store or carry your batteries in your pocket, purse or anywhere they can make contact with other metal objects.
Do not leave unattended while charging.
Discontinue use if the battery looks worn, torn, or is exhibiting unusual behavior.
