I only have a charger for 2 batteries at a time. My thought was to place the 3 18650's in the flashlight and charge them using the rechargeable micro USB cable...
will this have any negative impact on light, batteries etc?
Do you mean 2 bay independent charger?I only have a charger for 2 batteries at a time.
Charging 3 of unprotected li-ion in series is not recommended and best way is recharge individually.My thought was to place the 3 18650's in the flashlight and charge them using the rechargeable micro USB cable...
Not all batteries remain same like new during years and one may loose capacity more than other. In this case, good one will reverse charge the other cell which is bad for both cells.will this have any negative impact on light, batteries etc?
