This voltage for a lithium battery is way too low. At this voltage, the lithium battery will have been depleted to approx 10-15% state of charge. Lithium charge algorithms will normally set a return to the bulk voltage of 13.1-13.2V. Just another reason that a standard lead-acid charger doesn’t suit lithium batteries.
For safe charging of a 3.7 V Lithium-ion batteries, they should be charged at constant-current of 0.2 to 0.7 times their capacity, till their terminal voltage reach 4.2 V, later they should be charged in constant-voltage mode till charging current drops to 10% of initial charging rate.
This Lithium Battery USB Charger Module support charging the battery, simply supply a 5V Micro-USB source to the charging input and it will charge the connected battery to 4.2V. Great for mobile power source using Lithium ion batteries (unprotected is also ok). Connect multiple batteries to the battery input to increase the capacity power capacity.
