To counter this, your batteries should be wired with "Balanced Charging" in mind, which basically means that the total number of leads that separate your battery from the charger is equal for each battery. Figure 1 - Unbalanced Charging A common, yet inefficient way of charging batteries in parallel. Figure 2 - Unbalanced Charging
@Stephen Walker that would mean that it most likely your battery cells. You''d have to take the pack apart and check the cells. Now here is the downside. Some of those packs have an IC that prevents the battery from charging if their charge cycle count to high etc. Just another manufacturers gimmick from repairing the battery.
Charging an 18v battery without a dedicated charger is indeed possible, thanks to alternative methods and DIY solutions. Whether you choose to use a power supply, harness solar energy, leverage USB charging, tap into a …
I have a 12Ah 18v Milwaukee RedLithium pack which has become unbalanced. The pack charges via the milwaukee charger to "completion", but while using the battery it …
You''re right about the third vertical contact point. It''s directly connected to the negative end of the pack (pin #1 on my above picture). The voltage difference between it and pin#1 is zero when the battery is at rest, and some mVs when the battery is discharging. So we now know that the charging points are the same as the discharging points.
Thanks Phill, the 7812 is for supplying 12V to the IC 741, it''s not for the battery. Because a 741 won''t tolerate over 18V. The input should be around 21/22V for charging a 18V battery. 0.3 A will be fine for a 1.5 Ah battery, just make sure the battery does not get warm during charging, otherwise you may have reduce the current.
Experimental temperature variation in battery pack with unbalanced SOCs during charging process Abstract: The State of Charge (SOC) inconsistency is common for battery pack after long-term cycling. The unbalanced SOCs is a …
