Testing shows a capacity of our battery pack around 3.20Ah or 33.77Wh.
Question: Can we safely charge this with our 14.6v 20A Charger?
Answer: No, charger toggles between charge and standby and battery shows 13+ volts.
Perhaps we can add a voltage regulator with the output set to about 12v?

Question: Can we safely charge this with our 14.6v 20A Charger?
Answer: No, charger toggles between charge and standby and battery shows 13+ volts. The BMS is disconnecting and reconnecting because the voltage is too high.
Perhaps we can add a voltage regulator with the output set to about 12v?
