I came into a hand-held marine VHS receiver that seems to be fine except the LIPO battery is completely drained, and the circuit board in its charging station badly corroded (and product has been discontinued). I'm trying to figure out if it's worth it to build a replacement charger.
The specs on the battery pack are 7.4v with 1400mAh capacity. So obviously that's 2 cells. There are 3 contacts from the LIPO to the charging station but they are not labeled.
All of the tutorials and modules I've seen for LIPO chargers are for single 3.7v cells. What reading I've done on charging multi-cells suggest the charging is more complicated, and my knowledge of battery chemistry is pretty limited.
Grateful for any thoughts or information on how to proceed. For starters: can/should I hook up an ordinary 3.7v charger and will that have any effect, or is this a stupid/unsafe idea?
