A couple of questions concerning voltage testing batteries with a DC voltmeter. I will be testing eight series-connected 6-volt batteries in a 48Volt Bad Boy Buggy.
Do I need to unhook any battery cables? If so, which ones?
Can I use a DC voltmeter across the entire pack? As in the start and end of the series connection- the negative and positive posts (B+ and B-) that go to the charger?
Or, do I need to unhook each battery from its downstream and upstream neighbor and test it individually?
Is testing specific gravity with a hydrometer "better" than the DC voltmeter? It seems like it would take a lot more time.
Thank you.
