So I had the battery pack on charge overnight. Been getting just over 48v at the main terminals with no load. Lifting the forks slowly drops the voltage to 38-40v. Now I've checked each 2v unit (with no load) and 14 are a touch above 2v - say 2.03 and the remainng 10 are at 1.93v-1.97v. What is weird though is that I know the charger has been kicking on and off overnight and shows green in the morning (It then performed these tests) but the gauge on the forklift was orange/half way adn then just now red/very low even though the forklift as just raised the mast slowly a couple of times. no real work to load/drain the batteries in such a short timeframe. Can their be a massive drain on the batteries? Is this an indication they're knackered? Should I see what the voltage drops to on each 2v unit so see if any inparticular drop very low? Cheers
