Charger: powerlab 6, ordered at Lhs and purchased about 3 months ago
Power supply: 2xhp server supplies in series, 24.8v, 1100 watts total
Can charge combinations of 3s to 6s without issue, charge rates vary from 5a to 35a.
When charging small batteries, specifically 2s300 x 3 lipo parallel at 2c, or 600ma per pack, 1.8a total, or a 6s1700 NiMH at 2a or less, I get safety code 96 a few minutes into charge. When charging the NiMH, it will sometimes false peak and go to trickle in just a few minutes.
