Description
Height is the first thing to check with the Leoch LDC6-400-L16. The case rises 15.98 inches and reaches 16.85 inches over the terminals, all on a footprint of just 11.61 by 7.09 inches. That tall, narrow shape is what holds 400Ah at the 20-hour rate, the largest figure among the 6V LDC models, so confirm your battery tray or compartment has the vertical clearance before anything else.
The rate figures hold up well for a battery this size: 342Ah over 5 hours, 310Ah over 3 hours, and reserve capacity of 925 minutes at 25A and 265 minutes at 75A. Wired in series, six give you a 36V string and eight a 48V string, so the bank's total weight is worth working out in advance. Each unit is 119.5 lbs, which makes this a two-person lift and a poor candidate for anyone replacing batteries by hand on a regular schedule.
The neighbouring LDC6-350 uses the same 295 by 180 mm footprint but stands 60 mm lower. Choosing the 400 over it adds 50Ah at the 20-hour rate and 37Ah at the 5-hour rate for an extra 6 kg, provided the extra height is available.
