Battery Connection

• Single Battery
• Multiple Batteries
!
Caution
• Before use, check if the voltage difference between the batteries is less than 0.1 VDC before
using them in series connection, or less than 0.5 VDC in parallel connection. If not, charge the
batteries separately, and float charge them for 24 hours after a full charge. Otherwise,
over-current protection may be triggered due to the large voltage difference.
• Do not mix batteries of different brands, types, models or life spans.
• In order to prolong the life span of the batteries, please make sure the length, diameter and
internal resistance of the power cables are the same when using multiple batteries.
Safety Goggles
• Cut off the power before wiring, installing or removing the
battery.
• To prevent electric shock, please remove watches, brace-
lets, rings and other conductive items (if any) and wear
insulating gloves and safety goggles before installation.
