5.5 Charging System And Batteries
5.5.1 Charging System - Hybrid
As standard all Niftylifts are fitted with a 18A variable input intelligent charger. The Niftylift can be left on
charge over an infinite period or can be used whilst on charge.
Engine charge or "regen" will charge the batteries at differing rates depending on the mode of operation as
shown in the table below.
Two charge modes can be combined to give 63A maximum current. The Niftylift is designed to allow this
function and will recharge fully discharged batteries quickly to a charged state. If used frequently battery
water levels should be monitored and topped up as required. With regular use of this function as a means
of charging it is essential that regular and thorough maintenance of the batteries is performed.
The engine alternator charges the start battery when the engine is running which keeps the battery at
14.4V. A step-down unit is fitted to all Niftylifts to convert 48V to 14.4V, which provides control system
voltage and keeps the start battery in a charged state. This system also helps keep 48V batteries and the
12V battery in good condition regardless of the operating mode.
Batteries
350 Ah DYNO Batteries are fitted as standard. The Niftylift charger and battery management system are
tuned to provide the best performance with DYNO batteries. If alternative batteries are used the charger
and battery management system must be reconfigured to suit the replacement batteries. Contact Niftylift
for further information.
