NiMH Upgrade

Sorry, we don't do the NIMH batteries anymore. However if you choose to upgrade to a Li-Ion battery you will get a smaller more powerful battery that will burn your lights brighter and last longer. You will also qualify for the Li- Ion charger at half price. Just email or phone in your details to prove you have a original NiMH system and we will give you a promo code for £20 off from the charger price.

Li-Ion batteries weren't around when we started selling the NiMH batteries so unfortunately a NiMH charger wont work with a Li-Ion battery.

For comparison the NiMH 4.0 Amp/H 12 volt batteries had a capacity of 48 Watt/ Hours if they were the earliest 1997-1999 batteries, they weighed approx 650g. From 2000 onwards the NiMH batteries ran at 13.2 volts and so their capacity increased to 52 watt/ Hours, they weighed approx 700g.

The Elite 2.6 Amp/H , 14.8 v Li-Ion battery has a capacity of 38 Watt/ Hours and weighs 260g. The Pro 5.2 Amp/Hour 14.8 v Li- Ion battery has a capacity of 76 Watt/ Hours and weighs approx 500g.
