Lithium Ion batteries... loose the weight not the juice...
All energy packed in storage presents some risk and Lithium-ion batteries
have about seven times the energy density of traditional lead-acid
batteries, which means you can get much more power from a much
smaller-and lighter-battery pack. As with any new, unfamiliar
technologies, lithium~ion batteries have spawned various alarmist
views but used properly, they're superior to their old lead-acid
predecessors.
For owners of performance oriented machines installing a Lithium
batteries is the cheapest quickest and easiest way to shed unwanted
weight but I’ve noticed they're not for everybody... especially some
of my customer who close their wallet with a torque wench...
I've been using Lithium Ion batteries since 2009... First was the
(SpeedCell) since sold to a customer... currently Mr.RC45 is powered
by a Shoria... I think days of the old heavy lead acid battery are
number... smart money is on the new light weight Lithium Ion
battery...
