Thanks to the use of Lithium Iron Phosphate (LiFePO4) as a positive pole material and graphite (C) as negative pole material, SHIDO Li-ion Batteries offer the best quality both technology and performance wise. 

Very lighweight, waterproof and powerful, SHIDO Batteries ensure a higher intensity during startup compared to a regular lead-acid battery. Lifetime is also 3 to 4 times longer than a regular battery.

SHIDO Li-ion batteries are way more powerful than regular batteries thanks to a 5 times more concentrated power output and 3 times more important maximum unloading capacity.

This high unloading capacity is a strength for motorsport applications and the need for high output batteries. 

Li-ion batteries offer stable capacities up to 4 times longer than regular ones, ensuring for the best lifetime even when not in use and stored.

Compatible with race cars, motorbikes, ATV and even Jet-ski !

SHIDO Li-ion batteries offer multiple advantages :

Ultimate starting capabilities

3/4 lighter than a regular battery

Maximum unloading capacity

3 to 4 times longer lifetime than a regular lead battery

Lower consumption

Ultra fast charge

No risk of explosion

No maintenance

Stable charging tension

No pollution

Capacity indicator

Waterproof

Multiple position installation

Battery charge : It is mandatory to never charge this battery at a higher voltage than 15V. Never install a lithium battery if the trickle charger can go higher than a 15V tension. Battery needs to be charged before first use.

WARNING : lithium batteries have a specific charging process. Most alternators have a high output than can damage the battery. Lithium battery use requires an adaptation of the entire car's electric system with the replacement of the alternator or the use of a BMS.

GT2i Team advice : Don't forget SHIDO's specific battery charger sold separately : SHI-CHARGEUR

The OptiMate 2 DUO battery charger is designed for 12V AGM, GEL, EFB, lead-acid, and LiFePO4 lithium batteries. It automatically charges, diagnoses, and maintains the battery’s charge to preserve its performance, whether the vehicle is used regularly or remains stationary for long periods.
Thanks to its DUO technology, the battery charger automatically detects the type of battery connected and applies the most appropriate charging program without requiring manual selection. Its fully automatic five-stage charging cycle optimizes charging, monitors the battery’s condition, and then switches to trickle charging once the battery is fully charged.
With a 2 A charging current, the OptiMate 2 DUO is suitable for motorcycles, scooters, ATVs, SSVs, jet skis, and other vehicles equipped with batteries ranging from 6 to 96 Ah. It can also recharge deeply discharged batteries starting at 4 V, while alerting the user when a battery is beyond repair or defective.
Designed for unattended use, this charger effectively protects the battery and the vehicle’s electronics thanks to its built-in safeguards against reverse polarity, short circuits, and overcharging. Its weather-resistant housing allows for use in both garages and workshops.
Supplied with a permanent wiring harness featuring eyelet terminals and a set of battery pliers, the OptiMate 2 DUO can be quickly installed on most compatible vehicles. Once connected, it automatically provides trickle charging to ensure the battery is always ready to start the engine, while helping to extend its service life.
