Safe storage and charging: Protect your e-bike’s battery with OptiMate Battery Chargers

OptiMate High Performance Battery Chargers products include innovative smart chargers with user selection for Longer LIFE, More POWER and Sleep mode for safe long-term storage, as well as connectors & intelligent battery monitoring.
Our goal is to provide a very safe, reliable and efficient way for e-bike riders to charge and extend the life of their e-bike battery, whether they are commuting to work or going on a long-distance ride, or placing the bike in storage over winter. Our innovative approach takes the fear out of unsupervised charging and eliminates battery performance issues.
OptiMate wants to partner with e-bike manufacturers and distributors to meet the growing demand for safe un-supervised charging and correct long term care of e-bike batteries.

With the OptiMate charging technology, we focus on mainly 3 types of li-ion batteries:
Lithium Manganese Oxide (LMO), Lithium Cobalt Oxide (LCO) and Lithium Nickel Manganese Cobalt Oxide (NMC), with a nominal voltage per cell of 3.6v-3.7v and with a maximum charging voltage of 4.2v per cell. NMC batteries are the most popular batteries for E-bikes.


Temperature control: why it matters

Lithium batteries can be discharged over a wide temperature range, but it’s not a good idea to charge them at extreme temperatures. Extreme cold and heat reduce the acceptance of charge. Best battery performance range is between 10°C and 30°C, with the ideal charging range between 0°C and 40°C.

– 20°C and lower: no charge

– 20°C till – 10°C: charge at 25% current

– 10°C till 0°C: charge at 50% current

0°C till 40°C: charge at 100% current

40°C till 50°C: charge at 50% current

50°C till 55°C: charge at 25% current

55°C and more: no charge

OptiMate innovative smart chargers come with advanced features to safely recover batteries with less than 40% charge. Safety during charging is key, to prevent your battery from overcharging or undercharging. Both will damage your battery and shorten its lifespan.


OptiMate also offers a range of connectors and adaptor cables to fit your e-bike battery.

A safety monitor that can be mounted between the battery and any battery charger, can monitor the battery charge at any time. If a damaged cell is detected, the charger will automatically stop charging to prevent overheating or further damage to your battery. With these safety features, you can trust OptiMate to keep your electric bike battery safe and in excellent condition.

In summary, if you want to ensure the safety and longevity of your Lithium-Ion battery for your electric bicycle, then you have come to the right place at OptiMate! With their advanced features, safety features, and rigorous testing, OptiMate battery chargers are the smart choice for any electric bicycle owner looking to get the most out of their investment.
