OPzV batteries are tubular batteries, they are 2V and large capacity cells, you need to put them in series for a power supply of 12, 24, 48V.
OPzV are waterproof, their use remains more or less the same, they are easy-to-use batteries with the best durability taking into account the price.
They accept a discharge rate of 80% and easily withstand high current demands and fast recharges. They also maintain the proper capacity in both heat and cold, however their durability will still be affected.
Their elongated shape will force you to store them in the safe if stored in areas subject to shocks (boats, campers, trucks).
These batteries are suitable for large electricity and autonomy needs.
