A part of the review has been auto-translated.
well composed and packed, arrived in good condition. Briefly tried the battery with a electric boat motor, works, but need to charge first. Voltage was 13.2V when arrived. Unfortunately there is no manual how to charge battery, car charger can go up to 15V, for battery the maximum is 14.6V.
Delivery from CZ warehouse took twice as long as usual, I waited. I immediately connected the battery to a small balcony solar system works as expected, I haven't verified the capacity yet, but from experience it is about 40 Ah.
