Great company, great product. Fred is efficient and competent.
Battery arrived in great shape. Needs M5 x.8 screw for attachment of wires. Battery was deeply discharged to 5.8v I trickle charged with a 1 amp 12v constant current until battery indicated it was at 12V. I waited 2 hours to see if the battery would self discharge indicating damage, but no internal discharging occurred. Then I charged it with a lithium ion charger set to 14.5v @ 5A until it was full. Discharged measured capacity was about 27.2 AH which is close to the stated 28AH. Battery does not have a low voltage cutout, but all the equipment I plan to use it on will not function below 11V so no problem. I do like that the battery can be charged at a 15A rate. Using thermal imaging during charge/ discharge I observed no anomalies / hot cells or hot BMS circuitry, even when charging with 15A rate. Battery working as intended. Pros: inexpensive, functional, smaller than the competition, high discharge rate of 40A, charges fast at 15A rate. Cons: Screws not included for terminals, BMS no low voltage cutout to prevent deep discharge damage.
