Love these VMax AGM batteries
Sorry for delayed response but didn't see this. We replaced the original 5 yo SLA batteries in our 2014 EV for the above referenced ones 6 months ago but did have trouble changing the DeltaQ charger algorithms. Sent the charger to Boilermkr and he reprogrammed the charger and the system works perfectly. The EV now has much improved power. Since we don't use it for long distance work can't give feedback on range, but can say we go up and down hills and it performs well. The battery indicator rarely drops below 98%. And with no maintenance required, we're very glad we made the change.
P.S. We didn't install a temperature sensor for the new batteries and have had no problems.
