Is there harm to the battery charging and discharging at the same time? No... In fact, if you think about it, you likely do something similar daily with tablets, laptops, phones, etc. This is further proven via the numerous portable radio stops that are supplemented with solar charging, which charge the battery via a charge controller while the operator is using it. Does constant charging (while driving) lessens the life of the battery? With a proper charger, this wouldn't be the case. Once the battery is fully charged, it would then cease trying to charge it further... The battery's BMS also tends to protect it, as well. FYI, this is the charger I use... simple, but effective Also, what battery are you using? I've been using a 30Ah CYCLENBATT off Amazon, though it doesn't appeared to carried anymore... At least through their Amazon storefront. I also have an ECO-WORTHY 30Ah battery. Neither has given me any issues this far...
