Dual Battery Parallel connector

Works great! But once your batteries are connected with this adaptor, can they be charged as one battery? Or should i disconnect and charge them?

2019 Radrover: 52v 17.5 amp and 52v 20 amp. 120 mile range with an average speed of 17 mph. I love having these batteries in parallel. I wasn't sure because it was easy enough to connect and disconnect, but no. This is much better battery management for me. I have a 52v 37.5 amp ebike.

Does this connect to radpower bikes straight out of the box, or do i have to change connecters?

Be aware that the plugs are xt90, I have ordered adapters so they will fit my xt60 plugs. It should be mentioned in the description of the product. That way I would have ordered the adapters and be happy dappy with my 2 batteries.

This connector is amazing and definitely solved my problem. No more more stopping to unscrew and disconnect and reconnect. This was a major issue for me when it rained. I most of the time didn't even bother bringing my second battery on these days. My ebike has its controller and connections inside the downtube. The black box itself is really small so I was able to place it right inside where water makes no contact. I can choose which battery I want to use first or just use them both at the same time all without ever having to disconnect. Amazing product well worth it. 48v 26ah + 48v 21ah .

You are someone who really cares. Thanks for your time.

Works well and pretty much as advertised, but I have one small issue of having to flip the power rocker on the second connected battery a few times to make sure the controller picks it up. If I don't do this or forget to, I will end up riding with one battery and don't notice until half way through when I have half the charge I expect. Other than that it works well and gives me about 80-100 Miles range mostly electric with my two 19.2Ah batteries, which is actually about 10-15 Miles more than draining one, then switching and draining the other. Better performance and less overall stress on each battery.

This is a must have! It makes any bike more practical. It allows me to use my stock battery with any battery I can afford at the moment. The adapter is easy to use and made exceptionally well.

Using two 48v batteries one 10ah and one 14ah. One is high quality LG cells, the other generic from China. Both batteries have BMS limit of 20amps. Device works well, can leave everything hooked up, can charge each battery with separate chargers while all hooked up. Device has stayed cool to the touch while riding.
