![]() For example: when you want a 12V battery with a capacity of 200Ah and you want to build this from 100Ah cells (3.3V), then configure the battery as 2P4S. The capacity of a string of cells parallel is the sum of the indivual capacities. This means that you do not have to monitor each cell in parallel, but only the voltage of the whole parallel branch. The voltage on each cell is always the same. The big advantage of cells parallel is that the cells keep each other balanced. Each situation has advantages and disadvantages and, of course, things to look out for. To increase capacity, multiple cells can be connected in parallel or you can place multiple battery banks in parallel. For example, because you want to increase the capacity of an existing battery, or perhaps because the desired cell capacity is not available in one battery package. Better performance and less overall stress on each battery.Placing multiple battery banks or cells in parallel increases capacity. 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. 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. ![]() 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. Posted by Melvin Belcher on Feb 26th 2023 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. ![]() The black box itself is really small so I was able to place it right inside where water makes no contact. My ebike has its controller and connections inside the downtube. I most of the time didn't even bother bringing my second battery on these days. This was a major issue for me when it rained. No more more stopping to unscrew and disconnect and reconnect. This connector is amazing and definitely solved my problem. That way I would have ordered the adapters and be happy dappy with my 2 batteries. It should be mentioned in the description of the product. I have a 52v 37.5 amp ebike.ĭoes this connect to radpower bikes straight out of the box, or do i have to change connecters?īe aware that the plugs are xt90, I have ordered adapters so they will fit my xt60 plugs. This is much better battery management for me. I wasn't sure because it was easy enough to connect and disconnect, but no. I love having these batteries in parallel. 120 mile range with an average speed of 17 mph. 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?Ģ019 Radrover: 52v 17.5 amp and 52v 20 amp. Posted by Steven Courtnage on Feb 26th 2023 I can not thank you enough for your explanations and demonstrated knowledge of e-bikes which makes you my "Go to You-Tube Guy". Great job and your informational videos has helped me in so many ways. This device has doubled my biking distance to over 70+ miles one way with peddle assist mode. I was watching one of your video about battery upgrades as a option to increase my biking distance and (Eureka!!!) You just blurted out a way to easily combine them into the solution to my challenge with the dual battery parallel connector. I was racking my brain trying to come up with a way to use both of my 48 volt batteries in order to extend my travel time while bike backpack camping within 75 miles of my home.
