I've been using this battery balancer device for a few months and noticed two benefits. 1. It allowed me to get a longer range than manually swapping one battery out for the spare during the ride. 2. Since both batteries output lower currents, it puts less strain on each which may increase battery life. Note: Both batteries must be at the same voltage level, the AH ratings can be different. Initially, when you start, the battery with the slightly highest voltage will supply all the current to the motor, when its voltage drops to the level of the second battery, they will both start sharing half the total current demand. Two connected batteries share the amount of current needed by the motor and keep the two batteries at the same voltage level as they start to decrease during the ride.

My biggest concern is volt matching. Some say the batteries must match volts…others say it doesn’t matter. The pro-match say that pairing a higher voltage battery with a lower voltage battery with cause the higher voltage one to discharge too quickly and lead to a dangerous situation…like explosions etc. That’s enough to make me wanna be very sure before moving forward. The E-Bike I have has an integrated battery that slides into the frame. The LED screen reads 52v output when fully charged. But, the description on Amazon says it’s a 48v 15Ah battery. So…now I find myself in a dilemma. What’s the true voltage rating on my battery and how critical is it to have the same voltage batteries with this battery coupling gadget?

If you mixed the two, with two fully charged batteries the 52v would be around halfway discharged before the 48v even started contributing, and depending on the BMS of the 52v would go below safe voltages before the 48v was getting close to being discharged. Even if everything went smoothly you wouldn't be getting the benefit of these devices which is mainly the lower amperage draw from each battery, keeping them cooler and lasting longer, both for each ride and in lifespan.

​@gotchurebeacons-gaming9023 If you have a 48v battery, 48 volts is the 'nominal' voltage or middle of the range of voltages for that battery. When you charge a 48v battery, it actually charges to 54.6 volts, and when it is empty, it will be somewhere around 40-41 volts, and bike will stop working.

OMG!!! Found your channel while I was in the midst of my “gas bike phase” and found your content helpful and it got me considering an electric option. Fast forward a year and an accident on the gas bike later and I’m now a proud E-Bike rider…and loving the ability to ride on trails instead of sharing the roads with motorists. My biggest gripe was the short rages of the batteries and I’ve been looking for a trusted source with advice about these battery blenders…and GUESS WHO pops into my YT suggestions with a new video?!?! Creepy-good timing? Perhaps…but I’m thankful nonetheless 😊

If you have both batteries for sure with 2 wire BMS's you can get versions of these with a charge cable that will charge both batteries at once. Regardless if it has the charge port or not you can't use these with regenerative braking, the same diodes that disallow the batteries to charge each other disallow any charge from the controller.

@@azney-playz9738 it's possible to do regen while using a parallel connection between two batteries, it's just much more potentially dangerous. The batteries have to be at the same voltage, like within millivolts, or the higher one will charge the lower one at as high as amperage as physically possible, if you're lucky it melts the wire before doing too much damage to the batteries. Also best with 2 wire BMS so that once they are connected together you can charge them together and keep them at the same voltage.

@autojohn-pu1vf I wouldn't use a y connector, you could but you will need to make sure your both batteries are at same capacity and voltage when charging or discharging where as for the double battery combiner it doesn't matter if voltage is different, these work by using the high voltage first then when both voltages are the same then it uses both batteries together regardless of capacity and helps with eliminating the voltage dip when using high Amps with one battery

Can I safely use this with a 72a23ah triangle battery and combine it with a 48v20ah rack-type battery or are the different voltages a problem? I'm assuming the reason I'm paying $55 for this thing is because it can deal with the voltage differences or I'd just get a y-adapter for five bucks and combine them in parallel if a same-voltage requirement existed. Then again, I wanna be safe. I'd LOVE to combine these two things for more total amps so my controller or BMS or whatever it is stops cutting out for an hour and rendering my ebike useless when I put it under hard load. I have a 3000w hub motor and my 72a23ah triangle only puts out 1500w and when everything cuts-out I dunno if it's the BMS that did it or my controller but I'm thinking that if I combine these to batteries then I can, possibly, get 1500w from the triangle and another 1000w from the rack-mount one and that-a-way I can crank it up past the "eco" levels into the "standard" levels and not get this cut-out problem. Anyone advise me please?
@ForcingShots
@ForcingShots Жыл бұрын
In your situation, It will not work because 72V(84.0) and 48V(54.6) aren't close to each other in voltage. You can mix 48V(54.6) and 52V(58.8) because they are close to each other when fully charged. The whole point of the battery combiner is when both of them match in voltage, they discharge together until the cutoff voltage. So in other word, you need to get another 72V battery for it to work.

You have a 48v battery, batteries are sold at nominal voltage but peak will be higher as you see. It's normal and nothing to worry about. No one battery will not start discharging in an uncontrolled way unless it doesn't have a BMS. Both batteries should have a BMS the BMS limits the output current. As a rule never use a battery that doesn't have a BMS However you shouldn't use batteries of a different voltage as it defeats the purpose of this device. You should charge them both fully. A slight difference in voltage is ok

Question for you Johnny, I have a Heybike Brawn, two actually, one I was riding got hit by a car. Question is, can I remove the 6 pin battery socket that receives my battery and install it into the system with my current battery? The receptacle has two wires on the smart side, positive and negative. Seems with the second battery plugged into the system along with your combiner would work but I'm new to this stuff. Any answers are appreciated and I enjoy watching your channel. Thanks.

If you use just a splitter you don’t want one battery having more of a draw than the other. Your dealing with two separate bms ‘s. If you had two identical battery packs bought at the same time and charged to the exact same voltage etc. you could probably get away with it. The point of buying a parallel connector is you can add an aux battery and not have to buy another one from the bike manufacturer. Saves a lot of $.

Use a $5 splitter now and spend thousands of dollars later for when the bike eventually catches fire. A Y-splitter does not prevent backflow from the higher voltage pack to the lower. If one battery is more charged than the other, they will rapidly adjust to be at the same potential. That means the battery with the higher voltage will push current into the battery with the lower voltage. The lower voltage battery can be overcharged which can lead to a fire or reduced life cycles for the battery cells.
