Hello, I have a problem with my gem delta q charger because I change the 6 batteries of 12V by 3 LiFePO4 of 24V and I try to reprogram the delta q charger with the algorithm #233 and #266 but none of them works and now my computer don’t see the charger on the software ---

This is the type of battery I’m using : ![1733168263717](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/3X/7/7/7716f49293677fdfbe6e36b7a136095f4919323e.jpeg) And this is the model of the charger : ![1733168263697](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/3X/f/2/f24cf834d6f29c7e8394ae8ae47606c59fc85691.jpeg) ---

I am not familiar with this battery. Does it have a BMS that monitor/protect the battery? Tip- Whenever you install a pack as 3 separate cells, it is best to charge them as such, NOT as a single unit. I don’t think using the DQ is a good idea in this case. There is no way the DQ can be set up to be aware of the 3 different batteries in your pack. Did these 24v batteries come with a designated charger? In which, you would wire up 3 chargers(one per battery). ---

> [@AssyRequired](#): > > Does it have a BMS that monitor/protect the battery? the datasheet say : The PowerBrick 24V-150Ah integrates an innovative control system (BMS) into its housing to ensure a very high level of safety during use. The BMS constantly controls and balances the battery cells, in order to protect the battery and increase its lifespan. The BMS also protects the battery from any mishandling: deep discharge, excessively high charging voltage, etc. > [@AssyRequired](#): > > Did these 24v batteries come with a designated charger?

That ship has sailed. You have two 24v batteries, now. They may or may not work at 48v, but they will need 24v charging. ---

Going beyond the scope of what original factory intended or installed takes a bit of engineering and understanding that most users do not appreciate. Do it right, and all will be good. Do it wrong, and you will be doing it all over again. Building a special pack is not easy. This is not something you can do by ordering random items and dropping them in place. Another look at what you have set yourself up for: You have 3) 24v batteries. All of them need their own dedicated 24v charger for this to work. Unfortunately, your onboard battery meter will no longer be accurate. Reason: If each battery has it’s own BMS, that is good. The problem is that these 3 individual BMS units do not communicate with each other or with the charger. They were intended to be installed as individual components in a 24v vehicle. Explain: As you know, in your GEM, you need to install these 3 batteries in series config to get to 72v operating voltage. These batteries do not see **how** they are hooked up, nor do they care of anything past their own case. When in series, there is a good chance one will eventually get out of balance with the other two. Sure, the pack(as a whole) will work for a while, but when charged up in series (the DQ will charge them as a group), the first one that reaches it’s high limit will shut down the charge cycle. The other two will never finish the charge cycle. Expanding further, you then take the car out after a truncated charge cycle and the first battery to reach the low battery level will shut down the output power to protect itself (BMS is doing it’s job). You may not even notice this happening. Eventually, your low battery will not even charge. This is why I suggest each having a dedicated 24v charger for each battery. Make sure it is certified for LPO(LiFePo4). ---

And there are no charger that can be buy which is compatible with the gem and the lithium batteries LiFePO4 ? ---

Will you let us know how that works out.? Everyone I have talked to said I can’t cause the bms conflict. Everyone I talked to said no more that four 12s or two 24s… Thanks. ---

I don’t think it’s the chargers as mu much as it is the bms s . In the batts. Possibly it might be doable by stripping out the bms s and replacing them with a bms that will handle all those cells. ---

One charger? Or 3 chargers? Ok. Carry on with your research. I look forward to your report. ---

No but I have the reference of it. It’s the ZIWAN Battery charger NG3 ![IMG_20241217_171722](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/3X/e/a/ea6dc42890993a1efd6059b5321e106521d0c877.jpeg) ---

Anyone I need assistance, 2018 gem E-2 Delta Q #912-4854-05 onboard charger. The (4) LEOCH 6-EV120 AGM 120AH batteries need to be replaced. Polaris dealer/ parts counter little or of no help advising they can’t get them. Representative for LEOCH says he can’t get them ? has anybody on this site replaced the batteries on their 2016-2020 gem ? What has worked for you ? Does anyone know of a replacement battery, what will work with the on board charger as a drop in replacement. I’m located in so. Ca. San Bernardino co. If anyone knows of a battery that will drop in Please let me know. ---

I have one of these, left. 12s 224ah 10kwh 60 mile range. Problem is that complete battery-in-a-box, needs to ship freight.

Left hand battery with bms, shown. Last pictures show it complete, as would ship freight. You might also ask @AssyRequired to deliver one.
