No, that’s what I’m getting - but original Discover batts never even got to 400a. 2 kids, 2 adults…it’s a squeeze but it’s only for about 5 mins from water to top of island we live on.

Can’t speak for others but the Allion batts were straight swap, everything worked. Had to make a couple of longer leads, and since changed DeltaQ to Lithium profile, but essentially a drop-in system. About three hours all up. Amazing performance now and getting 400a draw on dash meter when up very steep hill with four people in, so finally using the systems full potential. Very happy.

We have no fuel near us, so EV only option. Now a hybrid buggy would be good, best of both worlds until batt tech doubles in capacity...

Ok, so after the new LifePo4's are in, the one wild card i though might crop up, has. Before was dumb batteries with a smart buggy system. Now its smart batteries 'talking' to a smart buggy. If i have the new batts at 100%, when we leave our property we have a very steep hill for 100m's. The regen is trying to feed the full batts, but the batteries BMS is obviously just rejecting the charge as full, and throwing something at the buggy system, which the means the buggy throws up an error message (5### - forgot to make a note of it). All power is lost, but easy to reset by simply turning ignition off/on again at bottom of hill. So questions are: Has anyone experienced this? If so - what have you done to fix it (we are simply charging to 95% instead of 100%) Anyone know how to disable the regen? We don't need it anyway. Cheers.

Well i took the dive and got x4 Allion GC2's. Very easy installation - virtually a battery swap as they are the same size. Only thing i had to do was make a couple of new cables, but that was easy enough. As someone else earlier in the thread said - night and day from the Discover batteries. So much weight removed the E1 site higher and the steering is now very easy. Max power is now available and it shoots up steep hills - something the Discover batteries never really did. Combo of weight removal and more power i think. All thats left is to update the Delta charger to a lithium profile, but so far, worth the $5k (Aus Dollars). If you are thinking of doing it, don't hesitate!

Depends if the BMS is 200, and is capable of being used in parallel, and allows doubling of amps. 99% of the reviews seem AI or server farm generated - too many red flags for me!

Only have steep hills here unfortunately! Might have to go for x5 Allion GC2 48v/30ah which can push out 65a for 20 secs, giving me 325a in total. Just Aus$6.5k. Expensive exercise! But hopefully that would be it for 5-10 Years. Might start with 4 and see how we go, and save up for a 5th!

hmmm - https://www.rjbatt.com.au/news-and-advice/relion-insight-series-48v-battery-recall Spike to RJ - they are stopping doing them - cant find another Aus supplier - do you know who else stocks them in Aus?

Anyone use the Allion AL4830-GC2? https://www.solarbatteriesonline.com.au/product/allion-lithium-ion-48v-battery-al4830-gc2/ Maximum continuous discharge current 60A (2C) Maximum peak discharge current 65A for 30 seconds, 100A for 10 second Would x4 be enough? Technically yes - 240a continuous/260a 30secs/400a 10secs - but thats at the limit of the battery ($5424) 5 might be better giving: 300a continuous/325a 30 secs/500a 10secs....but expensive AUS$6780!

The BMS installed our range of lithium batteries combine to provide greater load capacity - not greater throughput. We specifically choose to install BMS that don't increase in throughput amperage to protect the battery systems we manufacture from being used in applications they are not designed for (such as off grid storage, cranking, complex UPS etc...) Connecting a pair of 100A 48v lithium batteries will provide a 200A bank capacity - while the BMS will remain 200A continuous and 400A peak. There are lithium batteries on the market that have larger BMS - we don't sell nor deal in them, truth be told - but they are available May be worth looking into ranges such as the Lynx 400A 48v or Daly's own 400A 48v BMS unit. What application were you intending to use the batteries for that 200A continuous is not sufficient?

So its not usual for a 200a BMS to limit combined continuous output across multiple batteries in parallel? Most BMS systems will allow it the combined output? I still don't get how people are combining four 48v 50ah with 50a output batteries in parallel with a 100a BMS (for example) and getting enough current...

So my lack of knowledge is showing here: I was assuming i would need at least a 300a output for the E1 (the motor will go up to 400a i've read), so wanted to put two 200a continuous output batteries in (as above: https://www.aussiebatteries.com.au/giant-100ah-48v-lithium-golf-cart-deep-cycle-battery) and assumed i'd get 400a continuous in parallel. However, the reply from Giant customer service said the 200a BMS in each battery will not allow more than 200a output, even if paralled. So how do you double the amps in parallel if a BMS won't allow it? ...or am i being stupid and two of these batteries, even with only a 200a combined output still be enough for the E1 to climb steep hills? Cheers in advance.

So these Giant 48v/110ah batteries have just become available: https://www.aussiebatteries.com.au/giant-100ah-48v-lithium-golf-cart-deep-cycle-battery They look like they could drop in either side of the Controller that sits in the middle of the tray as they are 330mm(W) 355(L) 295mm(H). They can be paralleled, and I think two should be enough. Technically once paralleled the system should output 400ah continuous and 800ah Max (5 secs), more than enough for the E1 - probably 1/3rd more than is needed. However, the sales person stated that if the regen braking exceeded 400amps, it would put the batteries in standby mode for protection and they would have to be 're-started' with a jumper pack to reset them. Does anybody know the max output of the E1 Regen system, and if it does exceed that, is it possible to disable/bypass the regen so it has a zero output? Thanks.
