Based on that, I only need to charge about once a week which means this pack will easily outlive the cart even if I only get half the cycle life advertised.
I am using a DPI Gen IV charger in SLA mode and I modified it to include a supervisory circuit to disconnect the charger when the pack reaches 90% SOC. This eliminates the single-point failure risk of relying on the BMS alone to monitor charge progress.
Overall I am very happy with the change to LiFePO4 and these particular cells, but I cannot recommend the supplier I mentioned above since it appears that quite a few problems have occurred with deliveries over the past several months since I received mine. I guess I was lucky in that regard.

Very nice! I have a similar results with my 150ah battery from extreme team. I didn't feel comfortable enough building a battery pack like you did. I'm getting about 18 holes per 10% of battery. Similar to you 5-6 rounds then I charge usually down to 30% before I charge.
